Product details
Overview
BZW04P13B-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 12.8 V stand-off voltage (VWM), 14.3–16.5 V breakdown voltage (VBR) at 1 mA, 21.2 V clamping voltage (VC) at 19.0 A peak pulse current, and 400 W peak pulse power capability with a 10/1000 µs waveform - deployed in automotive sensor interfaces, industrial I/O protection, and telecom line surge suppression.
For engineers reviewing the BZW04P13B-E3/54 datasheet, BZW04P13B-E3/54 pinout, BZW04P13B-E3/54 application, or BZW04P13B-E3/54 equivalent, key selection criteria include its DO-204AL (DO-41) axial package, bi-directional polarity, AEC-Q101 qualification, 175 °C maximum junction temperature, and compliance with IEC 61000-4-2/4-4/4-5 surge immunity standards.
Technical Context
This bi-directional TVS diode operates symmetrically in both forward and reverse bias, enabling clamping of positive and negative transients without polarity constraints. Its glass-passivated junction ensures stable leakage performance (<1 µA at VWM) and low incremental surge resistance, critical for fast response to ESD and lightning-induced surges.
The device sustains repetitive 10/1000 µs pulses at 0.01% duty cycle and derates linearly above 25 °C ambient per Vishay's Fig. 2 curve. With a temperature coefficient of VBR at +0.084 %/°C, it maintains predictable clamping behavior across automotive-grade temperature ranges (–55 °C to +175 °C).
Key Specifications

IC Role / Device Role / Timing Role: Primary overvoltage suppression element on 24 V DC I/O lines, coordinated with series impedance and filtering. Use Value: Absorbs 400 W surge energy without degradation, maintaining signal integrity during factory automation equipment switching events. |
| Telecom Line Interface | Consumer Appliance Power Supply |
Use Scenario: Safeguarding Ethernet PHYs, RS-485 transceivers, and DSL line drivers from lightning-induced surges on outdoor-facing ports. IC Role / Device Role / Timing Role: First-stage transient suppressor in multi-stage protection network, preceding GDT or polymer PTC. Use Value: Responds in <1 ns to sub-microsecond ESD events (IEC 61000-4-2 ±8 kV contact), limiting voltage overshoot to safe levels. |
Use Scenario: Protecting AC-DC adapter primary-side rectifiers and secondary-side 12 V/5 V rails from mains-borne surges and capacitor discharge spikes. IC Role / Device Role / Timing Role: Secondary-level clamping device across DC output rails, complementing MOV-based primary protection. Use Value: Provides precise 12.8 V standoff with low leakage, avoiding false triggering while ensuring fast response to fast-rising transients. |
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 | DO-214AA (SMB) package; 13 V VWM, 21.5 V VC at 17.9 A; same 400 W PPPM rating. | Surface-mount footprint; requires PCB redesign; better thermal dissipation in high-density layouts. | Select when board space is constrained and reflow assembly is preferred over through-hole. |
| P6KE13CA | DO-15 package; 13 V VWM, 23.2 V VC at 17.2 A; lower 600 W peak power but slower response due to higher junction capacitance. | Legacy through-hole alternative; higher clamping voltage increases risk to sensitive 3.3 V logic. | Acceptable for cost-sensitive industrial controls where 23.2 V clamping is within system margin. |
Compared with BZW04P13B-E3/54, SMBJ13CA offers superior mountability and thermal performance in SMT designs, while P6KE13CA trades clamping precision and speed for broader legacy availability - neither is pin-compatible, but all three meet IEC 61000-4-5 Level 3 requirements.

FAQ
What is the maximum clamping voltage of BZW04P13B-E3/54 under surge conditions?
The BZW04P13B-E3/54 has a maximum clamping voltage (VC) of 21.2 V at 19.0 A peak pulse current (IPPM) with a 10/1000 µs waveform. This value is measured per IEC 61000-4-5 test conditions and represents the highest voltage imposed on the protected circuit during a standardized surge event. The BZW04P13B-E3/54 maintains this clamping performance across its full operating temperature range (–55 °C to +175 °C).
Is BZW04P13B-E3/54 suitable for automotive applications?
Yes, BZW04P13B-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use, including engine control units, body electronics, and ADAS sensor interfaces. Its DO-204AL package withstands mechanical vibration, its 175 °C TJmax supports under-hood placement, and its bi-directional clamping protects against both load-dump and reverse-battery transients. The BZW04P13B-E3/54 meets all stress tests defined in AEC-Q101 Rev D, including HTSL, TC, and HTRB.
How does the bi-directional design of BZW04P13B-E3/54 affect circuit layout?
The bi-directional design of BZW04P13B-E3/54 eliminates polarity marking - both leads are functionally identical, allowing unrestricted orientation during manual or automated insertion. This simplifies PCB layout (no silkscreen polarity indicators needed), reduces assembly errors, and enables reuse in either direction across differential or single-ended lines. The BZW04P13B-E3/54 achieves symmetrical clamping in both directions, making it ideal for AC-coupled or floating signal paths like RS-485 or CAN bus stubs.
What is the leakage current specification for BZW04P13B-E3/54 at its stand-off voltage?
At its 12.8 V stand-off voltage (VWM) and 25 °C ambient, the BZW04P13B-E3/54 exhibits a maximum reverse leakage current (ID) of 1.0 µA. This low leakage ensures minimal power loss and avoids false triggering in high-impedance sensing circuits. The BZW04P13B-E3/54 maintains leakage below 5 µA up to 150 °C, supporting stable operation in thermally demanding applications without compromising signal fidelity.
Can BZW04P13B-E3/54 replace uni-directional TVS diodes in existing designs?
BZW04P13B-E3/54 can replace uni-directional TVS diodes only if the circuit topology is inherently symmetrical or referenced to ground on both sides - such as differential data lines or AC-powered inputs. It must not be used in DC-biased unidirectional paths (e.g., 12 V supply rail to ground) without verifying that reverse conduction does not disrupt bias networks. The BZW04P13B-E3/54 provides identical clamping in both directions, so design validation is required before drop-in substitution.
