Product details
Overview
BZD27B180P-HE3_A08 from Vishay Semiconductors is a 180 V, ±2 % tolerance AEC-Q101 qualified Zener diode in SOD-123W-compatible SMF (DO-219AB) package, rated for 150 W non-repetitive peak surge power and 2300 mW total power dissipation at TL = 105 °C, used for overvoltage protection in automotive power rails.
For engineers reviewing the BZD27B180P-HE3_A08 datasheet, BZD27B180P-HE3_A08 pinout, BZD27B180P-HE3_A08 application, or BZD27B180P-HE3_A08 equivalent, key selection criteria include its 180 V nominal Zener voltage, 5 mA test current, 150 V clamping voltage at 5 A, -65 to +175 °C operating range, and AEC-Q101 qualification for under-hood automotive use.
Technical Context
This unidirectional Zener diode operates as a precision voltage clamp with low dynamic resistance (180 Ω typical at IZT = 5 mA) and a positive temperature coefficient of +0.09 to +0.13 %/°C. It delivers stable regulation under transient conditions via its 150 W 10/1000 μs surge rating and 300 W 100 μs pulse capability.
Designed for surface-mount reflow soldering, it meets MSL level 1 per J-STD-020 (peak 260 °C), JESD 201 Class 2 whisker test, and AEC-Q101 stress requirements including >8 kV HBM ESD. Its SMF (DO-219AB) package enables high-power density in compact layouts.
Key Specifications
