Product details
Overview
BZW04P15B-E3/54 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 capability with a 10/1000 µs waveform - ideal for safeguarding MOSFETs and sensor interfaces against inductive switching transients.
For engineers reviewing the BZW04P15B-E3/54 datasheet, BZW04P15B-E3/54 pinout, BZW04P15B-E3/54 application, or BZW04P15B-E3/54 equivalent, key selection criteria include its DO-41 package compatibility, bi-directional surge handling, AEC-Q101 qualification, low leakage (<1 µA at VWM), and precise 17.1–19.8 V breakdown range - critical for automotive and industrial ESD/surge co-design.
Technical Context
This bi-directional TVS diode uses a glass passivated chip junction to achieve fast response time (<1 ns), low incremental surge resistance, and stable clamping under repetitive 10/1000 µs transients at 0.01% duty cycle. Its symmetrical I-V characteristics ensure identical protection in both polarities without polarity marking.
Rated for operation from –55 °C to +175 °C junction temperature, it supports high-reliability applications with 1.5 W steady-state power dissipation on infinite heatsink and compliance to JESD22-B106 soldering (275 °C, 10 s). The device meets RoHS Directive 2011/65/EU and is AEC-Q101 qualified per note (1) in the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 15.3 V - maximum continuous reverse working voltage before significant leakage; defines safe operating margin below clamping threshold |
| VBR (min/max) | 17.1 V / 19.8 V at 1.0 mA - guaranteed breakdown onset range; ensures consistent turn-on across production lots |
| VC @ IPPM | 25.2 V at 16.0 A - clamped voltage during 10/1000 µs surge; limits downstream IC stress to safe levels |

IC Role / Device Role / Timing Role: Fast-clamping element parallel to load, triggered within nanoseconds to limit overshoot during hot-plug or short-circuit recovery. Use Value: Clamps 16 A surges to 25.2 V while maintaining <1 µA leakage at 15.3 V - preserving efficiency and no-load regulation. |
Use Scenario: Protecting Ethernet PHYs and DSL line drivers from lightning-induced surges coupled onto twisted-pair telecom lines. IC Role / Device Role / Timing Role: First-stage protector in hybrid protection circuit (with GDT and PTC), absorbing initial energy before secondary clamping.

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) and VC (24.4 V), but SMC package (higher thermal mass); 600 W PPPM | Preferred where board space allows larger footprint and higher surge margin is required | Select SMBJ15CA for enhanced thermal endurance in high-duty-cycle surge environments |
| 1.5KE15CA | Higher PPPM (1500 W), same DO-41 package; VC = 24.4 V, but higher leakage (5 µA) | Used in legacy industrial designs requiring higher single-pulse energy absorption | Choose 1.5KE15CA only when 1500 W rating is mandatory and leakage tolerance permits |
Compared with BZW04P15B-E3/54, SMBJ15CA offers superior thermal performance in SMC form factor but requires PCB redesign, while 1.5KE15CA delivers triple the pulse power in the same DO-41 outline at the cost of higher leakage and reduced precision - making BZW04P15B-E3/54 optimal for AEC-Q101-compliant, low-leakage, mid-power surge protection.

FAQ
What is the exact breakdown voltage range for BZW04P15B-E3/54?
The BZW04P15B-E3/54 has a guaranteed breakdown voltage (VBR) range of 17.1 V to 19.8 V measured at 1.0 mA test current, per the Vishay datasheet revision 12-Jul-11, page 2. This tight tolerance ensures predictable turn-on behavior across temperature and production lots, critical for repeatable system-level surge immunity.
Is BZW04P15B-E3/54 suitable for automotive applications?
Yes, BZW04P15B-E3/54 is AEC-Q101 qualified (as noted in datasheet footnote (1)), operates from –55 °C to +175 °C, and is manufactured with whisker-tested E3 terminations. These attributes make BZW04P15B-E3/54 appropriate for under-hood and body electronics where reliability under thermal cycling and vibration is mandatory.
Does BZW04P15B-E3/54 have polarity markings?
No, BZW04P15B-E3/54 is a bi-directional TVS diode and carries no polarity marking - its terminals are functionally identical. The device provides symmetrical clamping in both directions, eliminating orientation errors during manual or automated assembly.
What is the clamping voltage of BZW04P15B-E3/54 at rated surge current?
At its rated peak pulse current of 16.0 A (10/1000 µs waveform), BZW04P15B-E3/54 clamps to a maximum of 25.2 V. This value is specified in the Electrical Characteristics table (page 2) and defines the upper voltage limit imposed on protected circuitry during standardized surge events.
Can BZW04P15B-E3/54 replace uni-directional TVS diodes in existing designs?
BZW04P15B-E3/54 can replace uni-directional variants only if the circuit is inherently symmetrical (e.g., AC-coupled lines, differential buses) and does not rely on forward conduction for normal operation. Its bi-directional nature eliminates cathode/anode constraints but does not provide DC forward path functionality - verify system-level polarity requirements before substitution.
