Product details
Overview
BZW04P53BHE3/54 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 53.0 V standoff voltage (VWM), 85.0 V clamping voltage (VC) at 4.7 A peak pulse current (IPPM), and 400 W peak pulse power (10/1000 µs waveform), making it suitable for protecting automotive sensor interfaces and industrial I/O circuits against ESD and inductive switching transients.
For engineers reviewing the BZW04P53BHE3/54 datasheet, BZW04P53BHE3/54 pinout, BZW04P53BHE3/54 application, or BZW04P53BHE3/54 equivalent, this device delivers AEC-Q101-qualified surge immunity in DO-41 packaging with low leakage (<1 µA at VWM) and fast response time - critical for safeguarding CAN, LIN, and analog sensor front-ends in harsh environments.
Technical Context
This bi-directional TVS operates symmetrically in both polarities, with breakdown voltage (VBR) specified between 58.9 V and 68.2 V at 1 mA test current. Its clamping behavior is characterized by a maximum VC of 85.0 V under 4.7 A 10/1000 µs surge, ensuring predictable voltage limiting during transients.
The device exhibits a temperature coefficient of VBR of +0.104 %/°C and is rated for continuous operation from –55 °C to +175 °C junction temperature. It supports repetitive surge events at ≤0.01 % duty cycle and meets JESD22-B102 solderability standards with matte tin-plated leads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 53.0 V - Maximum continuous reverse operating voltage before clamping begins; defines safe working margin below breakdown. |
| VC @ IPPM | 85.0 V at 4.7 A - Clamped voltage during 10/1000 µs surge; determines maximum stress imposed on protected circuitry. |
| PPPM | 400 W - Peak pulse power handling capability; enables suppression of high-energy transients like ISO 7637-2 Pulse 1/2a/5a. |
| IPPM | 4.7 A - Peak pulse current supported at rated VC; correlates directly with surge energy absorption (E ≈ VC × IPPM × twidth). |
| TJ max | +175 °C - Maximum junction temperature; allows reliable operation in under-hood automotive and high-ambient industrial settings. |
| Leakage (ID) | <1 µA at VWM - Ultra-low reverse leakage preserves signal integrity and minimizes standby power loss in always-on circuits. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including HTOL, TC, UHAST, and ESD testing per AEC specification. |
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. Bi-directional polarity - no cathode marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bi-directional transient conduction path | No polarity distinction; either terminal serves as anode or cathode depending on transient polarity - simplifies PCB layout and eliminates orientation errors. |
| Lead 1 / Lead 2 | Connection to protected line and ground/reference | Placed across protected node (e.g., signal-to-ground); conducts only during overvoltage events >VWM, remaining high-impedance otherwise. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables stable, repeatable breakdown characteristics and long-term reliability under thermal cycling and humidity stress. |
| 400 W peak pulse power (10/1000 µs) | Supports automotive load-dump and inductive-switching surge standards without derating at TA ≤ 25 °C. |
| AEC-Q101 qualification | Validates suitability for automotive electronics including engine control units, body modules, and ADAS sensor interfaces. |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ESD), improving protection margin for downstream ICs. |
| RoHS-compliant, HE3 suffix | Indicates AEC-Q101 qualified, whisker-tested (JESD201 Class 2), and fully compliant with EU RoHS Directive 2011/65/EU. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ53A-E3/52 | Unidirectional; 53 V VWM, 87 V VC @ 4.6 A; SMB package (surface-mount) | Requires polarity-aware placement; better suited for PCB space-constrained SMT designs vs. through-hole DO-41. | Select when automated assembly and smaller footprint are prioritized over manual repairability or high-power leaded mounting. |
| 1.5KE56A | Unidirectional; 56 V VWM, 93.6 V VC @ 4.3 A; DO-201 package; 1500 W PPPM | Higher clamping voltage and larger package; intended for higher-energy surges but less precise voltage matching. | Choose for legacy designs requiring higher surge margin where 85 V clamping is insufficient and board real estate allows DO-201 size. |
Compared with SMBJ53A-E3/52 and 1.5KE56A, BZW04P53BHE3/54 offers bi-directional symmetry in a compact DO-41 through-hole package with tighter VC tolerance and AEC-Q101 validation - making it optimal for new automotive and industrial designs demanding polarity-agnostic protection and qualification traceability.

FAQ
What is the clamping voltage of BZW04P53BHE3/54 and why does it matter?
The BZW04P53BHE3/54 has a maximum clamping voltage (VC) of 85.0 V at 4.7 A peak pulse current (10/1000 µs waveform). This value defines the highest voltage that will appear across protected circuitry during a surge event - directly determining whether downstream components like microcontrollers or transceivers remain within their absolute maximum ratings. Lower VC improves protection margin, especially for 5 V or 3.3 V logic interfaces.
Is BZW04P53BHE3/54 suitable for automotive applications?
Yes, BZW04P53BHE3/54 is AEC-Q101 qualified and carries the HE3 suffix, confirming compliance with automotive reliability testing including high-temperature operating life, temperature cycling, and ESD. Its –55 °C to +175 °C operating range and DO-41 mechanical robustness make it appropriate for under-hood and body-control module applications where vibration and thermal stress are present.
How does the bi-directional design of BZW04P53BHE3/54 affect circuit implementation?
The bi-directional nature of BZW04P53BHE3/54 means it protects against both positive and negative transients without polarity constraints - eliminating the need to identify anode/cathode during placement. This simplifies PCB layout, reduces assembly errors, and enables use in AC-coupled or differential signal paths (e.g., LIN, RS-485 stubs) where voltage polarity reverses during normal operation or fault conditions.
What is the significance of the "HE3" suffix in BZW04P53BHE3/54?
The "HE3" suffix in BZW04P53BHE3/54 indicates RoHS-compliant construction with AEC-Q101 qualification and JESD201 Class 2 whisker resistance (tested per 1000-hour storage at 150 °C). It distinguishes this grade from commercial-only "E3" variants and confirms suitability for automotive production, including traceability, extended reliability screening, and enhanced plating integrity for long-term solder joint reliability.
Can BZW04P53BHE3/54 be used in place of a unidirectional TVS like SMBJ53A?
BZW04P53BHE3/54 can replace unidirectional TVS diodes in applications where polarity is undefined or bidirectional surges occur - such as across AC signal lines or floating sensor outputs. However, it should not substitute unidirectional parts in DC-biased circuits requiring forward conduction (e.g., power rail clamping), as its symmetrical IV curve lacks a defined forward voltage drop. Always verify system-level surge directionality before substitution.
