Product details
Overview
BZW04P15HE3/54 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 15.3 V stand-off voltage (VWM), 25.2 V clamping voltage (VC) at 16.0 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - suitable for protecting MOSFETs, sensor interfaces, and microcontroller I/O in automotive and industrial control systems.
For engineers reviewing the BZW04P15HE3/54 datasheet, BZW04P15HE3/54 pinout, BZW04P15HE3/54 application, or BZW04P15HE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, DO-204AL (DO-41) package, bi-directional polarity, low clamping ratio (VC/VWM ≈ 1.65), and 0.088 %/°C breakdown voltage temperature coefficient - critical for stable protection across wide ambient ranges.
Technical Context
This device operates as a bi-directional avalanche diode, leveraging glass-passivated junction technology to achieve fast response (<1 ns) and low incremental surge resistance. Its symmetrical breakdown behavior ensures identical clamping performance in both polarities, eliminating need for polarity-aware layout.
Rated for 175 °C maximum junction temperature and compliant with JESD22-B102 solderability standards, BZW04P15HE3/54 supports high-reliability applications where thermal cycling and lead-free reflow compatibility are mandatory - especially under AEC-Q101 stress test conditions including HTRB, HTGB, and temperature cycling.

Use Scenario: Primary protection for Ethernet PHY or RS-485 transceivers in telecom base station backplanes subjected to AC power cross-talk and lightning surges. IC Role / Device Role / Timing Role: First-stage TVS on twisted-pair lines to shunt common-mode energy before it couples into differential receivers. Use Value: Maintains signal integrity via low capacitance (<100 pF typical) and symmetric clamping - avoids skew or jitter in high-speed data links. |
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 DO-214AA package; higher 600 W PPPM but larger footprint; 24.4 V VC at 23.5 A | Preferred where board space allows SMT and higher surge margin is required (e.g., industrial motor drives) | Select SMBJ15CA only if surface-mount assembly is available and 24.4 V clamping is acceptable for downstream 3.3 V logic |
| P6KE15CA | DO-15 package; same 400 W rating; 24.4 V VC at 16.3 A; non-AEC-Q101, commercial grade only | Suitable for cost-sensitive consumer electronics where automotive qualification is unnecessary | Choose P6KE15CA for non-automotive designs requiring identical electrical specs but lower procurement cost and broader distributor stock |
Compared with BZW04P15HE3/54, SMBJ15CA offers higher surge capacity in a different package but lacks AEC-Q101 validation, while P6KE15CA matches the DO-41 form factor and electrical specs but omits automotive qualification and JESD201 class 2 whisker resistance - making BZW04P15HE3/54 the sole choice for thermally demanding, safety-critical automotive deployments.

FAQ
What does the "HE3/54" suffix mean in BZW04P15HE3/54?
The HE3 suffix indicates RoHS-compliant construction with JESD201 class 2 whisker resistance - required for high-reliability automotive applications - while /54 denotes the preferred packaging: 13-inch paper tape and reel with 550 units per reel. This ensures BZW04P15HE3/54 meets both material compliance and automated assembly requirements without compromising surge performance.
Is BZW04P15HE3/54 unidirectional or bidirectional?
BZW04P15HE3/54 is a bi-directional TVS diode, confirmed by its "B"-free part number designation (BZW04P15 - not BZW04P15B) and explicit listing in the bi-directional column of the Vishay datasheet Table 1. Its symmetrical VBR min/max (17.1 V / 19.8 V) and absence of cathode band marking further verify bidirectional operation - enabling placement across any two-node interface without polarity concern.
How does BZW04P15HE3/54 compare to standard Zener diodes for transient suppression?
Unlike general-purpose Zener diodes, BZW04P15HE3/54 is optimized for transient suppression: it delivers 400 W peak pulse power (vs. typically <1 W for Zeners), sub-1 ns response time, and controlled clamping voltage (25.2 V) under 16.0 A surge - whereas Zeners exhibit higher dynamic impedance and inconsistent avalanche behavior under fast transients. BZW04P15HE3/54 also features glass passivation and AEC-Q101 qualification absent in standard Zeners.
Can BZW04P15HE3/54 be used in place of BZW04P15E3/54?
No - BZW04P15HE3/54 and BZW04P15E3/54 are not interchangeable. The "H" in HE3 signifies AEC-Q101 qualification and JESD201 class 2 whisker resistance, while E3-only parts are commercial grade with class 1A whisker testing. Substituting E3 for HE3 risks failure in automotive applications subject to temperature cycling and long-term reliability validation - BZW04P15HE3/54 must be specified where AEC-Q101 compliance is mandated.
What is the maximum operating temperature for BZW04P15HE3/54?
The maximum operating junction temperature for BZW04P15HE3/54 is +175 °C, as specified in the Vishay datasheet Absolute Maximum Ratings table. This enables reliable operation in under-hood automotive environments and high-temperature industrial enclosures - provided PCB thermal design maintains junction-to-ambient thermal resistance below the derating curve limits shown in Figure 5 of document 88316.
