Replacing power transistors by low VCEsat (BISS) transistors
1. Introduction
This application note provides information on how to make use of a cost saving
opportunity by replacing older medium power and power transistors by Philips’ low VCEsat
(BISS) transistors1. A cross reference table provides a cross reference for leaded and
SMD types. Further spreadsheets show a comparison of the most common parameters
(VCEO, IC, VCEsat and hFE).
2. Reduced power dissipation due to low saturation voltage
The low saturation voltage VCEsat, high collector current capability IC(max) and high current
gain hFE make BISS transistors an excellent alternative to older medium power
transistors in SOT54 (TO-92), SOT223 (SC-73) and SOT89 (SC-62) and power
transistors in DPAK, TO-220 and TO-126. Particularly, for switching applications the
transistors’ power dissipation is significantly lower due to a low collector-emitter
saturation voltage as the following example shows:
Table 1:
BISS transistors dissipate less power enabling to select smaller and cheaper
packages

Due to the lower power dissipation transistors with a smaller package can be selected.
The PBSS5350S in SOT54 (TO-92) for example replaces a BD132 in TO-126. Keeping
in mind that for discrete semiconductors package costs are higher than the cost for the
silicon savings can be realized by using small SOT54 BISS transistors. Additionally, the
circuit efficiency increases and less board space is necessary.
Further, BISS transistors present a higher current gain hFE. As a result, less base current
is required to control the transistor which takes load from the driving circuit.
While for switching applications VCEsat is very low, the higher VCE for linear applications
leads to a higher power dissipation. A replacement with BISS transistors is limited to
830 mW for leaded BISS transistors and to 1350 mW for surface mount applications
(2 W for SOT223 transistors on 6 cm² collector mounting pad).

Replacing power transistors by low VCEsat (BISS) transistors
Only a few BISS transistor types are necessary to replace numerous power transistors:
• PBSS8110_ / PBSS9110_
1 A / 100 V and
• PBSS4350_ / PBSS5350_
3 A / 50 V replace
- power transistors with 1 – 3 A rated collector current.
• PBSS4540Z / PBSS5540Z
5 A / 40 V and
• PBSS302ND / PBSS302PD
4 A / 40 V replace
- power transistors with 4 – 5 A rated collector current.
Table 19: - Table 24: show the most common parameters of these types for reference.
3. Common replacements
Many popular transistors are included in the cross reference table (Table 2:). Main cross
reference data given in Table 3: – Table 18: are provided to confirm the selection. For
SMD replacements these tables provide up to three alternatives with the same electrical
but different thermal specifications. This enables to use the smallest package possible
depending on the actual power dissipation.
The BISS transistors in Table 2: are selected with focus on reducing the number of types.
This implies that the provided replacement must not necessarily be the optimum solution
with regard to the achievable power dissipation.

4. General selection process
For transistors not included in the cross reference table the following steps need to be
done by comparing the data sheets:
1. Limiting values, VCEO: BISS transistors must have equal or higher value.
2. Limiting values, IC: BISS transistors must have equal or higher value.
3. Characteristics, VCEsat(max): BISS transistors must have equal or lower value,
pay attention to comparable operating conditions IC and IB. Notes to VCEsat:
- This parameter is mostly important for switching applications
(i.e. not relevant for linear applications).
- The lower the ratio IC/IB the lower the saturation voltage but the higher the
required base current.
- VCEsat values of BISS transistors are far below the values of power transistors.
4. Characteristics, hFE(min): BISS transistors must have equal or higher value,
pay attention to comparable operating conditions IC and VCE. Notes to hFE:
- This parameter is important for linear and switching applications.
- The higher VCE the higher the current gain at a specified current.
- hFE values of BISS transistors are far above the values of power transistors.
5. Calculate resulting power dissipation Ptot to select the most appropriate package.
• Switching applications: Ptot = VCEsat x IC + VBEsat x IB
• Linear applications: Ptot = VCE x IC + VBE x IB
Notes to Ptot:
- For a rough estimation the input power dissipation (VBE(sat) x IB) can be
neglected.
- For linear applications power dissipation may become an issue since VCE is
significantly higher than VCEsat in switching applications.
- For the package selection the mounting conditions must be considered:
SOT54
SOT223*)
SOT89*)
SOT457*)
SOT23*)
*)
0.83 W
1 – 1.35 W
1W
0.6 W
0.48 W
Mounted on 1 cm² collector mounting pad
- For switching applications a high power dissipation capability of the package is
often not necessary anymore since the heat generation is much lower using
BISS transistors due to the very low VCEsat values.
- An even lower power dissipation due to lower VCEsat values can be achieved by
selecting BISS transistors with a lower VCEO value. For example if the
application requires only 20 V breakdown voltage, a 20 V transistor should be
used instead of a 40 V transistor.
For most of the medium power and power transistors the types given in Table 19:–
Table 24: should be sufficient. If not please look for data sheets of transistors starting
with “PBSS” on the Internet or contact your nearest Philips sales office.
