Product details
Overview
BZD27B5V6P-HE3_A08 from Vishay Semiconductors is a surface-mount, AEC-Q101 qualified Zener diode with nominal breakdown voltage of 5.6 V, ±2 % tolerance, 100 mA test current, and 150 W peak surge power rating (10/1000 μs waveform). It operates as a precision voltage reference and transient voltage suppressor in automotive power rail protection circuits.
For engineers reviewing the BZD27B5V6P-HE3_A08 datasheet, BZD27B5V6P-HE3_A08 pinout, BZD27B5V6P-HE3_A08 application, or BZD27B5V6P-HE3_A08 equivalent, key selection criteria include its 5.49–5.71 V Zener range at 100 mA, 2 Ω dynamic resistance, -0.04 to +0.04 %/°C temperature coefficient, and DO-219AB (SMF) package compatibility with reflow soldering.
Technical Context
This unidirectional Zener diode uses silicon planar technology for stable voltage regulation and transient suppression. Its design supports both voltage reference operation (IZT = 100 mA) and clamping protection (VC = 10.9 V at IRSM = 13.3 A), with low leakage (≤10 μA at VR = 4.5 V) and high surge robustness (150 W PRSM).
Thermal performance is defined by RthJA = 180 K/W on 3 mm × 3 mm Cu pads and RthJL = 30 K/W, enabling operation up to TJ = 175 °C. It meets MSL level 1 per J-STD-020 and JESD 201 Class 2 whisker testing, with ESD ratings >8 kV HBM and >800 V MM.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0A-E3/52 | TVS diode (unidirectional), 5.0 V standoff, 100 W peak power, higher clamping voltage (9.2 V) | Designed for fast transient suppression, not precision regulation | Select for surge-only protection where regulation stability is secondary |
