Product details
Overview
BZW04P15-E3/73 from Vishay General Semiconductor is a bi-directional TransZorb® transient voltage suppressor (TVS) diode in DO-204AL (DO-41) package, designed for clamping fast-rising ESD and surge transients on signal/power lines. It features 15.3 V standoff voltage (VWM), 25.2 V maximum clamping voltage (VC) at 16.0 A peak pulse current (IPPM), and 400 W peak pulse power (10/1000 μs waveform), making it suitable for protecting MOSFET gates, sensor interfaces, and industrial I/O lines.
For engineers reviewing the BZW04P15-E3/73 datasheet, BZW04P15-E3/73 pinout, BZW04P15-E3/73 application, or BZW04P15-E3/73 equivalent, key selection criteria include its bi-directional clamping capability, AEC-Q101 qualification, low leakage (<1.0 μA at VWM), 175 °C max junction temperature, and RoHS-compliant matte tin-plated leads - all critical for automotive and harsh-environment designs.
Technical Context
This device operates as a voltage-clamping protector with symmetrical breakdown behavior in both polarities, enabling robust protection of AC-coupled or bidirectional signal paths without polarity concerns. Its glass-passivated junction ensures stable avalanche characteristics and low incremental surge resistance, while the 10/1000 μs surge rating reflects standardized lightning/surge immunity testing per ANSI/IEEE C62.35.
The BZW04P15-E3/73 is rated for 400 W non-repetitive peak pulse power and exhibits a temperature coefficient of breakdown voltage of +0.088 %/°C - a key parameter for thermal stability in wide-temperature-range applications. Its 1.5 W steady-state power dissipation and 175 °C maximum junction temperature support reliable operation in high-ambient industrial environments.

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 bi-directional DO-214AA package; 15 V VWM, 24.4 V VC @ 16.3 A; lower 600 W PPPM rating but higher IPPM. | Higher surge current capacity suits higher-energy lightning surges; larger SMB package requires PCB area increase. | Select when needing higher peak current headroom and board space allows SMB footprint. |
| P6KE15CA | DO-15 package; 15 V VWM, 24.4 V VC @ 16.3 A; 600 W PPPM; same AEC-Q101 qualification not confirmed. | Legacy through-hole alternative; lacks E3 whisker test certification and explicit AEC-Q101 documentation. | Choose only for legacy through-hole designs where DO-41 axial lead compatibility is mandatory. |
Compared with SMBJ15CA and P6KE15CA, the BZW04P15-E3/73 offers verified AEC-Q101 qualification, JESD201 Class 1A whisker resistance, and DO-41 form factor ideal for space-constrained automotive modules - while maintaining identical 15 V standoff and sub-26 V clamping performance.

FAQ
What is the clamping voltage of the BZW04P15-E3/73 under maximum surge conditions?
The BZW04P15-E3/73 has a maximum clamping voltage (VC) of 25.2 V when subjected to its rated 16.0 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured at TA = 25 °C and defines the upper voltage limit imposed on protected circuitry during transient events. The BZW04P15-E3/73 maintains this clamping performance across its full operating temperature range due to its specified +0.088 %/°C VBR temperature coefficient.
Is the BZW04P15-E3/73 suitable for automotive applications?
Yes, the BZW04P15-E3/73 is explicitly AEC-Q101 qualified, as confirmed in Vishay's datasheet revision 12-Jul-11 (Document Number: 88316). It meets stress-test requirements including high-temperature reverse bias (HTRB), temperature cycling, and mechanical shock - making it suitable for engine control units, body electronics, and ADAS sensor interfaces. The BZW04P15-E3/73 also carries the E3 suffix, indicating compliance with JESD201 Class 1A whisker testing for automotive reliability.
How does the bi-directional nature of the BZW04P15-E3/73 affect its placement in circuit design?
The bi-directional architecture of the BZW04P15-E3/73 eliminates polarity sensitivity, allowing it to be placed across any two nodes without regard to anode/cathode orientation - ideal for AC signal lines, differential buses (e.g., CAN, RS-485), or ungrounded power rails. Unlike uni-directional TVS diodes, the BZW04P15-E3/73 provides symmetrical clamping for both positive and negative transients, simplifying layout and reducing BOM complexity. No color band marking is present on the BZW04P15-E3/73 package.
What is the maximum steady-state power dissipation rating for the BZW04P15-E3/73?
The BZW04P15-E3/73 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 and Thermal Characteristics" table. This rating assumes ideal thermal conduction and must be derated linearly above 25 °C ambient per the published derating curve (Fig. 5). The BZW04P15-E3/73 is not intended for continuous power dissipation but rather for transient energy absorption; its 1.5 W PD supports safe operation during brief fault conditions.
Does the BZW04P15-E3/73 have RoHS and REACH compliance documentation?
Yes, the BZW04P15-E3/73 carries the E3 suffix, which Vishay specifies as RoHS-compliant per Directive 2011/65/EU and compliant with WEEE 2002/96/EC. The device's molding compound meets UL 94 V-0 flammability rating, and its matte tin-plated leads satisfy J-STD-002 solderability and JESD22-B102 wetting balance requirements. Full compliance documentation, including material declarations and substance reports, is available via Vishay's official product page and Aetrix Electronics' quality portal for the BZW04P15-E3/73.
