Product details
Overview
BZW04P5V8BHE3/73 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 5.8 V standoff voltage (VWM), 400 W peak pulse power (10/1000 µs), clamping voltage of 10.5 V at 38 A, and AEC-Q101 qualification - making it suitable for automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the BZW04P5V8BHE3/73 datasheet, BZW04P5V8BHE3/73 pinout, BZW04P5V8BHE3/73 application, or BZW04P5V8BHE3/73 equivalent, key selection criteria include its bi-directional symmetry, low clamping ratio (VC/VWM = 1.81), DO-204AL (DO-41) through-hole package, and compliance with automotive reliability standards.
Technical Context
This bi-directional TVS diode operates symmetrically in both polarities, with breakdown voltage (VBR) specified at 6.45–7.48 V (min/max) under 10 mA test current. Its junction exhibits glass passivation for stable surge performance and low incremental surge resistance, enabling fast response (<1 ns) to ESD and lightning-induced transients.
The device sustains repetitive 400 W pulses (10/1000 µs, 0.01% duty cycle) and handles up to 1000 µA reverse leakage at VWM. Thermal operation spans −55 °C to +175 °C, with power derating above 25 °C per Figure 2 and lead temperature limits of 275 °C for 10 s during solder dip.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.8 V - maximum continuous reverse operating voltage before clamping begins; defines safe working margin for 5 V logic/sensor rails. |
| VC @ IPPM | 10.5 V at 38 A - clamped voltage during 400 W transient; ensures downstream ICs (e.g., MCU GPIO, CAN transceivers) remain below absolute max ratings. |
| PPPM | 400 W - peak pulse power handling capability with 10/1000 µs waveform; meets IEC 61000-4-5 Level 4 surge immunity requirements. |
| IPPM | 38 A - peak pulse current corresponding to 400 W clamping; validates protection against 2 Ω source impedance surges. |
| TJ max | +175 °C - maximum junction temperature; supports under-hood automotive placement and high-ambient industrial environments. |
| AEC-Q101 | Qualified - certified for automotive-grade reliability including HTOL, temperature cycling, and ESD testing per stress test plan. |
| Package | DO-204AL (DO-41) - standard axial-leaded through-hole package with matte tin-plated leads, UL 94 V-0 molded epoxy body. |
Pinout & Package
DO-204AL (DO-41) package: axial-leaded, cylindrical epoxy-molded case with no polarity marking for bi-directional operation. Leads are matte tin-plated, solderable per J-STD-002 and JESD22-B102, rated for 275 °C / 10 s solder dip.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bi-directional avalanche junction | No functional distinction between leads; either terminal serves as cathode or anode depending on transient polarity - enables single-component protection of AC or floating DC lines. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling and humidity exposure. |
| 400 W peak pulse power (10/1000 µs) | Provides robust defense against IEC 61000-4-5 combination wave surges up to 4 kV (2 Ω source). |
| AEC-Q101 qualification | Validates suitability for automotive applications including engine control modules, body electronics, and ADAS sensor interfaces. |
| Low clamping ratio (VC/VWM = 1.81) | Minimizes protected circuit overvoltage stress while maintaining tight VWM margin for 5 V systems. |
| RoHS-compliant HE3 suffix | Indicates AEC-Q101 qualified, whisker-tested (JESD201 Class 2), and compliant with EU Directive 2011/65/EU. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0A-E3/52 | Uni-directional; 5.0 V VWM, 600 W PPPM, SMC package (surface-mount) | Requires polarity-aware layout; better suited for PCB space-constrained DC power rail protection. | Select when higher peak power and automated assembly are prioritized over bi-directional symmetry and through-hole mounting. |
| 1.5KE6.8A | Uni-directional; 6.8 V VWM, 1500 W PPPM, DO-201 package (larger axial) | Higher clamping (11.5 V) and lower VWM margin; used in legacy industrial power supply inputs. | Choose for legacy designs needing higher surge rating and compatibility with existing DO-201 footprints - not drop-in for BZW04P5V8BHE3/73. |
Compared with SMBJ5.0A-E3/52 and 1.5KE6.8A, BZW04P5V8BHE3/73 uniquely combines bi-directional operation, AEC-Q101 qualification, and DO-41 through-hole robustness - making it optimal for new automotive and high-reliability industrial designs where polarity-agnostic protection and mechanical retention are critical.

FAQ
What is the meaning of the 'HE3' suffix in BZW04P5V8BHE3/73?
The HE3 suffix in BZW04P5V8BHE3/73 indicates RoHS-compliant construction with AEC-Q101 qualification and JESD201 Class 2 whisker resistance. It distinguishes this automotive-grade variant from commercial-grade E3 versions and confirms compliance with automotive reliability stress tests including high-temperature operating life and temperature cycling.
Is BZW04P5V8BHE3/73 suitable for protecting USB 2.0 data lines?
Yes, BZW04P5V8BHE3/73 is suitable for secondary-level USB 2.0 D+/D− protection due to its bi-directional symmetry, sub-ns response time, and low 0.45 pF typical junction capacitance at zero bias. Its 5.8 V VWM provides adequate margin above 3.3 V signaling levels while clamping transients to 10.5 V - well within USB transceiver absolute maximum ratings.
How does the clamping voltage of BZW04P5V8BHE3/73 compare to its standoff voltage?
BZW04P5V8BHE3/73 has a standoff voltage (VWM) of 5.8 V and a maximum clamping voltage (VC) of 10.5 V at 38 A, yielding a clamping ratio of 1.81. This tight ratio ensures protected circuits experience minimal overvoltage stress during surge events - critical for safeguarding 5 V logic interfaces and analog front-ends without compromising signal fidelity.
Can BZW04P5V8BHE3/73 be used in place of a uni-directional TVS like BZW04P5V8HE3/73?
No - BZW04P5V8BHE3/73 is bi-directional (denoted by the 'B' suffix) and lacks polarity marking, whereas BZW04P5V8HE3/73 is uni-directional with a cathode band. Substituting them requires verifying circuit topology: bi-directional use is mandatory for AC-coupled or floating lines; uni-directional parts are required where forward conduction must be blocked in one direction.
What is the maximum allowable lead temperature during soldering for BZW04P5V8BHE3/73?
The maximum allowable lead temperature for BZW04P5V8BHE3/73 is 275 °C for up to 10 seconds, per JESD 22-B106. This specification supports wave soldering and hand-soldering processes while preserving junction integrity and glass passivation stability - essential for maintaining long-term surge performance in automotive and industrial assemblies.
