Product details
Overview
BZD27B3V6P-HE3_A18 from Vishay Semiconductors is a silicon planar Zener diode optimized for precision voltage regulation and transient overvoltage protection in automotive-grade power rails, with nominal Zener voltage 3.6 V (±2 %), 100 mA test current, 150 W peak surge power rating, and AEC-Q101 qualification for under-hood electronics.
For engineers reviewing the BZD27B3V6P-HE3_A18 datasheet, BZD27B3V6P-HE3_A18 pinout, BZD27B3V6P-HE3_A18 application, or BZD27B3V6P-HE3_A18 equivalent, this page delivers verified package dimensions, thermal resistance values, clamping voltage at surge current, temperature coefficient, and AEC-Q101 compliance status - all confirmed from Vishay's official Rev. 2.1 datasheet (Doc. #85921).
Technical Context
This unidirectional Zener diode operates as a shunt voltage reference and transient voltage suppressor in low-voltage DC systems. Its ±2 % VZ tolerance at 100 mA and -0.14 to -0.04 %/°C temperature coefficient enable stable regulation across automotive temperature ranges (-65 °C to +175 °C).
The device uses the SMF (DO-219AB) package with MSL Level 1 moisture sensitivity and JESD 201 Class 2 whisker resistance. It supports wave and reflow soldering up to 260 °C peak, and delivers 13.3 V clamping voltage at 13.3 A IRSM, per IEC 60-1 10/1000 μs waveform.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C3V6LT1G | ±5 % VZ tolerance, SOT-23 package, 300 mW Ptot, no AEC-Q101 qualification | Limited to commercial-grade consumer electronics; unsuitable for automotive environments | Select only for cost-sensitive, non-automotive applications where ±5 % regulation is acceptable |
| SMBJ3.3A | TVS diode (not Zener), 3.3 V standoff, 600 W PPPM, bidirectional, higher capacitance | Designed for ESD/surge suppression, not precision regulation; lacks stable DC reference behavior | Choose when primary need is high-energy transient clamping-not stable voltage reference |
Compared with BZD27B3V6P-HE3_A18, BZX84-C3V6LT1G trades AEC-Q101 reliability and ±2 % accuracy for lower cost and smaller footprint, while SMBJ3.3A provides superior surge handling but cannot serve as a DC voltage reference due to its TVS architecture and wider VBR distribution.

FAQ
What is the Zener voltage tolerance for BZD27B3V6P-HE3_A18?
The BZD27B3V6P-HE3_A18 has a Zener voltage tolerance of ±2 %, specified as 3.53 V minimum to 3.67 V maximum at 100 mA test current (IZT). This tight tolerance is confirmed in Vishay's official datasheet (Doc. #85921, Rev. 2.1) and enables use in precision reference applications without external calibration. The BZD27B3V6P-HE3_A18 achieves this via silicon planar process control and post-package screening.
Is BZD27B3V6P-HE3_A18 qualified for automotive applications?
Yes, BZD27B3V6P-HE3_A18 is AEC-Q101 qualified, as indicated by the "-HE3" suffix per Vishay's ordering nomenclature. It meets JESD201 Class 2 whisker testing, MSL Level 1 per J-STD-020, and operates across -65 °C to +175 °C. The BZD27B3V6P-HE3_A18 is explicitly intended for under-hood and chassis-mounted automotive electronics per Vishay's product definition.
What is the clamping voltage of BZD27B3V6P-HE3_A18 under surge conditions?
The clamping voltage (VC) of BZD27B3V6P-HE3_A18 is 13.3 V at 13.3 A peak surge current (IRSM) for a 10/1000 μs waveform, per IEC 60-1. This value is measured at TJ = 25 °C and defines the maximum voltage imposed on protected circuitry during standardized automotive transients. The BZD27B3V6P-HE3_A18 maintains this performance due to its 150 W PRSM rating.
Which package does BZD27B3V6P-HE3_A18 use, and what are its key mechanical features?
BZD27B3V6P-HE3_A18 uses the SMF (DO-219AB) package: a low-profile surface-mount case measuring 2.7–2.9 mm × 1.7–1.9 mm × 0.8–1.2 mm, with cathode marked by a bar on the top surface. It is compatible with SOD-123W footprints and rated for reflow up to 260 °C peak. The BZD27B3V6P-HE3_A18 package meets UL 94 V-0 flammability and JESD201 Class 2 whisker standards.
How does the temperature coefficient affect BZD27B3V6P-HE3_A18 performance in real-world circuits?
The BZD27B3V6P-HE3_A18 exhibits a temperature coefficient (αVZ) ranging from -0.14 %/°C to -0.04 %/°C, meaning its Zener voltage decreases slightly as junction temperature rises. At 100 °C ΔT, VZ shifts by approximately -0.036 V to -0.014 V - critical for high-accuracy references. The BZD27B3V6P-HE3_A18's tight αVZ spread ensures predictable drift in automotive and industrial thermal environments.
