| (R) TAK CHEONG SEM IC O N DU C TO R 500 mW DO-35 Hermetically Sealed Glass Zener Voltage Regulators Absolute Maximum Ratings Parameter Power Dissipation Storage Temperature Range Operating Junction Temperature TA = 25C unless otherwise noted Value 500 -65 to +200 +200 Units mW C C AXIAL LEAD DO35 DEVICE MARKING DIAGRAM L 43 xx T L : Logo Device Code : TC1N43xxT Tolerance (T) : (Blank) :A C :D These ratings are limiting values above which the serviceability of the diode may be impaired. Specification Features: Zener Voltage Range 2.4 to 3 Volts DO-35 Package (JEDEC) Through-Hole Device Type Mounting Hermetically Sealed Glass Compression Bonded Construction All External Surfaces Are Corrosion Resistant And Leads Are Readily Solderable RoHS Compliant Solder Hot Dip Tin (Sn) Lead Finish Cathode Indicated By Polarity Band Cathode = 10% = 5% = 2% = 1% Anode ELECTRICAL SYMBOL Electrical Characteristics Device Type TC1N4370A TC1N4371A TC1N4372A VZ @ IZT (Volts) Nominal 2.4 2.7 3 TA = 25C unless otherwise noted IZT (mA) 20 20 20 ZZT @ IZT () Max 30 30 29 IR @ VR (A) Max 100 75 50 VR (Volt) 1 1 1 VF Forward Voltage = 1.5 V Maximum @ IF = 200 mA for all types Notes: 1. TOLERANCE AND VOLTAGE DESIGNATION The type numbers listed have zener voltage as shown and have a standard tolerance on the nominal zener voltage of 5%. Suffix (BLANK) = 10%, Suffix C = 2% and D = 1%. 2. SPECIALS AVAILABLE INCLUDE Nominal zener voltages between the voltages shown and tighter voltage, for detailed information on price, availability and delivery, contact you nearest Tak Cheong representative. 3. ZENER VOLTAGE (VZ) MEASUREMENT The zener voltage (VZ) is tested under pulse condition. The measured VZ is guaranteed to be within specification with device junction in thermal equilibrium. 4. ZENER IMPEDANCE (ZZ) DERIVATION Zener impedance is derived from the 60-cycle ac voltage, which results when an ac current having an RMS value equal to 10% of the dc zener current (IZT) is superimposed to IZT .
