Product details
Overview
BZW04P53BHE3/73 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 stand-off voltage (VWM), 85.0 V maximum clamping voltage (VC) at 4.7 A peak pulse current (IPPM), and 400 W peak pulse power (PPPM) capability with 10/1000 μs waveform - deployed to safeguard MOSFETs, ICs, and sensor interfaces against ESD and inductive switching transients.
For engineers reviewing the BZW04P53BHE3/73 datasheet, BZW04P53BHE3/73 pinout, BZW04P53BHE3/73 application, or BZW04P53BHE3/73 equivalent, key selection criteria include its AEC-Q101 qualification, DO-204AL (DO-41) package compatibility, bi-directional symmetry, low 0.104 %/°C temperature coefficient of breakdown voltage, and 1.0 μA max reverse leakage at VWM - critical for automotive and industrial reliability-critical designs.
Technical Context
This bi-directional TVS diode 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 10/1000 μs transients.
The device is rated for 400 W peak pulse power per IEC 61000-4-5 (10/1000 μs), derated above 25 °C per Fig. 2, and supports operating junction temperatures from –55 °C to +175 °C. It meets JESD22-B106 solder dip (275 °C, 10 s) and JESD201 class 2 whisker testing (HE3 suffix), confirming suitability for high-reliability reflow and wave-solder processes.
Key Specifications

Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting LIN bus transceivers and power supply rails in vehicle door modules exposed to load dump and alternator ripple. IC Role / Device Role / Timing Role: Bi-directional TVS clamp absorbing ±100 V transients while maintaining <1.0 μA leakage at 13.5 V nominal system voltage. Use Value: Prevents latch-up and gate oxide damage in 3.3 V/5 V microcontrollers and CAN/LIN PHYs without adding series impedance or propagation delay. |
Use Scenario: Shielding 4–20 mA current loop inputs and RS-485 transceivers in PLC I/O modules from field-induced surges and ESD. IC Role / Device Role / Timing Role: Standoff-rated suppression element placed directly at connector entry point, clamping transients before they reach isolation barriers or ADC front-ends. Use Value: Maintains signal fidelity with <1 pF junction capacitance at zero bias (per Fig. 4), avoiding bandwidth reduction in 1 MHz analog sensor channels. |
| Consumer Equipment Surge Suppression | Telecom Line Interface Protection |
Use Scenario: Safeguarding USB-C power delivery (PD) controller ICs and buck-boost converters in portable chargers subjected to hot-plug and cable discharge events. IC Role / Device Role / Timing Role: Fast-response (sub-nanosecond) clamping device placed between input capacitor and DC-DC stage to limit voltage overshoot during transient coupling. Use Value: Enables compact design by replacing multi-stage protection with single-device solution - reduces BOM count and board space vs. MOV+TVS cascades. |
Use Scenario: Protecting Ethernet PHYs and PoE injectors in network switches against lightning-induced surges on RJ-45 ports per IEC 61000-4-5. IC Role / Device Role / Timing Role: Primary line-side TVS in common-mode choke + TVS architecture, handling differential and common-mode transients up to 4 kV. Use Value: Delivers repeatable 85.0 V clamping at 4.7 A with <0.104 %/°C VBR drift - ensuring consistent protection margin across outdoor temperature ranges (–40 °C to +85 °C). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ53AHE3/52 | Same DO-214AA package; 53 V VWM but unidirectional; VF = 3.5 V; lower 600 W PPPM rating. | Requires polarity-aware placement; unsuitable for AC or floating lines; better for DC rail protection with tighter clamping (VC = 87 V @ 5.2 A). | Select when protecting regulated 48 V DC supplies where polarity is fixed and higher peak power margin is needed. |
| 1.5KE56A | DO-201AD package; 56 V VWM; 1500 W PPPM; higher VC = 93.6 V @ 16.6 A; no AEC-Q101 qualification. | Larger footprint; higher clamping voltage increases risk to 3.3 V logic; lacks automotive qualification and RoHS HE3 traceability. | Consider only for cost-sensitive industrial mains-input protection where AEC-Q101 and compact size are not required. |
Compared with SMBJ53AHE3/52 and 1.5KE56A, BZW04P53BHE3/73 uniquely combines bi-directional symmetry, AEC-Q101 qualification, DO-41 form factor, and precise 53.0 V VWM - making it the optimal choice for space-constrained, automotive-grade, polarity-agnostic transient protection.

FAQ
What is the clamping voltage of BZW04P53BHE3/73 and how is it measured?
The BZW04P53BHE3/73 has a maximum clamping voltage (VC) of 85.0 V, measured at a peak pulse current (IPPM) of 4.7 A using a 10/1000 μs waveform per IEC 61000-4-5. This value represents the upper voltage limit imposed on protected circuitry during a standardized surge event and is guaranteed across the full operating temperature range (–55 °C to +175 °C).
Is BZW04P53BHE3/73 suitable for automotive applications?
Yes, BZW04P53BHE3/73 is AEC-Q101 qualified (as indicated by the HE3 suffix) and tested to automotive stress requirements including temperature cycling, humidity bias, and mechanical shock. Its DO-204AL package, 175 °C TJ max, and JESD201 class 2 whisker resistance make it appropriate for under-hood and chassis-mounted ECUs, sensor nodes, and body control modules.
How does the bi-directional nature of BZW04P53BHE3/73 affect its use in circuit design?
The bi-directional structure of BZW04P53BHE3/73 means it provides symmetrical clamping in both polarities - eliminating the need for polarity identification during placement and enabling protection of AC-coupled signals, differential buses (e.g., RS-485), or floating grounds. No color band marking is present, and either lead may connect to either side of the protected line.
What is the significance of the HE3 suffix in BZW04P53BHE3/73?
The HE3 suffix denotes that BZW04P53BHE3/73 is RoHS-compliant and AEC-Q101 qualified, with matte tin-plated leads meeting JESD201 class 2 whisker resistance (vs. E3's class 1A). It also indicates packaging in 13" paper tape and reel (73 = 550 pcs/reel), and compliance with J-STD-002 solderability and JESD22-B106 solder dip standards.
Can BZW04P53BHE3/73 be used in parallel for higher surge current handling?
No - BZW04P53BHE3/73 is not recommended for parallel operation due to parameter spread in VBR (58.9–68.2 V) and dynamic impedance, which causes uneven current sharing and potential thermal runaway. For higher IPPM requirements, select a single higher-rated device such as BZW04P85BHE3/73 (IPPM = 2.9 A) or consult Vishay's application note AN1003 on TVS derating.
