Product details
Overview
BZW04P15-E3/54 from Vishay General Semiconductor is a bi-directional TransZorb® transient voltage suppressor (TVS) diode designed for robust overvoltage protection on 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 and industrial I/O protection.
For engineers reviewing the BZW04P15-E3/54 datasheet, BZW04P15-E3/54 pinout, BZW04P15-E3/54 application, or BZW04P15-E3/54 equivalent, key selection criteria include its DO-41 package compatibility, AEC-Q101 qualification, bi-directional surge handling up to 16.0 A, and low 0.088 %/°C breakdown voltage temperature coefficient - critical for stable clamping across automotive temperature ranges.
Technical Context
This bi-directional TVS diode operates symmetrically in both polarities, enabling protection of AC-coupled or floating signal paths without polarity constraints. Its glass-passivated junction ensures stable leakage performance and fast response (<1 ns) to ESD and lightning-induced transients.
The device sustains repetitive 400 W pulses at 0.01 % duty cycle and derates linearly above 25 °C ambient per Fig. 2; maximum junction temperature is rated at +175 °C, supporting under-hood automotive deployment. Clamping behavior is validated per ANSI/IEEE C62.35 standards using the defined 10/1000 µs waveform.
Key Specifications

|---|---|
| VWM | 15.3 V - Maximum continuous reverse working voltage before clamping initiates; defines safe operating margin below breakdown. |
| VBR (min/max) | 17.1 V / 19.8 V at 1.0 mA - Verified breakdown range ensures consistent turn-on across production lots and temperature. |
| VC @ IPPM | 25.2 V at 16.0 A - Measured clamping voltage limits downstream IC stress during 10/1000 µs surges. |
| PPPM | 400 W - Peak pulse power handling capability with standardized 10/1000 µs waveform; supports IEC 61000-4-5 Level 4 compliance. |
| IPPM | 16.0 A - Peak pulse current derived from VC and PPPM; used to size series impedance for targeted let-through energy. |
| TJ max. | +175 °C - Maximum junction temperature enables operation in high-ambient environments such as engine control units. |

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 (15.3 V) and VC (24.4 V), but SMC package (higher thermal mass); 600 W PPPM. | Higher power handling suits higher-energy surges; larger footprint requires PCB redesign. | Select when surge energy exceeds 400 W or board space permits SMC package. |
| 1.5KE15CA | Same DO-41 package and bi-directionality; lower PPPM (1500 W nominal, but 1.5 kW rating applies only to 1.0 ms pulse - not 10/1000 µs). | Not rated for repetitive 10/1000 µs surges; unsuitable for high-duty-cycle industrial environments. | Use only for infrequent, single-event protection where peak current is lower than 16 A. |

FAQ
What is the maximum clamping voltage of BZW04P15-E3/54 under standard test conditions?
The maximum clamping voltage (VC) of BZW04P15-E3/54 is 25.2 V, measured at a peak pulse current (IPPM) of 16.0 A using the standardized 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and forms the basis for downstream circuit protection design - ensuring connected ICs remain within safe voltage limits during surge events.
Is BZW04P15-E3/54 suitable for automotive applications?
Yes, BZW04P15-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use. Its +175 °C maximum junction temperature, low VBR temperature coefficient (0.088 %/°C), and robust 400 W pulse rating make it appropriate for engine control units, body electronics, and sensor interfaces exposed to load dump and ISO 7637-2 transients.
Does BZW04P15-E3/54 have polarity markings?
No, BZW04P15-E3/54 is a bi-directional TVS diode and carries no polarity marking. Its symmetrical construction allows installation in either orientation - eliminating assembly errors and simplifying layout for differential or AC-coupled signal lines where polarity is undefined.
What is the standoff voltage (VWM) specification for BZW04P15-E3/54?
The standoff voltage (VWM) for BZW04P15-E3/54 is 15.3 V - the maximum DC or RMS voltage that can be continuously applied without triggering clamping action. This value provides a 12 % margin below the minimum breakdown voltage (17.1 V), ensuring reliable non-conduction during normal operation.
How does the temperature coefficient affect BZW04P15-E3/54 performance?
The breakdown voltage temperature coefficient of BZW04P15-E3/54 is +0.088 %/°C, meaning VBR increases by approximately 0.015 V per °C rise above 25 °C. This low drift ensures predictable clamping behavior across the full -55 °C to +175 °C operating range - critical for maintaining protection margins in under-hood automotive applications.
