Product details
Overview
BZD27B100P-HE3_A18 from Vishay Semiconductors is a surface-mount, AEC-Q101 qualified Zener diode with nominal breakdown voltage of 100 V, ±2 % tolerance, 5 mA test current, and 134 V clamping voltage at 1.1 A surge current. It delivers 150 W non-repetitive peak surge power (10/1000 μs), operates from −65 °C to +175 °C, and is used for overvoltage protection in automotive power supply rails.
For engineers reviewing the BZD27B100P-HE3_A18 datasheet, BZD27B100P-HE3_A18 pinout, BZD27B100P-HE3_A18 application, or BZD27B100P-HE3_A18 equivalent, key selection criteria include its 100 V Zener voltage tolerance, 150 W surge rating, DO-219AB (SMF) package compatibility, AEC-Q101 qualification, and low leakage (<5 μA at 82 V).
Technical Context
This unidirectional Zener diode functions as a precision voltage clamp and transient suppressor in DC power systems. Its design integrates low dynamic impedance (75 Ω max at 5 mA), tight ±2 % VZ tolerance, and a positive temperature coefficient (+0.09 to +0.13 %/°C) optimized for stable regulation under thermal stress.
The device uses silicon planar construction and is housed in an eSMP® SMF (DO-219AB) package with MSL level 1 moisture sensitivity, JESD 201 Class 2 whisker resistance, and wave/reflow solder compatibility. It meets AEC-Q101 for automotive reliability, including >8 kV HBM ESD rating.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A-E3/52 | TVS diode (not Zener); 100 V standoff, 17.3 A peak pulse current, 1500 W peak power | Designed for fast-rising ESD/lightning; slower response than Zener but higher energy absorption | Select when surge energy exceeds 150 W or rise time <1 ns; not suitable for precision voltage regulation |
| BZX84-C100LT1G | SOT-23 Zener; 100 V nominal, ±5 % tolerance, 200 mW power, 100 Ω ZZ | Limited to low-energy protection; not AEC-Q101 qualified or surge-rated | Use only in non-automotive, low-power signal-level clamping where cost and size outweigh reliability needs |
Compared with BZD27B100P-HE3_A18, SMBJ100A-E3/52 offers higher surge capacity but lacks precision regulation and temperature stability, while BZX84-C100LT1G provides compact packaging but fails to meet automotive surge or thermal requirements.

FAQ
What is the Zener voltage tolerance of BZD27B100P-HE3_A18?
The BZD27B100P-HE3_A18 has a Zener voltage tolerance of ±2 %, specified as 98.0 V to 102.0 V at 5 mA test current. This tight tolerance ensures predictable clamping behavior in 100 V nominal systems and reduces design margin overhead compared to wider-tolerance alternatives. The value is measured per Vishay Document 85921 Rev. 2.1 and applies across the full operating temperature range.
Is BZD27B100P-HE3_A18 qualified for automotive use?
Yes, BZD27B100P-HE3_A18 is AEC-Q101 qualified, with documented testing for temperature cycling, humidity bias, mechanical shock, and ESD (HBM >8 kV, MM >800 V). Its DO-219AB package meets JESD 201 Class 2 whisker requirements and MSL Level 1, making it suitable for under-hood and chassis-mounted automotive modules. This qualification is explicitly stated in the ordering code suffix "-HE3".
What is the maximum clamping voltage of BZD27B100P-HE3_A18 during surge events?
The BZD27B100P-HE3_A18 clamps to a maximum of 134 V at 1.1 A peak reverse current (10/1000 μs waveform), per Vishay's Electrical Characteristics table on page 3 of document 85921. This value defines the upper voltage limit imposed on protected circuits during standardized load-dump transients and is guaranteed across −65 °C to +175 °C junction temperature.
Can BZD27B100P-HE3_A18 be used in reflow soldering processes?
Yes, BZD27B100P-HE3_A18 is fully compatible with lead-free reflow soldering, with a maximum peak temperature rating of 260 °C per J-STD-020 MSL Level 1. Its DO-219AB (SMF) package is qualified for both wave and reflow processes, and no pre-bake is required. The device's thermal resistance (RthJA = 180 K/W on 3 mm × 3 mm Cu pads) supports reliable thermal performance post-assembly.
What is the leakage current specification for BZD27B100P-HE3_A18 at rated voltage?
BZD27B100P-HE3_A18 exhibits a maximum reverse leakage current of 5 μA at 82 V (VWM), per the Electrical Characteristics table on page 3 of Vishay document 85921. This low leakage preserves efficiency in high-impedance bias networks and ensures minimal power loss in always-on automotive modules, even at maximum operating temperature (175 °C).
