Product details
Overview
BZW04-15HE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on signal and power lines. It features a 15.3 V stand-off voltage (VWM), 17.1–18.9 V breakdown voltage (VBR) at 1 mA test current, 25.2 V maximum clamping voltage (VC) at 16.0 A peak pulse current (IPPM), and 400 W peak pulse power (PPPM) with 10/1000 μs waveform - used to protect MOSFETs, sensor interfaces, and microcontroller I/O in automotive and industrial control systems.
For engineers reviewing the BZW04-15HE3/54 datasheet, BZW04-15HE3/54 pinout, BZW04-15HE3/54 application, or BZW04-15HE3/54 equivalent, this device is evaluated for AEC-Q101 qualified surge protection in harsh environments where low clamping voltage, fast response (<1 ns), and stable temperature coefficient (0.088 %/°C) are critical for reliable overvoltage immunity.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with identical VBR min/max, VC, and IPPM ratings in forward and reverse directions. Its glass-passivated junction ensures low leakage (<1 μA at VWM) and robust surge handling up to 400 W under repetitive 10/1000 μs pulses at 0.01% duty cycle.
The device is rated for TJ = –55 °C to +175 °C operation, with thermal derating above 25 °C per Fig. 2, and meets JESD201 Class 2 whisker resistance due to its HE3 suffix - confirming suitability for automotive-grade soldering and long-term reliability in engine control units and body electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 15.3 V - maximum continuous reverse working voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (min/max) | 17.1 V / 18.9 V at 1 mA - precise breakdown threshold ensuring predictable turn-on during transients. |
| VC @ IPPM | 25.2 V at 16.0 A - clamping voltage limits downstream component stress during 400 W surge events. |
| PPPM | 400 W - peak pulse power rating with 10/1000 μs waveform, enabling protection against lightning-induced and inductive-switching surges. |
| ID @ VWM | <1 μA - ultra-low reverse leakage preserves signal integrity and minimizes standby power loss in high-impedance circuits. |
| TJ max. | +175 °C - extended junction temperature rating supports under-hood automotive deployment without derating penalties. |
| Temp. coeff. | 0.088 %/°C - stable VBR drift ensures consistent clamping performance across wide ambient ranges. |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with axial leads; no polarity marking for bidirectional configuration - terminals are electrically symmetrical and interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both ends function identically as clamping terminals; no cathode band - enables flexible PCB layout in AC-coupled or differential signal lines. |
| Lead 1 / Lead 2 | Connection interface | Matte tin-plated, J-STD-002 compliant leads support wave and reflow soldering; 275 °C/10 s solder dip tolerance ensures process robustness. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including powertrain and chassis modules requiring zero-failure reliability under thermal cycling and mechanical shock. |
| Glass passivated junction | Eliminates surface contamination sensitivity and improves long-term stability of VBR and leakage versus silicon-only alternatives. |
| 400 W 10/1000 μs rating | Supports IEC 61000-4-5 Level 3 (1 kV line-to-line, 2 kV line-to-earth) surge immunity without external series impedance. |
| Low clamping ratio (VC/VBR ≈ 1.44) | Minimizes let-through voltage to protect 3.3 V and 5 V logic rails while maintaining margin above IC absolute maximum ratings. |
| JESD201 Class 2 whisker resistance | Enables use in high-reliability automotive assemblies where tin whisker growth could cause latent field failures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15CA | DO-214AA package (SMB), 15 V VWM, 24.4 V VC @ 16.3 A, 600 W PPPM | Higher power rating but larger footprint; lower thermal resistance than DO-41 | Select when board space permits larger package and higher surge margin is required beyond 400 W. |
| P6KE15CA | DO-15 package, 15 V VWM, 24.4 V VC @ 16.3 A, 600 W PPPM, non-AEC-Q101 | Same clamping performance but lacks automotive qualification and whisker resistance | Acceptable for commercial/industrial use where AEC-Q101 and JESD201 Class 2 are not mandated. |
Compared with BZW04-15HE3/54, SMBJ15CA offers higher surge capacity in a surface-mount format ideal for automated assembly, while P6KE15CA provides cost-effective protection without automotive compliance - making BZW04-15HE3/54 the optimal choice where AEC-Q101, DO-41 through-hole compatibility, and proven under-hood reliability are mandatory.

FAQ
What is the polarity configuration of BZW04-15HE3/54?
BZW04-15HE3/54 is a bidirectional TVS diode with symmetrical electrical characteristics in both directions. It has no cathode marking and functions identically regardless of terminal orientation - making it suitable for AC signal lines, differential buses, and ungrounded power rails where polarity reversal may occur.
Is BZW04-15HE3/54 qualified for automotive applications?
Yes, BZW04-15HE3/54 carries the HE3 suffix, which denotes AEC-Q101 qualification and JESD201 Class 2 whisker resistance. This confirms its suitability for automotive applications including body control modules, lighting drivers, and infotainment power supplies where reliability under thermal cycling and vibration is essential.
What does the "/54" in BZW04-15HE3/54 indicate?
The "/54" suffix specifies the preferred packaging code: 13-inch diameter paper tape and reel, with a base quantity of 550 units per reel. This format supports automated pick-and-place assembly and is standard for high-volume manufacturing of BZW04-15HE3/54 in DO-41 axial packages.
How does BZW04-15HE3/54 compare to unidirectional variants like BZW04-15E3/54?
BZW04-15HE3/54 provides identical VWM (15.3 V), VBR (17.1–18.9 V), and VC (25.2 V) ratings as its unidirectional counterpart but operates in both directions. Unlike unidirectional versions with a cathode band, BZW04-15HE3/54 has no polarity marking - simplifying layout in AC-coupled or floating circuits where directionality is undefined.
What is the maximum clamping voltage of BZW04-15HE3/54 under surge conditions?
The maximum clamping voltage (VC) of BZW04-15HE3/54 is 25.2 V at 16.0 A peak pulse current (IPPM), measured with a 10/1000 μs waveform. This value represents the upper limit of voltage imposed on protected circuitry during worst-case transient events, ensuring compatibility with 3.3 V and 5 V logic families.
