Product details
Overview
BZW04P15BHE3/54 from Vishay General Semiconductor is a bi-directional TransZorb® transient voltage suppressor (TVS) diode designed for robust overvoltage protection in signal and power lines. It features a 15.3 V stand-off voltage (VWM), 25.2 V clamping voltage (VC) at 16.0 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive sensor interfaces, industrial I/O protection, and telecom line surge suppression.
For engineers reviewing the BZW04P15BHE3/54 datasheet, BZW04P15BHE3/54 pinout, BZW04P15BHE3/54 application, or BZW04P15BHE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, DO-204AL (DO-41) package, bi-directional symmetry, low clamping ratio (VC/VWM = 1.65), and 0.088 %/°C breakdown voltage temperature coefficient - critical for stable protection across automotive temperature ranges.
Technical Context
This bi-directional TVS operates symmetrically in both polarities, with identical electrical characteristics forward and reverse - enabling single-device protection of AC-coupled or floating signal paths without polarity concerns. Its glass-passivated junction ensures stable leakage performance and fast response (<1 ns), while the 10/1000 µs pulse rating reflects standardized surge immunity per ANSI/IEEE C62.35.
The device is rated for 175 °C maximum junction temperature and derates linearly above 25 °C ambient, supporting operation in under-hood automotive environments. Its 1.5 W steady-state power dissipation (PD) and 1.0 mA test current (IT) define its DC bias stability, and the 0.088 %/°C VBR temperature coefficient ensures predictable breakdown drift across temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 15.3 V - Maximum continuous working voltage before clamping begins; defines safe operating margin for 12 V nominal systems. |
| VC @ IPPM | 25.2 V at 16.0 A - Clamping voltage during 10/1000 µs surge; limits downstream voltage stress to ≤25.2 V under worst-case transient. |
| PPPM | 400 W - Peak pulse power handling capability; supports IEC 61000-4-5 Level 3 (1 kV/2 Ω) surge compliance when properly routed. |
| VBR min/max | 17.1 V / 19.8 V at 1.0 mA - Breakdown voltage range; guarantees activation within tight tolerance, enabling precise system-level protection coordination. |
| ID @ VWM | 1.0 µA - Reverse leakage at stand-off voltage; negligible power loss and no measurable loading on 15 V bias rails. |
| TJ max | 175 °C - Maximum junction temperature; enables use in AEC-Q101 automotive applications including engine control and body electronics. |
| Package | DO-204AL (DO-41) - Standard axial-leaded through-hole package; compatible with legacy PCB layouts and wave-solder processes. |
Pinout & Package
DO-204AL (DO-41) package: axial-leaded, molded epoxy case with matte tin-plated leads; no polarity marking for bi-directional operation - either lead may serve as anode or cathode depending on transient polarity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bi-directional surge conduction path | Both terminals function identically - conducts clamp current in either direction upon exceeding VBR; no orientation required during placement. |
| Case | Non-connected mechanical structure | Epoxy-molded body provides mechanical integrity and UL 94 V-0 flammability rating; no thermal or electrical connection to die. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including HTOL, TC, and ESD testing - suitable for safety-critical vehicle subsystems. |
| Glass passivated junction | Ensures stable leakage current and long-term parameter consistency across humidity and thermal cycling stress. |
| 400 W peak pulse power (10/1000 µs) | Withstands repetitive surges up to 0.01 % duty cycle - sufficient for CAN bus, LIN, and sensor supply line protection per ISO 7637-2. |
| Low clamping ratio (VC/VWM = 1.65) | Minimizes overvoltage overshoot during transients - protects 16 V tolerant ICs (e.g., automotive MCUs) without external series impedance. |
| RoHS-compliant & whisker-tested (JESD201 Class 2) | HE3 suffix confirms AEC-Q101 qualification and Class 2 tin whisker resistance - meets automotive manufacturing and field-reliability requirements. |

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 | Same VWM (15.0 V) and VC (24.4 V), but SMC (DO-214AB) surface-mount package; 600 W PPPM rating. | Requires PCB redesign for SMD layout; better suited for high-density consumer electronics than through-hole industrial modules. | Select SMBJ15CA only if board space constraints mandate SMD and higher surge margin is needed. |
| P6KE15CA | Legacy 600 W TVS in DO-15 package; VWM = 12.8 V, VC = 24.4 V; no AEC-Q101 qualification; higher leakage (5.0 µA). | Lacks automotive qualification and exhibits wider VBR tolerance (14.3–15.8 V); less precise coordination with downstream IC thresholds. | Choose P6KE15CA only for cost-sensitive commercial applications where AEC-Q101 and tight VBR are not required. |
Compared with SMBJ15CA and P6KE15CA, BZW04P15BHE3/54 offers AEC-Q101 qualification, tighter VBR tolerance (17.1–19.8 V), lower leakage (1.0 µA), and DO-41 compatibility - making it the preferred choice for automotive and industrial through-hole designs requiring certified reliability and precise clamping.

FAQ
What is the clamping voltage of BZW04P15BHE3/54 under a 10/1000 µs surge?
The BZW04P15BHE3/54 has a maximum clamping voltage (VC) of 25.2 V at 16.0 A peak pulse current with a 10/1000 µs waveform. This value is guaranteed per the Vishay datasheet (Document Number: 88316) and defines the upper voltage limit imposed on protected circuitry during standardized surge events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is BZW04P15BHE3/54 suitable for automotive applications?
Yes, BZW04P15BHE3/54 is AEC-Q101 qualified (HE3 suffix) and rated for −55 °C to +175 °C junction temperature operation. Its glass-passivated junction, low leakage (1.0 µA), and stable clamping behavior make it appropriate for automotive sensor interfaces, body control modules, and infotainment power rails where reliability under thermal and electrical stress is mandatory.
Does BZW04P15BHE3/54 have polarity markings?
No, BZW04P15BHE3/54 is a bi-directional TVS diode and carries no polarity marking on the DO-204AL (DO-41) package. Its symmetrical construction means either lead functions identically - eliminating orientation concerns during manual or automated assembly and simplifying layout for AC or floating signal paths.
What is the standoff voltage (VWM) and why does it matter for BZW04P15BHE3/54?
The standoff voltage (VWM) of BZW04P15BHE3/54 is 15.3 V - the maximum continuous DC or RMS voltage the device tolerates without entering conduction. This parameter ensures the TVS remains non-conductive during normal operation (e.g., on a 12 V automotive rail with ripple), preventing power loss or interference while still triggering reliably during overvoltage events exceeding ~17.1 V.
How does the temperature coefficient affect BZW04P15BHE3/54 performance?
The BZW04P15BHE3/54 has a maximum breakdown voltage temperature coefficient of 0.088 %/°C. This means VBR increases by up to 0.088 % per degree Celsius rise in junction temperature - resulting in a ~1.7 V increase from −40 °C to +125 °C. Designers must account for this drift when coordinating with downstream IC overvoltage thresholds across the full operating range.
