Product details
Overview
BZW04P10-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 10.2 V stand-off voltage (VWM), 16.7 V maximum clamping voltage (VC) at 24.0 A peak pulse current (IPPM), and 400 W peak pulse power (PPPM) capability with 10/1000 µs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the BZW04P10-E3/54 datasheet, BZW04P10-E3/54 pinout, BZW04P10-E3/54 application, or BZW04P10-E3/54 equivalent, key selection criteria include its DO-204AL (DO-41) package, AEC-Q101 qualification, bi-directional symmetry, low 0.078 %/°C VBR temperature coefficient, and compliance with IEC 61000-4-2/4-4/4-5 surge immunity requirements.
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 floating signal paths without polarity concerns. Its glass-passivated junction ensures stable breakdown behavior and low incremental surge resistance under repetitive transients.
The device delivers fast response time (<1 ns) and excellent clamping performance, maintaining VC ≤ 16.7 V at IPPM = 24.0 A (10/1000 µs), while supporting continuous power dissipation of 1.5 W on an infinite heatsink and operating across –55 °C to +175 °C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10.2 V - maximum continuous working voltage before conduction; defines safe operating margin below clamping threshold |
| VBR min/max | 11.4 V / 13.2 V at IT = 1.0 mA - precise breakdown onset ensures predictable turn-on during ESD or surge events |
| VC @ IPPM | 16.7 V at 24.0 A (10/1000 µs) - limits downstream voltage stress to protect 12 V-rated ICs and MOSFETs |
| PPPM | 400 W - sustains high-energy transients such as ISO 7637-2 Pulse 1/2a/3a and IEC 61000-4-5 combination wave surges |
| ID @ VWM | 1.0 µA - ultra-low leakage preserves signal integrity and battery life in always-on sensor circuits |
| TJ max | +175 °C - supports under-hood automotive placement and high-ambient industrial environments |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
Pinout & Package
Package: DO-204AL (DO-41), axial-leaded, molded epoxy case meeting UL 94 V-0; matte tin-plated leads compliant with J-STD-002 and JESD22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Current entry terminal in forward bias | Not functional as rectifier; used only for mechanical orientation - bi-directional operation renders polarity irrelevant |
| Cathode (unmarked end) | Current exit terminal in forward bias | No color band or marking; terminals are electrically symmetric - either lead serves as line or return path |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated chip junction | Ensures stable, repeatable breakdown voltage with minimal parameter drift over temperature and lifetime |
| 400 W peak pulse power (10/1000 µs) | Withstands automotive load dump and lightning-induced surges without degradation in standard PCB layouts |
| AEC-Q101 qualification | Validated for automotive applications including engine control units, body electronics, and ADAS sensor modules |
| Bi-directional symmetry | Eliminates need for polarity-aware layout; protects AC signals, differential buses (e.g., RS-485), and ungrounded sensors |
| RoHS-compliant, JESD201 Class 1A whisker-tested | Enables use in high-reliability industrial and medical-adjacent equipment with long-term solder joint integrity |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from ISO 7637-2 pulses and ESD events in vehicle ECUs. IC Role / Device Role / Timing Role: Bi-directional voltage clamp placed between signal line and ground, responding within <1 ns to limit transient overvoltage. Use Value: Prevents latch-up or gate oxide damage in 12 V rail-connected transceivers by clamping to ≤16.7 V during 24 A surge events. |
Use Scenario: Safeguarding digital input channels of programmable logic controllers against field-wiring induced surges and contact bounce. IC Role / Device Role / Timing Role: Standoff protector on 24 V DC input lines, conducting only when transients exceed 10.2 V. Use Value: Maintains system uptime by absorbing 400 W surges without failure, eliminating need for external fusing or resettable PTCs. |
| Consumer Appliance Motor Control | Telecom Line Interface Protection |
Use Scenario: Shielding microcontroller GPIOs and gate drivers from inductive kickback in washing machine motor inverters. IC Role / Device Role / Timing Role: Fast-acting shunt element across MOSFET source-drain or gate-resistor node. Use Value: Limits VDS spikes to safe levels during PWM switching, preventing false triggering and cumulative dielectric stress. |
Use Scenario: Front-end protection for Ethernet PHYs and DSL line drivers exposed to lightning-induced longitudinal surges. IC Role / Device Role / Timing Role: Primary surge limiter on twisted-pair lines, coordinated with GDT or MOV secondary stages. Use Value: Provides low-capacitance (<50 pF), low-leakage clamping that preserves signal integrity up to 100 MHz bandwidth. |
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 | Same DO-214AA package; higher 600 W PPPM but larger footprint; VC = 17.0 V at 34.4 A | Better suited for space-constrained board areas where DO-41 lead spacing is incompatible | Select SMBJ10CA if PCB layout requires surface-mount and thermal mass supports higher IPPM |
| P6KE10CA | DO-15 package; lower 600 W rating but same VWM/VC specs; higher VF and less stable VBR tempco (0.1 %/°C) | Legacy through-hole alternative with wider lead spacing; not AEC-Q101 qualified | Choose P6KE10CA only for cost-sensitive non-automotive designs where qualification is not required |
Compared with SMBJ10CA and P6KE10CA, BZW04P10-E3/54 offers AEC-Q101 validation, tighter VBR tolerance (±10 % vs ±15 %), lower temperature coefficient (0.078 %/°C), and optimized DO-41 mechanical robustness for high-vibration environments - making it the preferred choice for automotive and industrial Grade-A deployments.

FAQ
What is the clamping voltage of BZW04P10-E3/54 under a 10/1000 µs surge?
The BZW04P10-E3/54 clamps to a maximum of 16.7 V when subjected to a 24.0 A peak pulse current with a 10/1000 µs waveform. This value is guaranteed per Vishay's datasheet (Document Number: 88316, Rev. 12-Jul-11) and reflects worst-case device behavior at TA = 25 °C - critical for ensuring downstream 12 V ICs remain within absolute maximum ratings during surge events.
Is BZW04P10-E3/54 suitable for automotive applications?
Yes, BZW04P10-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use. Its construction - glass-passivated junction, DO-204AL package, and operation from –55 °C to +175 °C - meets requirements for engine control, body electronics, and ADAS sensor protection. The "HE3" variant (BZW04P10HE3/54) denotes full AEC-Q101 qualification, while the "E3" suffix indicates RoHS-compliant commercial grade with identical electrical specs.
Does BZW04P10-E3/54 have polarity markings?
No, BZW04P10-E3/54 is a bi-directional TVS diode and carries no polarity marking - consistent with Vishay's designation convention where "B" suffix (e.g., BZW04P10B) indicates bi-directionality and absence of cathode band. Both leads are functionally identical, enabling simplified layout and elimination of orientation errors during assembly.
What is the maximum steady-state power dissipation of BZW04P10-E3/54?
The BZW04P10-E3/54 has a maximum power dissipation (PD) of 1.5 W when mounted on an infinite heatsink at TL = 75 °C, as specified in the Absolute Maximum Ratings table. This rating applies to continuous DC or low-duty-cycle conditions - not transient suppression. For sustained operation, derating per Figure 5 of the datasheet is required above 25 °C ambient.
How does the temperature coefficient affect BZW04P10-E3/54's breakdown voltage?
The BZW04P10-E3/54 exhibits a maximum temperature coefficient of 0.078 %/°C for its breakdown voltage (VBR), meaning VBR increases by ≤0.078 % per °C rise in junction temperature. At +125 °C, VBR shifts no more than +7.8 % from its 25 °C value (11.4–13.2 V), ensuring predictable clamping behavior across automotive and industrial temperature ranges.
