Product details
Overview
BZW04-13B-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for robust overvoltage protection of signal and power lines. It features a 12.8 V stand-off voltage (VWM), 14.3–15.8 V breakdown voltage (VBR) at 1 mA test current, 21.2 V clamping voltage (VC) at 19.0 A peak pulse current (IPPM), and 400 W peak pulse power (PPPM) with 10/1000 μs waveform - suitable for protecting automotive sensor interfaces and industrial I/O circuits against ESD and inductive switching transients.
For engineers reviewing the BZW04-13B-E3/54 datasheet, BZW04-13B-E3/54 pinout, BZW04-13B-E3/54 application, or BZW04-13B-E3/54 equivalent, this device is evaluated for bidirectional surge suppression in DC power rails, analog sensor inputs, and low-speed communication lines where fast response (<1 ns), low clamping ratio, and AEC-Q101 qualification are required.
Technical Context
The BZW04-13B-E3/54 employs a glass-passivated silicon junction optimized for bidirectional transient suppression without polarity marking. Its 10/1000 μs waveform rating supports repetitive surge events at 0.01% duty cycle, and it maintains stable clamping performance across -55 °C to +175 °C operating junction temperature.
It delivers 21.2 V clamping at 19.0 A peak pulse current with <1.0 μA reverse leakage at 12.8 V stand-off, enabling reliable protection of 12 V nominal systems. The device meets AEC-Q101 stress testing requirements and exhibits a +0.084 %/°C temperature coefficient of VBR, ensuring predictable voltage drift under thermal variation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 12.8 V - maximum continuous reverse working voltage before conduction begins; defines safe operating margin for 12 V rail protection. |
| VBR min/max | 14.3 V / 15.8 V at 1 mA - verified breakdown threshold ensures consistent turn-on behavior across production lots. |
| VC @ IPPM | 21.2 V at 19.0 A - clamping voltage during 10/1000 μs surge; limits downstream voltage stress to ≤21.2 V under worst-case transient. |
| PPPM | 400 W - peak pulse power handling capability with standard 10/1000 μs waveform; supports high-energy transients per IEC 61000-4-5. |
| ID @ VWM | <1.0 μA - ultra-low reverse leakage preserves signal integrity and minimizes standby power loss in always-on circuits. |
| TJ max | +175 °C - extended junction temperature rating enables use in under-hood automotive and high-ambient industrial environments. |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including HTOL, TC, and ESD testing per AEC specification. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional transient path | No defined anode/cathode; terminals interchangeable - enables placement without orientation check on PCB. |
| Lead 1 / Lead 2 | Surge current entry/exit points | Both leads conduct equally in either direction during clamping; requires no directional routing in layout. |
Key Features

| DO-41 package with RoHS-compliant E3 suffix | Industry-standard through-hole footprint compatible with legacy and new designs; meets JESD201 Class 1A whisker resistance. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus nodes and analog sensor outputs (e.g., pressure, temperature) from load dump and ESD in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional TVS clamp placed directly at connector or IC input pins to shunt transients before reaching sensitive analog front-ends or transceivers. Use Value: Limits induced voltage to ≤21.2 V during 19 A surges, preventing latch-up or damage to 12 V-rated microcontrollers and signal conditioners. |
Use Scenario: Safeguarding digital input/output channels on programmable logic controllers exposed to relay coil kickback and motor drive noise. IC Role / Device Role / Timing Role: Standoff protection element on 24 V DC I/O lines, operating continuously at 24 V nominal with transient suppression during field wiring faults. Use Value: Withstands 400 W pulses while maintaining <1.0 μA leakage - avoids false triggering and preserves signal fidelity in high-noise factory environments. |
| Consumer Power Adapter Input | Telecom Line Interface Protection |
Use Scenario: Secondary-side overvoltage protection in AC/DC adapters and USB PD chargers subjected to lightning-induced surges on DC output lines. IC Role / Device Role / Timing Role: Final-stage clamping device after primary regulation, absorbing residual transients that bypass upstream filtering. Use Value: Fast sub-nanosecond response and 21.2 V clamping prevent overvoltage stress on downstream USB-C controller ICs rated for 20 V absolute maximum. |
Use Scenario: Protection of RS-232/RS-485 transceivers and modem line drivers connected to unshielded telephone wiring in building automation systems. IC Role / Device Role / Timing Role: Bidirectional surge suppressor placed between transceiver pins and external connectors to divert common-mode and differential transients. Use Value: Symmetrical clamping ensures equal protection for both signal polarities - essential for full-duplex serial interfaces without polarity constraints. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13CA | DO-214AA (SMB) surface-mount package; same 13 V nominal VWM but higher 24.4 V clamping at 17.6 A; 600 W PPPM rating. | Requires PCB rework for SMT vs. through-hole; better suited for space-constrained consumer electronics rather than legacy industrial boards. | Select SMBJ13CA only when board real estate is limited and SMT assembly is available; not drop-in compatible with BZW04-13B-E3/54 footprint. |
| P6KE13CA | DO-15 package; identical 13 V VWM and bidirectional function but lower 400 W rating derated above 25 °C; no AEC-Q101 qualification. | Lacks automotive qualification and has reduced thermal derating - acceptable for commercial-grade industrial equipment but not automotive Tier-1 designs. | Choose P6KE13CA for cost-sensitive non-automotive applications where AEC-Q101 is not mandated and thermal margins are sufficient. |
Compared with SMBJ13CA and P6KE13CA, the BZW04-13B-E3/54 provides through-hole manufacturability, AEC-Q101 validation, and DO-41 compatibility with existing tooling - making it optimal for automotive and industrial upgrades requiring zero layout change and certified reliability.

FAQ
What is the clamping voltage of BZW04-13B-E3/54 under a 10/1000 μs surge?
The BZW04-13B-E3/54 clamps to a maximum of 21.2 V at 19.0 A peak pulse current (IPPM) when subjected to a 10/1000 μs waveform. This value is measured per IEC 61000-4-5 test conditions and represents the upper limit of voltage seen by protected circuitry during standardized surge events - a key parameter for ensuring downstream ICs remain within their absolute maximum ratings.
Is BZW04-13B-E3/54 suitable for automotive applications?
Yes, BZW04-13B-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use. Its DO-41 package, 175 °C maximum junction temperature, and validation across HTOL, temperature cycling, and ESD tests confirm suitability for engine control units, body electronics, and ADAS sensor interfaces where reliability under thermal and mechanical stress is mandatory.
Does BZW04-13B-E3/54 have polarity markings?
No, BZW04-13B-E3/54 is a bidirectional TVS diode and carries no polarity marking on the DO-41 package. Both leads are functionally identical, allowing unrestricted orientation during manual or automated insertion - a design advantage for simplifying assembly and eliminating orientation-related defects in through-hole manufacturing.
What is the maximum reverse leakage current for BZW04-13B-E3/54 at its stand-off voltage?
At its 12.8 V stand-off voltage (VWM), the BZW04-13B-E3/54 exhibits a maximum reverse leakage current (ID) of 1.0 μA at 25 °C. This ultra-low leakage preserves signal integrity in high-impedance sensor paths and minimizes quiescent power loss in battery-powered or energy-efficient systems.
How does the temperature coefficient affect BZW04-13B-E3/54's breakdown voltage?
The BZW04-13B-E3/54 has a maximum temperature coefficient of +0.084 %/°C for its breakdown voltage (VBR). This means VBR increases by approximately 12 mV per °C rise above 25 °C - a predictable, linear drift that allows designers to maintain safe margins across the full -55 °C to +175 °C operating range without unexpected conduction onset.
