Product details
Overview
BZW04P11-E3/54 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 11.1 V stand-off voltage (VWM), 12.4–14.3 V breakdown voltage (VBR) at 1 mA, 18.2 V clamping voltage (VC) at 22 A peak pulse current, and 400 W peak pulse power capability with 10/1000 µs waveform - ideal for safeguarding MOSFETs and sensor interfaces against inductive switching transients.
For engineers reviewing the BZW04P11-E3/54 datasheet, BZW04P11-E3/54 pinout, BZW04P11-E3/54 application, or BZW04P11-E3/54 equivalent, key selection criteria include its DO-204AL (DO-41) axial package, bi-directional symmetry, AEC-Q101 qualification, low 1.0 µA reverse leakage at VWM, and suitability for automotive and industrial board-level ESD/surge protection where bidirectional clamping without polarity constraints is required.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ) up to 11.1 V, then rapidly avalanches to limit transient voltages to ≤18.2 V at 22 A. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), while the bi-directional structure eliminates polarity dependency in AC-coupled or floating lines.
The BZW04P11-E3/54 is rated for 175 °C maximum junction temperature and derates linearly above 25 °C ambient per Vishay's Fig. 2 curve. Its 1.5 W steady-state power dissipation (PD) and 400 W non-repetitive peak pulse power (PPPM) support both infrequent surge events and sustained overvoltage conditions within thermal limits when mounted on standard PCB copper.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 11.1 V - Maximum continuous reverse working voltage before significant leakage; defines safe operating margin below clamping threshold. |
| VBR (min/max) | 12.4 V / 14.3 V at 1 mA - Confirmed avalanche onset range; ensures reliable triggering across process variation and temperature. |
| VC @ IPPM | 18.2 V at 22 A - Clamped voltage during 10/1000 µs surge; directly determines protected circuit's maximum transient stress level. |
| PPPM | 400 W - Peak pulse power handling with 10/1000 µs waveform; enables suppression of high-energy transients like ISO 7637-2 Pulse 1/2a/5a. |
| ID @ VWM | 1.0 µA - Reverse leakage current at stand-off voltage; low value minimizes standby power loss and avoids false triggering. |
| TJ max. | 175 °C - Maximum junction temperature rating; supports operation in under-hood automotive and industrial environments. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD47. |
Pinout & Package
Package: DO-204AL (DO-41), axial leaded, epoxy-molded case meeting UL 94 V-0 flammability rating. Matte tin-plated leads compliant with J-STD-002 and JESD22-B102 solderability standards. No polarity marking - bi-directional symmetry confirmed.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bi-directional avalanche junction terminals | No functional distinction; either end connects to protected line or ground - enables placement without orientation check. |
Key Features
| Feature | Design Value |

| RoHS-compliant, matte tin leads | Enables lead-free reflow assembly and meets global environmental compliance requirements without whisker risk (JESD201 Class 1A). |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ11CA | Same DO-214AA (SMB) package; 11 V VWM, 18.2 V VC @ 21.4 A; higher 600 W PPPM but larger footprint. | Preferred where board space allows SMB package and higher surge margin is needed (e.g., outdoor telecom). | Select SMBJ11CA if layout accommodates surface-mount and 600 W rating is required; not drop-in due to package mismatch. |
| P6KE11CA | DO-15 package; 11 V VWM, 19.5 V VC @ 18.5 A; 600 W PPPM, lower cost but longer lead time and no AEC-Q101 qualification. | Suitable for cost-sensitive industrial power supplies where automotive qualification is unnecessary. | Choose P6KE11CA for non-automotive applications requiring higher energy rating and legacy through-hole compatibility. |
Compared with BZW04P11-E3/54, SMBJ11CA offers higher surge capacity in a surface-mount package but requires PCB redesign, while P6KE11CA provides greater pulse power in a pin-compatible axial form but lacks AEC-Q101 validation and has looser parameter tolerances - making BZW04P11-E3/54 the optimal choice for space-constrained, automotive-qualified designs needing proven bi-directional clamping in DO-41.

FAQ
What is the polarity configuration of BZW04P11-E3/54?
BZW04P11-E3/54 is a bi-directional TVS diode with symmetrical anode/cathode terminals and no polarity marking. This allows installation in either orientation on AC-coupled or floating signal lines, simplifying layout and eliminating orientation errors during assembly - a key advantage over uni-directional variants like BZW04P11.
Does BZW04P11-E3/54 meet automotive qualification standards?
Yes, BZW04P11-E3/54 is AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD per JESD22-A114. This certification confirms its suitability for under-hood and cabin electronics in passenger vehicles and commercial vehicles where reliability under thermal and electrical stress is mandatory.
What is the maximum clamping voltage of BZW04P11-E3/54 during a surge event?
The maximum clamping voltage (VC) of BZW04P11-E3/54 is 18.2 V at a peak pulse current (IPPM) of 22 A with a 10/1000 µs waveform. This value represents the upper limit of voltage seen by downstream circuitry during worst-case transient events, ensuring protected ICs remain within their absolute maximum ratings.
Can BZW04P11-E3/54 be used in place of a uni-directional TVS diode?
BZW04P11-E3/54 can replace a uni-directional TVS only if the circuit topology supports bi-directional clamping - such as across AC lines, differential pairs, or floating grounds. It must not be substituted in DC-biased unidirectional paths (e.g., VCC-to-ground) without verifying that reverse conduction does not disrupt bias conditions or cause unintended current paths in the BZW04P11-E3/54 application.
What packaging format is supplied for BZW04P11-E3/54?
BZW04P11-E3/54 is supplied in 13-inch diameter paper tape and reel packaging (package code "54"), with 550 units per reel. The "E3" suffix indicates RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting J-STD-002 solderability and JESD201 Class 1A whisker resistance requirements.
