Product details
Overview
BZW04P5V8HE3/73 from Vishay General Semiconductor is a bi-directional TransZorb® transient voltage suppressor (TVS) diode in DO-204AL (DO-41) package, designed for clamping ESD and surge transients on signal/power lines. It features 5.8 V stand-off voltage (VWM), 10.5 V maximum clamping voltage (VC) at 38 A peak pulse current (IPPM), 400 W peak pulse power (10/1000 μs), and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the BZW04P5V8HE3/73 datasheet, BZW04P5V8HE3/73 pinout, BZW04P5V8HE3/73 application, or BZW04P5V8HE3/73 equivalent, key selection criteria include its bi-directional clamping capability, low 10.5 V VC under 38 A surge, RoHS-compliant AEC-Q101 qualification, and compatibility with inductive switching and lighting-induced transient protection in sensor interfaces and power rails.
Technical Context
This bi-directional TVS diode operates symmetrically in both polarities, with breakdown voltage (VBR) specified between 6.45 V and 7.48 V at 10 mA test current. Its clamping behavior is defined by a maximum 10.5 V VC at IPPM = 38 A (10/1000 μs waveform), enabling robust protection of downstream ICs without forward conduction during normal operation.
Thermally rated for -55 °C to +175 °C junction temperature, it delivers 1.5 W steady-state power dissipation on infinite heatsink at TL = 75 °C and withstands 40 A non-repetitive forward surge (8.3 ms half-sine) - though this applies only to uni-directional variants; BZW04P5V8HE3/73 is bi-directional and thus excludes IFSM rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.8 V - maximum continuous reverse working voltage before clamping initiates |
| VBR min/max | 6.45 V / 7.48 V at 10 mA - ensures reliable turn-on within tight tolerance band |
| VC @ IPPM | 10.5 V at 38 A (10/1000 μs) - limits transient voltage seen by protected circuitry |
| PPPM | 400 W - handles high-energy surges common in automotive load-dump and inductive switch-off |
| ID @ VWM | 1000 µA - low leakage preserves signal integrity and battery life in always-on systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0CA | DO-214AA package (SMB), 5.0 V VWM, 9.2 V VC @ 43.3 A, same 400 W PPPM | Surface-mount format; higher IPPM but slightly lower clamping voltage | Select when PCB space constraints favor SMD or thermal management requires larger pad area |
| P6KE6.8CA | DO-15 package, 6.8 V VWM, 10.5 V VC @ 36.7 A, 600 W PPPM (10/1000 μs) | Higher peak power rating but larger footprint and no AEC-Q101 qualification | Choose for cost-sensitive industrial designs where automotive qualification is not required |
Compared with BZW04P5V8HE3/73, SMBJ5.0CA offers superior board-level integration and marginally better clamping, while P6KE6.8CA trades AEC-Q101 compliance for higher surge capacity - making BZW04P5V8HE3/73 the optimal choice for automotive sensor nodes requiring proven reliability and axial-leaded serviceability.

FAQ
What is the clamping voltage of BZW04P5V8HE3/73 under maximum surge conditions?
The BZW04P5V8HE3/73 exhibits a maximum clamping voltage (VC) of 10.5 V when subjected to its rated peak pulse current of 38 A using the standard 10/1000 μs waveform. This value is measured at the device terminals and defines the upper voltage limit imposed on protected circuitry during transient events. The low VC ensures compatibility with 5 V logic families and prevents overstress of downstream ICs such as microcontrollers and transceivers.
Is BZW04P5V8HE3/73 suitable for automotive applications?
Yes, BZW04P5V8HE3/73 is AEC-Q101 qualified and explicitly rated for automotive use. Its construction includes glass-passivated junctions, matte tin-plated leads meeting JESD201 Class 2 whisker resistance, and full characterization across -55 °C to +175 °C operating temperature. The HE3 suffix confirms RoHS compliance and AEC-Q101 qualification - making BZW04P5V8HE3/73 appropriate for engine control units, body electronics, and ADAS sensor interfaces.
How does the bi-directional configuration of BZW04P5V8HE3/73 affect its circuit placement?
The bi-directional nature of BZW04P5V8HE3/73 means it conducts identically in both polarities, eliminating the need for orientation during placement. It is typically mounted between signal/power line and ground (or between differential lines), providing symmetrical protection against positive and negative transients. Unlike uni-directional TVS diodes, BZW04P5V8HE3/73 has no cathode marking - simplifying assembly and reducing risk of misorientation in high-volume manufacturing.
What is the maximum steady-state power dissipation for BZW04P5V8HE3/73?
BZW04P5V8HE3/73 has a maximum steady-state power dissipation (PD) of 1.5 W when mounted on an infinite heatsink at lead temperature (TL) of 75 °C. This rating assumes ideal thermal conduction and is derated linearly above 25 °C ambient per the published power derating curve. In typical PCB layouts without dedicated heatsinking, practical continuous power handling is limited to ~0.5–0.8 W depending on copper area and airflow.
Does BZW04P5V8HE3/73 have a specified junction capacitance?
No, the official Vishay datasheet for BZW04P5V8HE3/73 does not specify junction capacitance (CJ). While related TransZorb® devices in the same family may list CJ values (e.g., <1 pF at VWM for higher-voltage variants), BZW04P5V8HE3/73's primary design focus is high-power clamping rather than high-frequency signal integrity - and CJ is omitted from all electrical characteristics tables and curves for this specific part number.
