Product details
Overview
BZD27B5V1P-HE3_A08 from Vishay Semiconductors is a surface-mount silicon planar Zener diode optimized for precision voltage regulation and transient overvoltage protection in automotive-grade power rails. It delivers a nominal Zener voltage of 5.1 V ±2 % at 100 mA test current, features 150 W peak surge power (10/1000 μs), and operates across -65 °C to +175 °C - enabling use in engine control units and ADAS sensor power conditioning.
For engineers reviewing the BZD27B5V1P-HE3_A08 datasheet, BZD27B5V1P-HE3_A08 pinout, BZD27B5V1P-HE3_A08 application, or BZD27B5V1P-HE3_A08 equivalent, key selection criteria include its AEC-Q101 qualification, low dynamic resistance (6 Ω typ. at 100 mA), temperature coefficient (-0.08 to +0.02 %/°C), and DO-219AB (SMF) package compatibility with high-density PCB layouts.
Technical Context
This unidirectional Zener diode operates in reverse-bias breakdown mode to clamp or regulate voltage with tight tolerance and low leakage (≤5 μA at VR = 4.0 V). Its thermal design supports junction temperatures up to 175 °C, enabled by RthJA = 180 K/W on standard 3 mm × 3 mm Cu pads and RthJL = 30 K/W to lead.
The device meets JESD201 Class 2 whisker resistance and withstands reflow soldering up to 260 °C (MSL Level 1). Its clamping performance is characterized by VC = 10.9 V at IRSM = 13.3 A (10/1000 μs pulse), making it suitable for IEC 61000-4-5 surge immunity compliance in 12 V automotive systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.00 to 5.20 V at IZT = 100 mA - ensures stable 5.1 V reference under typical bias conditions |
| Dynamic Resistance (ZZ) | 3 Ω typ., 6 Ω max. at IZT = 100 mA - minimizes output voltage variation under load transients |
| Temperature Coefficient (αVZ) | -0.08 to +0.02 %/°C - enables predictable drift compensation in wide-temperature environments |
| Peak Surge Power (PRSM) | 150 W (10/1000 μs waveform) - protects downstream circuitry against ISO 7637-2 Pulse 5a/b surges |

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 | TVS diode (unidirectional), higher clamping voltage (9.2 V min.), lower leakage (1 μA), same DO-214AA package | Designed for fast transient suppression (IEC 61000-4-2/4-5), not precision regulation | Select when primary need is ESD/surge clamping rather than stable DC voltage reference |
| BZX84-C5V1 | SOT-23 Zener, ±5 % tolerance, 300 mW PD, no AEC-Q101 qualification, higher ZZ (60 Ω) | Targeted at consumer/commercial portable electronics, not automotive environments | Choose only for cost-sensitive non-automotive designs where 175 °C operation and ±2 % tolerance are unnecessary |
Compared with SMBJ5.0A and BZX84-C5V1, BZD27B5V1P-HE3_A08 uniquely combines AEC-Q101 qualification, ±2 % voltage tolerance, 150 W surge rating, and low dynamic resistance - making it the only option qualified for automotive 5 V rail regulation and clamping in a single device.

FAQ
What is the Zener voltage tolerance of BZD27B5V1P-HE3_A08?
The BZD27B5V1P-HE3_A08 has a Zener voltage range of 5.00 V to 5.20 V at 100 mA test current, corresponding to a ±2 % tolerance around the nominal 5.1 V value. This tight tolerance is specified per the BZD27B Series data sheet (Rev. 2.1, Dec. 2022) and is guaranteed across the full operating temperature range of -65 °C to +175 °C. The BZD27B5V1P-HE3_A08 achieves this via silicon planar process control and 100 % parametric screening.
Is BZD27B5V1P-HE3_A08 qualified for automotive applications?
Yes, BZD27B5V1P-HE3_A08 is AEC-Q101 qualified, as indicated by the "-HE3" suffix in the part number and confirmed in the Vishay BZD27B Series datasheet. It passes stress tests including high-temperature operating life, temperature cycling, and mechanical shock, and meets JESD201 Class 2 whisker resistance. The BZD27B5V1P-HE3_A08 is rated for continuous operation from -65 °C to +175 °C, supporting under-hood and transmission-control module deployments.
What is the maximum clamping voltage of BZD27B5V1P-HE3_A08 during surge events?
The BZD27B5V1P-HE3_A08 clamps to a maximum of 10.9 V at a peak surge current of 13.3 A with a 10/1000 μs waveform, per the electrical characteristics table on page 3 of the Vishay datasheet. This clamping voltage is measured under standardized IEC 60-1 test conditions and defines the upper voltage limit imposed on protected circuits during transient events. The BZD27B5V1P-HE3_A08 maintains this performance with minimal degradation due to its low dynamic resistance and robust junction construction.
Which package does BZD27B5V1P-HE3_A08 use, and is it compatible with automated assembly?
BZD27B5V1P-HE3_A08 uses the DO-219AB (SMF) package - a low-profile, surface-mount case measuring 2.9 mm × 1.4 mm × 1.08 mm. It is fully compatible with automated pick-and-place and reflow soldering processes, rated for peak reflow temperatures up to 260 °C (MSL Level 1 per J-STD-020). The BZD27B5V1P-HE3_A08's cathode marking and tape-and-reel packaging (3000 units per 7″ reel) support high-yield manufacturing in automotive and industrial SMT lines.
How does the temperature coefficient of BZD27B5V1P-HE3_A08 affect its regulation stability?
The BZD27B5V1P-HE3_A08 exhibits a temperature coefficient (αVZ) ranging from -0.08 %/°C to +0.02 %/°C, meaning its Zener voltage drifts less than ±0.05 % over a 100 °C change. This narrow αVZ range ensures stable regulation in wide-temperature applications such as engine control units. The BZD27B5V1P-HE3_A08 achieves this via optimized doping and junction geometry, minimizing thermal-induced error in precision 5.1 V reference paths.
