Product details
Overview
BZD27B16P-HE3_A08 from Vishay Semiconductors is an AEC-Q101 qualified, unidirectional silicon planar Zener diode in DO-219AB (SMF) package, with nominal Zener voltage 16 V ±2 % at 25 mA test current, dynamic resistance 12 Ω, and temperature coefficient +0.06 to +0.11 %/°C - used for precision voltage regulation and overvoltage protection in automotive power rails.
For engineers reviewing the BZD27B16P-HE3_A08 datasheet, BZD27B16P-HE3_A08 pinout, BZD27B16P-HE3_A08 application, or BZD27B16P-HE3_A08 equivalent, key selection criteria include its 150 W 10/1000 μs surge rating, 21.9 V clamping voltage at 6.6 A peak pulse current, MSL Level 1 reflow compatibility, and AEC-Q101 qualification for under-hood automotive use.
Technical Context
This device operates as a single-element, unidirectional Zener diode optimized for stable voltage reference and transient voltage suppression. Its low dynamic resistance (12 Ω) and tight ±2 % VZ tolerance support accurate regulation in feedback loops, while its 175 °C max junction temperature and 150 W non-repetitive surge rating enable robust operation in high-temperature automotive environments.
The BZD27B16P-HE3_A08 features a silicon planar construction with ESD ratings >8 kV HBM and >800 V MM, meets JESD201 Class 2 whisker test, and is wave/reflow solderable per J-STD-020 MSL Level 1 (260 °C peak). It is not a bidirectional TVS but a precision-regulating Zener with defined forward conduction (VF ≤1.2 V @ 0.2 A).
Key Specifications

FAQ
What is the Zener voltage tolerance of BZD27B16P-HE3_A08?
The BZD27B16P-HE3_A08 has a Zener voltage tolerance of ±2 %, specified as 15.68 V minimum to 16.32 V maximum at 25 mA test current (IZT). This tight tolerance enables high-accuracy voltage regulation in feedback paths of DC-DC converters and reference circuits where minimal drift is required. The BZD27B16P-HE3_A08 achieves this via silicon planar process control and post-package screening.
Is BZD27B16P-HE3_A08 qualified for automotive applications?
Yes, the BZD27B16P-HE3_A08 is AEC-Q101 qualified and rated for operation from -65 °C to +175 °C junction temperature. It meets JESD201 Class 2 whisker testing and supports reflow soldering up to 260 °C (MSL Level 1). These qualifications make the BZD27B16P-HE3_A08 suitable for under-hood automotive modules including ECUs, BCMs, and ADAS power supplies.
What is the clamping voltage of BZD27B16P-HE3_A08 under surge conditions?
The BZD27B16P-HE3_A08 has a clamping voltage (VC) of 21.9 V at a peak pulse current (IRSM) of 6.6 A using the 10/1000 μs waveform. This value is measured per IEC 60-1 and defines the maximum voltage imposed on downstream circuitry during transient events. The BZD27B16P-HE3_A08 maintains this clamping performance across its full operating temperature range.
Can BZD27B16P-HE3_A08 be used in place of a standard TVS diode?
The BZD27B16P-HE3_A08 functions as both a precision Zener regulator and a transient suppressor, but differs from general-purpose TVS diodes in key ways: it offers ±2 % VZ tolerance and low dynamic resistance (12 Ω) for regulation, whereas TVS devices prioritize high surge power (e.g., 400 W) with looser voltage specs. The BZD27B16P-HE3_A08 is optimal where regulation accuracy and surge protection are both required - such as in regulated power monitor circuits.
What package type does BZD27B16P-HE3_A08 use, and what are its mounting requirements?
The BZD27B16P-HE3_A08 uses the DO-219AB (SMF) package: 2.7 mm × 3.5 mm × 0.85 mm, with cathode marking and MSL Level 1 rating. It supports standard Pb-free reflow profiles up to 260 °C peak temperature. Recommended PCB pad layout uses 3 mm × 3 mm copper pads ≥40 μm thick for optimal thermal dissipation. The BZD27B16P-HE3_A08 must be mounted with correct cathode orientation per tape carrier diagram.
