Product details
Overview
BZW04P13-E3/73 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 13 V standoff voltage (VWM), 400 W peak pulse power rating (10/1000 μs), and clamps transients to ≤21.2 V at 19 A, making it suitable for protecting MOSFETs, sensor interfaces, and industrial control inputs against inductive switching surges.
For engineers reviewing the BZW04P13-E3/73 datasheet, BZW04P13-E3/73 pinout, BZW04P13-E3/73 application, or BZW04P13-E3/73 equivalent, key selection criteria include its DO-41 package compatibility, AEC-Q101 qualification status, bi-directional clamping symmetry, low leakage (<1 μA at 12.8 V), and temperature coefficient of breakdown voltage (0.084 %/°C).
Technical Context
This device operates as a voltage-clamped shunt protector with symmetrical bi-directional avalanche breakdown behavior-no polarity marking required. Its glass-passivated junction ensures stable performance under repetitive surge conditions, while the 10/1000 μs waveform rating reflects standardized IEC 61000-4-5 surge immunity testing compliance.
The BZW04P13-E3/73 delivers consistent clamping across -55 °C to +175 °C operating junction temperature, with thermal derating governed by Fig. 2 in the datasheet. Its 1.5 W steady-state power dissipation (PD) and 175 °C max TJ enable reliable operation in high-ambient industrial environments without active cooling.
Key Specifications

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) package; 600 W PPPM; slightly higher VC (21.5 V @ 22.5 A); same VWM (13 V) | Higher power density but requires surface-mount layout; less suited for through-hole repair or high-voltage creepage designs | Choose SMBJ13CA when board space is constrained and SMT assembly is standard; verify PCB creepage meets IEC 61000-4-5 requirements. |
| P6KE13CA | DO-15 package; 600 W PPPM; higher VC (23.2 V @ 26 A); wider VBR tolerance (13.3–15.8 V) | Legacy through-hole alternative with lower surge current density and looser voltage tolerance | Prefer P6KE13CA only for legacy design refreshes where DO-15 footprint reuse is mandatory; BZW04P13-E3/73 offers tighter VBR and lower VC. |
Compared with SMBJ13CA and P6KE13CA, the BZW04P13-E3/73 provides superior voltage tightness (VBR 14.3–16.5 V vs. ±10 %), lower clamping (21.2 V vs. ≥21.5 V), and AEC-Q101 qualification-making it the preferred choice for new automotive and industrial designs requiring high-reliability through-hole TVS protection.

FAQ
What is the maximum clamping voltage of the BZW04P13-E3/73 under surge conditions?
The BZW04P13-E3/73 clamps to a maximum of 21.2 V when subjected to its rated peak pulse current of 19 A (10/1000 μs waveform). This value is guaranteed across the full operating temperature range and forms the basis for downstream circuit voltage margining in designs using the BZW04P13-E3/73.
Is the BZW04P13-E3/73 suitable for automotive applications?
Yes-the BZW04P13-E3/73 carries AEC-Q101 qualification (HE3 suffix variant), confirming compliance with automotive reliability stress tests including temperature cycling, humidity bias, and mechanical shock. Its 175 °C max junction temperature and bi-directional symmetry make it appropriate for engine control, body electronics, and sensor interface protection in vehicles.
Does the BZW04P13-E3/73 have polarity markings?
No-BZW04P13-E3/73 is a bi-directional TVS diode and carries no cathode band or polarity marking. Both terminals are functionally identical, enabling flexible placement on AC-coupled lines, differential buses, or unidirectional rails where reverse polarity risk exists.
What is the standoff voltage (VWM) rating for the BZW04P13-E3/73?
The BZW04P13-E3/73 has a maximum working standoff voltage (VWM) of 12.8 V. This is the highest DC or RMS voltage that can be continuously applied without triggering significant conduction-ensuring minimal leakage (<1 μA) during normal operation while preserving headroom before clamping initiates.
How does the BZW04P13-E3/73 compare to older P6KE-series TVS diodes?
The BZW04P13-E3/73 offers tighter breakdown voltage tolerance (14.3–16.5 V vs. ±10 %), lower clamping voltage (21.2 V vs. 23.2 V), and AEC-Q101 qualification-unlike most P6KE variants. Its DO-41 package maintains through-hole compatibility while delivering improved surge response and thermal robustness for modern industrial and automotive designs using the BZW04P13-E3/73.
