Product details
Overview
BZW04P13HE3/73 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 12.8 V stand-off voltage (VWM), 21.2 V clamping voltage (VC) at 19.0 A peak pulse current, 400 W peak pulse power (10/1000 µs), and AEC-Q101 qualification - making it suitable for automotive sensor interface protection and industrial I/O line surge suppression.
For engineers reviewing the BZW04P13HE3/73 datasheet, BZW04P13HE3/73 pinout, BZW04P13HE3/73 application, or BZW04P13HE3/73 equivalent, key selection criteria include its bi-directional clamping behavior, DO-204AL (DO-41) through-hole package, low 0.084 %/°C VBR temperature coefficient, and compliance with automotive reliability standards.
Technical Context
This device operates as a voltage-clamped shunt protector: during transients exceeding VWM, it avalanches to limit voltage across protected circuitry. Its glass-passivated junction ensures stable breakdown and low incremental surge resistance, enabling fast response (<1 ns) to ESD and lightning-induced surges.
The bi-directional configuration supports symmetric clamping in AC-coupled or floating signal paths, with identical electrical characteristics in both polarities. It is rated for repetitive 10/1000 µs pulses at 0.01 % duty cycle and derates linearly above 25 °C ambient per the published thermal curve.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 12.8 V - Maximum continuous reverse operating voltage before conduction begins; defines safe operating margin below clamping threshold. |
| VC @ IPPM | 21.2 V at 19.0 A - Clamped voltage during 10/1000 µs surge; determines maximum stress on downstream ICs like microcontrollers or transceivers. |
| PPPM | 400 W - Peak pulse power handling capability; validates suitability for IEC 61000-4-5 Level 3 (1 kV/2 Ω) surge events. |
| VBR min/max | 14.3 V / 16.5 V at 1.0 mA - Breakdown voltage range defining turn-on consistency; critical for predictable protection timing. |
| TJ max | +175 °C - Maximum junction temperature; enables operation in under-hood automotive environments and high-power industrial enclosures. |
| Temp. Coeff. | +0.084 %/°C - Low VBR drift with temperature; maintains clamping accuracy across wide ambient ranges without recalibration. |
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 per datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |

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 | Same VWM (13.0 V), higher VC (21.5 V), SMC package (surface-mount), 600 W PPPM. | Requires PCB redesign for SMD layout; better suited for high-density consumer electronics vs. through-hole industrial designs. | Select SMBJ13CA when board space is constrained and automated assembly is preferred; verify thermal pad design for 600 W dissipation. |
| 1.5KE13CA | Same VWM (13.0 V), identical DO-204AL package, but lower PPPM (1500 W), higher VC (23.0 V), no AEC-Q101 qualification. | Lacks automotive qualification and has looser clamping; acceptable for commercial-grade industrial use only. | Choose 1.5KE13CA for cost-sensitive non-automotive applications where 23.0 V clamping is tolerable and AEC-Q101 is not required. |
Compared with BZW04P13HE3/73, SMBJ13CA offers higher surge rating in a smaller footprint but demands layout changes, while 1.5KE13CA retains the same through-hole form factor but sacrifices automotive qualification and clamping precision - making BZW04P13HE3/73 the optimal choice for AEC-Q101–mandated designs requiring tight VC control.

FAQ
What is the clamping voltage of BZW04P13HE3/73 at its rated peak pulse current?
The BZW04P13HE3/73 has a maximum clamping voltage (VC) of 21.2 V at 19.0 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per Figure 1 and Table 1 of Vishay Document 88316 and defines the upper voltage limit imposed on protected circuitry during surge events. The BZW04P13HE3/73 maintains this clamping performance across its full operating temperature range.
Is BZW04P13HE3/73 suitable for automotive applications?
Yes, BZW04P13HE3/73 is AEC-Q101 qualified (confirmed by the HE3 suffix per Vishay's ordering information and Mechanical Data section), making it suitable for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. Its operating junction temperature range of -55 °C to +175 °C and robust surge handling align with automotive environmental requirements. The BZW04P13HE3/73 meets these specifications without derating in typical under-hood conditions.
What does the "HE3" suffix indicate in BZW04P13HE3/73?
The "HE3" suffix in BZW04P13HE3/73 denotes RoHS-compliant construction with AEC-Q101 qualification and JESD201 Class 2 whisker resistance. Per Vishay's Mechanical Data section, "HE3" indicates the part meets automotive reliability standards and uses matte tin-plated leads qualified for high-reliability soldering. This distinguishes BZW04P13HE3/73 from commercial-grade "E3" variants and confirms its suitability for mission-critical automotive deployments.
How does BZW04P13HE3/73 differ from uni-directional versions like BZW04P13E3/73?
BZW04P13HE3/73 is a bi-directional TVS diode with symmetrical clamping in both polarities, whereas uni-directional variants (e.g., BZW04P13E3/73) conduct only in reverse bias and require correct polarity orientation. The bi-directional nature of BZW04P13HE3/73 eliminates marking and orientation concerns in AC-coupled or floating circuits, and its electrical characteristics - including VWM, VC, and IPPM - apply identically in either direction per the datasheet's "bi-directional types" note.
What is the maximum steady-state power dissipation for BZW04P13HE3/73?
The BZW04P13HE3/73 has a maximum steady-state power dissipation (PD) of 1.5 W when mounted on an infinite heatsink at lead temperature (TL) = 75 °C, as specified in the Maximum Ratings table. This value decreases linearly above 25 °C ambient per the derating curve in Figure 5. Unlike transient ratings, this PD limit applies only to continuous DC or low-frequency reverse leakage - the BZW04P13HE3/73 is not intended for sustained power dissipation.
