Product details
Overview
BZW04-10B-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on signal or power lines. It features 10.2 V stand-off voltage (VWM), 11.4–12.6 V breakdown voltage (VBR) at 1 mA, 16.7 V maximum clamping voltage (VC) at 24 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - suitable for protecting I/O interfaces in industrial sensor modules.
For engineers reviewing the BZW04-10B-E3/54 datasheet, BZW04-10B-E3/54 pinout, BZW04-10B-E3/54 application, or BZW04-10B-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-41 through-hole compatibility, AEC-Q101 qualification status, junction temperature range (−55 °C to +175 °C), and low leakage (<1.0 μA at VWM).
Technical Context
This device operates as a voltage-clamped surge protector using an avalanche breakdown mechanism in both directions. Its glass-passivated junction ensures stable VBR tolerance and low incremental surge resistance, enabling consistent clamping performance under repetitive 10/1000 μs transients at 0.01% duty cycle.
The BZW04-10B-E3/54 exhibits a temperature coefficient of VBR at +0.078 %/°C and maintains ≤1.0 μA reverse leakage at 10.2 V, supporting reliable operation across automotive and industrial ambient conditions. It is rated for 1.5 W steady-state power dissipation on infinite heatsink at TL = 75 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10.2 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR min/max | 11.4 V / 12.6 V at 1 mA - defines guaranteed avalanche onset window for design margining |
| VC @ IPPM | 16.7 V at 24 A - clamping voltage during 10/1000 μs surge, limiting downstream stress |
| PPPM | 400 W - peak transient energy absorption capacity per single event |
| ID @ VWM | <1.0 μA - ultra-low leakage preserves signal integrity in high-impedance circuits |
| TJ max | +175 °C - enables use in under-hood or enclosed industrial environments |
| Package | DO-41 (DO-204AL) - standard axial-leaded through-hole package with UL 94 V-0 molding |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA | DO-214AA package, 10 V VWM, 17.0 V VC @ 23.3 A, same 400 W PPPM | Surface-mount alternative requiring PCB redesign; higher thermal resistance than DO-41 | Select when space-constrained layouts preclude axial-leaded components |
| P6KE10CA | DO-15 package, 10 V VWM, 17.0 V VC @ 23.3 A, 600 W PPPM (10/1000 μs) | Higher peak power rating but larger footprint and lower surge current density | Choose for legacy designs already using DO-15 footprints or where 600 W headroom is required |
Compared with SMBJ10CA and P6KE10CA, the BZW04-10B-E3/54 offers identical VWM and clamping performance in a smaller DO-41 outline, with AEC-Q101 qualification and lower thermal resistance than DO-15 - making it optimal for new automotive and industrial through-hole designs prioritizing reliability and board-level surge robustness.

FAQ
What is the polarity configuration of BZW04-10B-E3/54?
The BZW04-10B-E3/54 is a bidirectional TVS diode with symmetrical avalanche characteristics in both directions. Unlike unidirectional variants, it carries no cathode band marking - either lead may serve as input or return path, simplifying layout for AC-coupled or differential signal lines.
Is BZW04-10B-E3/54 qualified for automotive applications?
Yes, BZW04-10B-E3/54 is AEC-Q101 qualified, confirming its suitability for automotive electronics including engine control units, body control modules, and ADAS sensor interfaces. The qualification covers temperature cycling, humidity testing, and surge endurance per automotive reliability standards.
What is the maximum clamping voltage of BZW04-10B-E3/54 under surge conditions?
The BZW04-10B-E3/54 has a maximum clamping voltage (VC) of 16.7 V at 24 A peak pulse current with a 10/1000 μs waveform. This value is guaranteed across temperature and ensures protected downstream ICs remain within safe operating voltage limits during transient events.
How does the DO-41 package of BZW04-10B-E3/54 compare thermally to surface-mount alternatives?
The DO-41 package of BZW04-10B-E3/54 provides lower thermal resistance than comparable SMD packages like SMB (DO-214AA), enabling more efficient heat dissipation in high-reliability through-hole designs. Its axial leads facilitate direct mounting to heatsinks or chassis ground planes for enhanced surge handling.
Can BZW04-10B-E3/54 be used in AC line protection applications?
No - BZW04-10B-E3/54 is rated for 10.2 V stand-off voltage and is not intended for AC mains (120/230 VAC) protection. It is designed for low-voltage DC signal and power rail protection (e.g., 12 V, 24 V systems). For AC line applications, higher-voltage TVS families such as the 1.5KE or SA series are appropriate.
