Product details
Overview
BZW04P15B-E3/73 from Vishay General Semiconductor is a bi-directional TransZorb® transient voltage suppressor (TVS) diode in DO-204AL (DO-41) package, designed for clamping ESD and surge transients on signal/power lines. It features 15.3 V stand-off voltage (VWM), 25.2 V maximum clamping voltage (VC) at 16.0 A peak pulse current (IPPM), 400 W peak pulse power (10/1000 µs), and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the BZW04P15B-E3/73 datasheet, BZW04P15B-E3/73 pinout, BZW04P15B-E3/73 application, or BZW04P15B-E3/73 equivalent, key selection criteria include its bi-directional clamping behavior, low 0.088 %/°C VBR temperature coefficient, 1.0 µA max reverse leakage at VWM, and suitability for protecting CAN, LIN, sensor I/O, and 12 V supply rails against ISO 7637-2 and IEC 61000-4-2 threats.
Technical Context
This bi-directional TVS operates symmetrically in both polarities with identical breakdown (17.1–19.8 V at 1.0 mA), clamping (25.2 V @ 16.0 A), and leakage characteristics. Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, critical for suppressing sub-microsecond transients induced by inductive switching or ESD events.
The device complies with AEC-Q101 stress tests and supports operation from –55 °C to +175 °C junction temperature. Its DO-204AL package provides robust mechanical mounting and meets UL 94 V-0 flammability rating, while matte tin-plated leads ensure solderability per J-STD-002 and JESD22-B102.
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 / 19.8 V at 1.0 mA - Confirmed breakdown range ensures reliable triggering across temperature and unit variation. |
| VC @ IPPM | 25.2 V at 16.0 A - Clamping voltage under 400 W 10/1000 µs surge; determines protected circuit's maximum transient overvoltage. |
| IPPM | 16.0 A - Peak pulse current capability; defines surge energy handling (400 W) without degradation. |
| Leakage (ID) | ≤1.0 µA at VWM - Ultra-low standby current preserves signal integrity and battery life in always-on systems. |
| TJ max. | +175 °C - High junction temperature rating supports under-hood automotive and industrial environments. |
| Temp. Coeff. | +0.088 %/°C - Predictable VBR drift with temperature enables stable protection across thermal extremes. |

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 bi-directional function, DO-214AA package (SMB), 15 V VWM, 24.4 V VC @ 16.3 A, 600 W PPPM | Higher power rating but larger footprint; requires PCB re-layout due to SMC/SMB pad pattern | Select when higher surge margin is needed and board space allows SMB package. |
| P6KE15CA | DO-204AC (DO-15) package, same VWM/VC, 600 W PPPM, higher IPPM (23.3 A), slower response than BZW04P15B-E3/73 | Less stringent AEC-Q101 coverage; not qualified for automotive under-hood use | Choose for cost-sensitive industrial power supplies where AEC-Q101 is not required. |

FAQ
What is the clamping voltage of BZW04P15B-E3/73 under a 10/1000 µs surge?
The BZW04P15B-E3/73 has a maximum clamping voltage (VC) of 25.2 V when subjected to its rated peak pulse current of 16.0 A using the standard 10/1000 µs waveform. This value is measured at TA = 25 °C and defines the upper voltage limit imposed on protected circuitry during transient events. The BZW04P15B-E3/73 maintains this clamping performance across its full operating temperature range.
Is BZW04P15B-E3/73 suitable for automotive applications?
Yes, BZW04P15B-E3/73 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its –55 °C to +175 °C operating junction temperature range, glass-passivated junction, and DO-204AL construction meet stringent automotive reliability requirements. The BZW04P15B-E3/73 is commonly deployed in engine control units, body control modules, and ADAS sensor interfaces.
Does BZW04P15B-E3/73 have polarity markings?
No, BZW04P15B-E3/73 is a bi-directional TVS and carries no polarity marking on its DO-204AL package body. Unlike uni-directional variants (e.g., BZW04P15-E3/73), the "B" suffix indicates symmetrical electrical characteristics in both directions-so either lead may be connected to the protected line or ground without affecting functionality. The BZW04P15B-E3/73 relies on identical VBR and VC specs for both polarities.
What is the maximum reverse leakage current for BZW04P15B-E3/73 at its stand-off voltage?
The BZW04P15B-E3/73 exhibits a maximum reverse leakage current (ID) of 1.0 µA at its rated stand-off voltage (VWM) of 15.3 V and TA = 25 °C. This ultra-low leakage ensures minimal power loss and signal distortion in always-on circuits such as automotive wake-up lines or battery-backed sensor interfaces. The BZW04P15B-E3/73 maintains tight leakage control across its full temperature range.
How does the temperature coefficient affect BZW04P15B-E3/73's breakdown voltage?
The BZW04P15B-E3/73 has a maximum temperature coefficient of +0.088 %/°C for its breakdown voltage (VBR). This means VBR increases by up to 0.088 % per degree Celsius rise in junction temperature-e.g., ~0.15 V increase from 25 °C to 175 °C. This predictable drift allows designers to maintain safe margins between VWM and VBR across operating conditions. The BZW04P15B-E3/73's coefficient is specified and tested per ANSI/IEEE C62.35.
