This series offers a wide range of specifications and package configurations to give the designer wide flexibility. Typical applications of these Schottky diodes are mixing, detecting, switching, sampling, clamping, and wave shaping. The HSMS-2800 series of diodes is optimized for high voltage applications. The HSMS-2810 series of diodes features very low flicker (1/f) noise. The HSMS-2820 series of diodes is the best all-around choice for most applications, featuring low series resistance, low forward voltage at all current levels and good RF characteristics. The HSMS-2860 series is a high performance diode offering superior Vf and ultra-low capacitance. Note that HP’s manufacturing techniques assure that dice found in pairs and quads are taken from adjacent sites on the wafer, assuring the highest degree of match. 1 #3 2 BRIDGE QUAD 3 4 1 #8 2 1 #4 2 CROSS-OVER QUAD 3 4 1 #9 2 2 Electrical Specifications TA = 25°C, Single Diode[4] Part Package NumMarkber ing Lead HSMS[5] Code[3] Code Configuration 2800 A0 0 Single 2802 2803 2804 A2 A3 A4 2 3 4 2805 A5 5 2807 2808 A7 A8 7 8 Series Common Anode Common Cathode Unconnected Pair Ring Quad[6] Bridge Quad[6] 2810 B0 0 Single 2812 2813 2814 B2 B3 B4 2 3 4 2815 B5 5 2817 2818 B7 B8 7 8 Series Common Anode Common Cathode Unconnected Pair Ring Quad[6] Bridge Quad[6] 2820 C0 0 Single 2822 2823 2824 C2 C3 C4 2 3 4 2825 C5 5 2827 2828 2829 C7 C8 C9 7 8 9 Series Common Anode Common Cathode Unconnected Pair Ring Quad[6] Bridge Quad[6] Cross-over Quad 2860 2862 2863 2864 T0 T1 T3 T4 0 2 3 4 2865 T5 5 Test Conditions Single Series Pair Common Anode Common Cathode Unconnected Pair Nearest Equivalent Axial Lead Part No. 5082- Minimum Breakdown Voltage VBR (V) Maximum Forward Voltage VF (mV) Maximum Forward Voltage VF (V) @ IF (mA) Maximum Reverse Leakage IR (nA) @ VR (V) Maximum Capacitance CT (pF) Typical Dynamic Resistance RD (Ω) [6] 2800 (1N5711) 70 400 1.0 15 200 50 2.0 35 2810 (1N5712) 20 400 1.0 35 200 15 1.2 15 2835 15* 340 0.7 30 100 1.0 12 None 4 350 0.6 30 0.35 10 IR = 10 µA *IR = 100 µA IF = 1 mA[1] VF = 0 V f= 1.0 MHz[2] IF = 5 mA — 1 Notes: 1. ∆VF for diodes in pairs and quads in 15 mV maximum at 1 mA. 2. ∆CTO for diodes in pairs and quads is 0.2 pF maximum. 3.

Quad Capacitance Capacitance of Schottky diode quads is measured using an HP4271 LCR meter. This instrument effectively isolates individual diode branches from the others, allowing accurate capacitance measurement of each branch or each diode. The conditions are: 20 mV R.M.S. voltage at 1 MHz. HP defines this measurement as “CM”, and it is equivalent to the capacitance of the diode by itself. The equivalent diagonal and adjacent capacitances can then be calculated by the formulas given below. In a quad, the diagonal capacitance is the capacitance between points A and B as shown in the figure below. The diagonal capacitance is calculated using the following formula The equivalent adjacent capacitance is the capacitance between points A and C in the figure below. This capacitance is calculated using the following formula C1 x C2 C3 x C4 CDIAGONAL = _______ + _______ C3 + C4 C1 + C2 1 CADJACENT = C1 + ____________ 1 1 1 –– + –– + –– C2 C 3 C4 A C1 C3 C2 C4 This information does not apply to cross-over quad diodes.
