Product details
Overview
BZW04P136-E3/54 from Vishay General Semiconductor is a bi-directional TransZorb® transient voltage suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 136 V standoff voltage (VWM), 219 V clamping voltage (VC) at 1.8 A peak pulse current (IPPM), and 400 W peak pulse power (10/1000 µs waveform), making it suitable for protecting MOSFETs, sensor interfaces, and industrial control inputs against lightning-induced surges and inductive switching transients.
For engineers reviewing the BZW04P136-E3/54 datasheet, BZW04P136-E3/54 pinout, BZW04P136-E3/54 application, or BZW04P136-E3/54 equivalent, key selection considerations include its DO-204AL (DO-41) axial package, AEC-Q101 qualification, 175 °C maximum junction temperature, and bi-directional clamping behavior essential for AC-coupled or floating-line protection schemes.
Technical Context
This device operates as a voltage-clamped avalanche diode with symmetrical breakdown characteristics in both polarities, enabling protection of bidirectional signal paths without polarity constraints. Its glass-passivated junction ensures stable leakage performance and low incremental surge resistance, critical for consistent clamping under repetitive transients.
The BZW04P136-E3/54 delivers 400 W peak pulse power handling per the 10/1000 µs standard waveform, with thermal derating above 25 °C ambient per Figure 2 and junction temperature limits up to 175 °C - supporting reliable operation in automotive under-hood and industrial environments where thermal stress is significant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 136 V - Maximum continuous reverse voltage before clamping begins; defines operating margin below breakdown. |
| VC (Clamping Voltage) | 219 V at 1.8 A IPPM - Peak voltage seen by protected circuit during specified surge; determines safe voltage ceiling. |
| IPPM (Peak Pulse Current) | 1.8 A (10/1000 µs) - Maximum transient current the device safely shunts without degradation. |
| PPPM (Peak Pulse Power) | 400 W - Surge energy-handling capability under standardized waveform; enables compliance with IEC 61000-4-5 Level 3. |
| TJmax | 175 °C - Maximum junction temperature; supports extended operation in high-ambient industrial and automotive applications. |
| VBR (Breakdown Voltage) | 152–176 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on within design tolerance. |
| Leakage Current (ID) | ≤1.0 µA at VWM - Ultra-low reverse leakage preserves signal integrity and minimizes standby power loss. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130CA | DO-214AA package (SMB), 130 V VWM, 219 V VC at 1.8 A, same PPPM | Surface-mount footprint; lower thermal mass than axial DO-41; less suited for high-reliability through-hole assemblies. | Select when board space is constrained and reflow compatibility is required. |
| 1.5KE150CA | DO-201AD package, 150 V VWM, 243 V VC at 1.65 A, 1500 W PPPM | Higher power rating but larger size and higher clamping voltage; not AEC-Q101 qualified. | Choose only for non-automotive applications requiring >400 W surge handling and where 243 V clamping is acceptable. |
Compared with SMBJ130CA and 1.5KE150CA, the BZW04P136-E3/54 offers AEC-Q101 qualification, tighter VWM/VC matching (136 V / 219 V), and proven reliability in axial through-hole mounting - making it optimal for automotive and industrial designs demanding long-term mechanical stability and traceable qualification.

FAQ
What is the clamping voltage of BZW04P136-E3/54 under a 10/1000 µs surge?
The BZW04P136-E3/54 has a maximum clamping voltage (VC) of 219 V at 1.8 A peak pulse current (IPPM) under the standardized 10/1000 µs waveform. This value is measured per IEC 61000-4-5 test conditions and defines the upper voltage limit imposed on protected circuits during surge events. The BZW04P136-E3/54 maintains this clamping performance across its rated junction temperature range.
Is BZW04P136-E3/54 suitable for automotive applications?
Yes, BZW04P136-E3/54 is AEC-Q101 qualified, confirming its reliability for automotive use in engine control units, body electronics, and sensor modules. Its 175 °C maximum junction temperature, glass-passivated junction, and validated surge endurance meet stringent automotive environmental and lifetime requirements. The BZW04P136-E3/54 is explicitly listed in Vishay's AEC-Q101 qualified devices table.
What does the "E3/54" suffix mean in BZW04P136-E3/54?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction with JESD201 Class 1A whisker resistance; "54" is the preferred package code indicating 13-inch paper tape and reel packaging with 550 units per reel. This format ensures compatibility with automated SMT placement equipment despite the device being axial-leaded. The BZW04P136-E3/54 uses matte tin-plated leads solderable per J-STD-002.
How does BZW04P136-E3/54 differ from uni-directional variants like BZW04-136?
The BZW04P136-E3/54 is bi-directional (denoted by "B" in part number variants), providing symmetrical clamping for both positive and negative transients - ideal for AC lines or floating signals. Uni-directional BZW04-136 has a cathode band and only clamps in reverse bias; forward conduction follows standard diode behavior. The BZW04P136-E3/54 eliminates polarity marking and layout constraints inherent to uni-directional types.
What is the maximum operating temperature for BZW04P136-E3/54?
The BZW04P136-E3/54 has an operating junction temperature range of –55 °C to +175 °C, with thermal derating applied above 25 °C ambient per Figure 2 in the datasheet. Its DO-204AL package allows direct lead-to-heatsink mounting for enhanced thermal dissipation in high-power transient scenarios. The BZW04P136-E3/54 retains full 400 W PPPM capability up to 25 °C ambient, then linearly derates to zero at 175 °C junction temperature.
