Product details
Overview
BZW04P13-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), 21.2 V clamping voltage (VC) at 19.0 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive sensor interfaces, industrial I/O modules, and telecom line protection.
For engineers reviewing the BZW04P13-E3/54 datasheet, BZW04P13-E3/54 pinout, BZW04P13-E3/54 application, or BZW04P13-E3/54 equivalent, key selection criteria include its DO-204AL (DO-41) package, AEC-Q101 qualification, bi-directional symmetry, low clamping ratio (VC/VWM ≈ 1.66), and 0.084 %/°C temperature coefficient of VBR - critical for stable surge response across automotive temperature ranges.
Technical Context
This bi-directional TVS operates symmetrically in both polarities, with identical electrical characteristics forward and reverse - enabling single-device protection of AC-coupled or differential signal paths without polarity concerns. Its glass-passivated junction ensures stable leakage performance and fast response (<1 ns), while the 10/1000 μs waveform rating reflects standardized surge immunity testing per ANSI/IEEE C62.35.
The device is rated for 175 °C maximum junction temperature and derates linearly above 25 °C ambient, supporting operation in under-hood automotive environments. Its 1.5 W steady-state power dissipation (PD) and 1.0 mA test current (IT) align with IEC 61000-4-5 surge compliance requirements for Level 3–4 system-level transient immunity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 12.8 V - maximum continuous working voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR min/max | 14.3 V / 16.5 V at 1.0 mA - tight breakdown window ensures predictable turn-on during transients. |
| VC @ IPPM | 21.2 V at 19.0 A - clamping voltage limits downstream IC stress during 400 W surges. |
| PPPM | 400 W (10/1000 μs) - industry-standard surge energy handling for automotive and industrial applications. |
| ID @ VWM | 1.0 μA - ultra-low reverse leakage preserves signal integrity in high-impedance sensor circuits. |
| TJ max | 175 °C - supports AEC-Q101 qualification and under-hood deployment without thermal derating penalties. |
| Temp. coeff. | 0.084 %/°C - low VBR drift ensures consistent clamping threshold across -55 °C to +175 °C range. |
Pinout & Package
Package: DO-204AL (DO-41), axial-leaded, epoxy-molded case meeting UL 94 V-0 flammability rating; matte tin-plated leads compliant with J-STD-002 and JESD22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (bi-directional) | Non-polarized terminals | No marking; symmetrical conduction enables placement without orientation check - simplifies automated assembly and reduces BOM variants. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable leakage current and long-term reliability under thermal cycling and humidity exposure. |
| AEC-Q101 qualified | Validated for automotive-grade stress tests including HTOL, TC, UHAST, and ESD - suitable for engine control and ADAS subsystems. |
| 400 W peak pulse power (10/1000 μs) | Meets IEC 61000-4-5 surge immunity requirements for industrial and telecom infrastructure equipment. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ISO 7637-2 pulse 1/2a/5a), improving protection margin. |
| RoHS-compliant, E3 suffix | Meets JESD201 Class 1A whisker resistance - eliminates tin whisker risk in high-reliability PCB assemblies. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |

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 | Same DO-214AA package; higher 600 W PPPM but larger 23.2 V VC at 24.7 A - less precise clamping than BZW04P13-E3/54's 21.2 V. | Preferred where board space allows SMB footprint and higher surge margin is prioritized over clamping tightness. | Select SMBJ13CA when surge energy exceeds 400 W or when using surface-mount assembly processes. |
| P6KE13CA | DO-15 package; same 12.4–13.7 V VBR range but lower 5.0 W PD and 600 W PPPM - larger thermal mass but less suited for high-density layouts. | Used in legacy designs with through-hole assembly and less stringent thermal constraints. | Choose P6KE13CA only if DO-15 footprint compatibility is required and AEC-Q101 qualification is not mandatory. |
Compared with SMBJ13CA and P6KE13CA, BZW04P13-E3/54 offers tighter clamping (21.2 V), AEC-Q101 qualification, and DO-41 packaging optimized for axial leaded high-reliability applications - making it the preferred choice for new automotive and industrial designs requiring validated automotive-grade surge immunity.

FAQ
What is the clamping voltage of BZW04P13-E3/54 and why does it matter?
The BZW04P13-E3/54 has a maximum clamping voltage (VC) of 21.2 V at 19.0 A peak pulse current (10/1000 μs). This value defines the highest voltage imposed on protected circuitry during a surge event. A lower VC relative to the protected IC's absolute maximum rating - such as 21.2 V vs. a 24 V rail or 30 V interface - ensures safe operation without damage or functional interruption. The BZW04P13-E3/54 achieves this with minimal overshoot due to its low incremental surge resistance.
Is BZW04P13-E3/54 suitable for automotive applications?
Yes, BZW04P13-E3/54 is AEC-Q101 qualified and rated for operation from -55 °C to +175 °C junction temperature - meeting core requirements for under-hood and cabin electronics. Its bi-directional symmetry, low leakage (<1.0 μA), and stable VBR temperature coefficient (0.084 %/°C) make it appropriate for protecting CAN transceivers, LIN buses, and sensor signal conditioning circuits in modern vehicles. The E3 suffix also confirms JESD201 Class 1A whisker resistance for long-term reliability.
How does the bi-directional nature of BZW04P13-E3/54 affect circuit design?
The bi-directional configuration of BZW04P13-E3/54 means it behaves identically in both polarities - no cathode marking, no orientation dependency during placement. This simplifies layout, eliminates polarity verification in automated assembly, and enables use in AC-coupled or differential signal paths (e.g., RS-485, CAN, audio lines) where voltage reversals occur. Unlike uni-directional TVS diodes, BZW04P13-E3/54 provides symmetrical clamping without requiring back-to-back diode configurations.
What is the difference between BZW04P13-E3/54 and BZW04P13B?
BZW04P13-E3/54 specifies RoHS-compliant commercial-grade packaging (E3 suffix) in 13" paper tape and reel (54 = package code), while BZW04P13B denotes the bi-directional variant without packaging or qualification details. The "B" suffix alone indicates bi-directionality; "E3/54" adds RoHS compliance, JESD201 Class 1A whisker resistance, and standard reel delivery. Both share identical electrical specs (VWM = 12.8 V, VC = 21.2 V), but only BZW04P13-E3/54 guarantees traceable, automotive-suitable supply chain documentation.
Can BZW04P13-E3/54 be used in parallel for higher surge current handling?
No - BZW04P13-E3/54 is not recommended for parallel connection due to parameter mismatch (e.g., VBR tolerance of ±5 %) causing current imbalance and premature failure of one device. For higher IPPM requirements, select a single higher-rated TVS (e.g., BZW04P15-E3/54 or SMBJ15CA) or implement staged protection with GDT + TVS coordination. Parallel use would require matched-bin devices and external balancing resistors - not supported by Vishay's design guidance for this part.
