Product details
Overview
BZW04P15BHE3/73 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 15.3 V stand-off voltage (VWM), 25.2 V maximum clamping voltage (VC) at 16.0 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 BZW04P15BHE3/73 datasheet, BZW04P15BHE3/73 pinout, BZW04P15BHE3/73 application, or BZW04P15BHE3/73 equivalent, key selection criteria include its bi-directional clamping behavior, low 1.0 µA reverse leakage at VWM, 175 °C max junction temperature, and compatibility with 8.3 ms surge waveforms in industrial sensor protection and automotive control modules.
Technical Context
This bi-directional TVS operates symmetrically in both polarities, with breakdown voltage (VBR) specified between 17.1 V and 19.8 V at 1.0 mA test current. Its glass-passivated junction ensures stable performance under repetitive surge stress, while the low incremental surge resistance enables effective voltage limiting during fast transients.
The device complies with ANSI/IEEE C62.35 surge standards and supports 0.01% duty cycle repetitive operation. Its thermal design accommodates lead temperature up to 75 °C for 1.5 W continuous power dissipation, and it meets JESD201 class 2 whisker resistance requirements due to matte tin plating.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15CA | Same VWM (15.3 V), higher IPPM (23.5 A), SMC package (surface-mount) | Requires PCB rework for SMT layout; better thermal dissipation in high-density designs | Select when board space is constrained and automated assembly is preferred over through-hole. |
| P6KE15CA | Same VWM (15.3 V), lower PPPM (600 W), DO-15 package (larger than DO-41) | Higher surge margin but larger footprint; less suitable for compact automotive modules | Choose for legacy designs where DO-15 is standardized and higher peak power is required. |

FAQ
What is the clamping voltage of BZW04P15BHE3/73 under a 10/1000 µs surge?
The BZW04P15BHE3/73 exhibits a maximum clamping voltage (VC) of 25.2 V when subjected to its rated 16.0 A peak pulse current (IPPM) using the standard 10/1000 µs waveform. This value is measured at TA = 25 °C and defines the upper voltage limit imposed on the protected circuit during transient events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is BZW04P15BHE3/73 suitable for automotive applications?
Yes, BZW04P15BHE3/73 is AEC-Q101 qualified and explicitly rated for automotive use. Its construction - including glass-passivated junction, matte tin-plated leads meeting JESD201 class 2 whisker resistance, and 175 °C maximum junction temperature - satisfies stress testing requirements for engine control units, body electronics, and sensor modules. The HE3 suffix denotes AEC-Q101 qualification per Vishay's ordering nomenclature.
How does the bi-directional nature of BZW04P15BHE3/73 affect its circuit placement?
The bi-directional configuration of BZW04P15BHE3/73 means it functions identically in both polarities, with no cathode marking and symmetrical VBR/VC characteristics. This allows direct placement across AC-coupled lines, differential pairs (e.g., RS-485), or ungrounded signal paths without orientation concerns - simplifying layout and eliminating risk of reverse installation errors in high-volume manufacturing.
What is the maximum continuous power dissipation for BZW04P15BHE3/73?
The BZW04P15BHE3/73 has a maximum continuous power dissipation (PD) of 1.5 W when mounted on an infinite heatsink at lead temperature (TL) = 75 °C. This rating applies to steady-state DC or low-frequency conditions and is derated linearly above 25 °C ambient per the published power derating curve (Fig. 5 in datasheet 88316). It is not intended for sustained surge handling - only for leakage-related heating under normal operation.
Does BZW04P15BHE3/73 meet RoHS and REACH requirements?
Yes, BZW04P15BHE3/73 is RoHS-compliant per Directive 2011/65/EU and conforms to WEEE 2002/96/EC. The HE3 suffix confirms compliance, and the molding compound meets UL 94 V-0 flammability standards. Vishay certifies that all RoHS-compliant products fulfill material restrictions for lead, mercury, cadmium, hexavalent chromium, PBB, and PBDE - with full substance declarations available upon request.
