Product details
Overview
BZD27B3V6P-HE3_A08 from Vishay Semiconductors is a surface-mount silicon planar Zener diode rated for 3.6 V nominal Zener voltage (±2 % tolerance), 100 mA test current, and 150 W non-repetitive peak surge power (10/1000 μs waveform), designed for precision voltage regulation and transient overvoltage protection in automotive power rails and industrial sensor interfaces.
For engineers reviewing the BZD27B3V6P-HE3_A08 datasheet, BZD27B3V6P-HE3_A08 pinout, BZD27B3V6P-HE3_A08 application, or BZD27B3V6P-HE3_A08 equivalent, this AEC-Q101 qualified device offers verified surge robustness, low dynamic impedance (4 Ω typ.), tight voltage tolerance, and MSL Level 1 reflow compatibility - critical for high-reliability board-level ESD and load-dump suppression design.
Technical Context
The BZD27B3V6P-HE3_A08 operates as a unidirectional, single-element Zener diode with a nominal breakdown voltage of 3.6 V at 100 mA, exhibiting a temperature coefficient of –0.14 to –0.04 %/°C and dynamic resistance of 4 Ω (typ.) at IZT. Its clamping behavior under surge conditions is defined by a 10.9 V maximum clamping voltage at 13.3 A peak reverse current (10/1000 μs).
It features low leakage (≤1 μA at 2.88 V), forward voltage ≤1.2 V at 0.2 A, and thermal resistance of 180 K/W (junction-to-ambient on 3 mm × 3 mm Cu pad), enabling stable operation up to TJ = 175 °C in compact SOD-123W-compatible SMF (DO-219AB) packaging.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation and surge protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ3.3A | TVS diode (not Zener-regulated); 3.3 V standoff, 13.3 V clamping, 600 W peak power | Better for high-energy transients but lacks precision regulation; higher leakage (~10 μA) | Select when primary need is surge absorption rather than voltage reference stability |
| BZX84-C3V6 | SOT-23 Zener; same 3.6 V nominal, ±5 % tolerance, 300 mW PD, no surge rating | Lower cost, smaller footprint, but not AEC-Q101 qualified or surge-rated | Select for non-automotive, low-power logic rail clamping where 150 W surge immunity is unnecessary |
Compared with SMBJ3.3A and BZX84-C3V6, the BZD27B3V6P-HE3_A08 uniquely combines AEC-Q101 qualification, ±2 % Zener tolerance, and 150 W surge capability in a thermally robust SMF package - making it optimal for automotive and industrial designs requiring both precision regulation and transient resilience.
