Storage temperature range Tstg −30~100 °C Soldering temperature (5 s), (Note 2) Tsol 260 °C * Includes resin-mold portion ( ) : Reference Value 4-3EA1 Pin Connection 1 2 1. Anode 2. Cathode Note: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook (“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test report and estimated failure rate, etc). Note 1: f = 100 kHz, duty = 1% Note 2: Soldering must be performed 2 mm from the bottom of the package body. 1 2007-10-01 TLN238(F) Optical and Electrical Characteristics (Ta = 25°C) Characteristics Symbol Test Condition Min Typ.

Handling Precautions • Soldering must be performed under the stopper. • When forming the leads, bend each lead at least 5 mm from the package body. Soldering must be performed after the leads have been formed. • The radiant intensity decreases over time due to current flowing in the infrared LED. When designing circuits, take into account the change in radiant intensity over time. 2 2007-10-01 TLN238(F) IF – Ta IF – V F 75°C (mA) 100 80 60 40 −25°C 10 1 85°C 0°C Ta = 25°C 50°C 0.1 20 0 0 20 40 60 80 0.01 0.8 100 1 1.2 Ambient temperature Ta (°C) VF – Ta 1.6 1.8 2 (V) IFP – VFP (typ.)
