Product details
Overview
BZW04P33HE3/54 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 33.3 V stand-off voltage (VWM), 53.9 V clamping voltage (VC) at 7.4 A peak pulse current, and 400 W peak pulse power capability with 10/1000 μs waveform - deployed in automotive sensor interfaces, industrial I/O modules, and telecom line protection.
For engineers reviewing the BZW04P33HE3/54 datasheet, BZW04P33HE3/54 pinout, BZW04P33HE3/54 application, or BZW04P33HE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, DO-41 package compatibility, bi-directional clamping symmetry, and low 0.1 % duty cycle surge handling for inductive switching transients.
Technical Context
This bi-directional TVS diode operates symmetrically in both polarities, with breakdown voltage (VBR) specified between 37.1 V and 42.9 V at 1 mA test current. Its clamping performance is validated at 7.4 A (10/1000 μs), delivering 53.9 V maximum across the terminals under surge conditions.
Thermally rated for -55 °C to +175 °C junction operation and qualified per AEC-Q101, it supports high-reliability automotive environments. The device uses glass-passivated chip junction construction and matte tin-plated leads compliant with J-STD-002 and JESD22-B102 solderability standards.

|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from ESD and load dump transients in vehicle ECUs. IC Role / Device Role / Timing Role: Standby clamping element placed directly at connector entry point to shunt surge energy before reaching sensitive ASICs. Use Value: Limits induced voltage to ≤53.9 V during 7.4 A transients, preserving signal integrity and preventing latch-up in 3.3 V/5 V microcontrollers. | Use Scenario: Safeguarding digital input channels on programmable logic controllers exposed to relay coil flyback and motor drive noise. IC Role / Device Role / Timing Role: Primary front-end transient suppressor on 24 V DC input lines, coordinated with upstream fusing and filtering. Use Value: Absorbs 400 W surges without degradation, maintaining <1 μA leakage at 33.3 V to avoid false triggering in high-impedance sensing circuits. |
| Telecom Line Interface | Consumer Appliance Motor Control |
Use Scenario: Shielding Ethernet PHYs and DSL line drivers from lightning-induced surges on outdoor-facing ports. IC Role / Device Role / Timing Role: Secondary-level protector downstream of gas discharge tubes (GDTs), providing fast-response clamping after coarse suppression. Use Value: Sub-1 ns response time ensures clamping occurs before voltage exceeds IC absolute maximum ratings, even with fast-rising transients. | Use Scenario: Protecting MCU GPIOs and gate drivers in washing machine or HVAC blower modules from brush-commutator spikes. IC Role / Device Role / Timing Role: Localized TVS on motor driver enable lines and feedback paths to prevent reset or damage during commutation events. Use Value: AEC-Q101 qualification guarantees operational stability across -40 °C to +125 °C ambient, matching appliance thermal profiles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ33CA | DO-214AA package (SMB), 33 V VWM, 53.3 V VC @ 7.5 A, same 400 W rating | Surface-mount footprint; requires PCB rework for through-hole replacement | Select when board space is constrained and reflow assembly is preferred over axial-leaded hand-soldering. |
| P6KE33CA | DO-15 package, 33.2 V VWM, 53.3 V VC @ 7.5 A, 600 W PPPM rating | Higher surge margin but larger body; not AEC-Q101 qualified | Choose for cost-sensitive industrial applications where automotive qualification is unnecessary and higher pulse tolerance is required. |
Compared with BZW04P33HE3/54, SMBJ33CA offers identical electrical protection in a compact SMD form factor but lacks AEC-Q101 validation, while P6KE33CA provides greater pulse power headroom in a legacy through-hole package but omits automotive reliability certification - making BZW04P33HE3/54 the optimal choice for AEC-compliant designs requiring proven DO-41 integration.

FAQ
What is the clamping voltage of BZW04P33HE3/54 under standard surge conditions?
The BZW04P33HE3/54 exhibits a maximum clamping voltage (VC) of 53.9 V when subjected to a 10/1000 μs waveform with a peak pulse current (IPPM) of 7.4 A. This value is measured per JEDEC standards and ensures downstream circuitry remains within safe operating limits during transient events. The BZW04P33HE3/54 maintains this clamping performance across its full operating temperature range.
Is BZW04P33HE3/54 suitable for automotive applications?
Yes, BZW04P33HE3/54 is AEC-Q101 qualified and explicitly rated for automotive use. Its construction - including glass-passivated junction, matte tin-plated leads, and DO-41 package qualified to UL 94 V-0 - meets stringent automotive reliability requirements. The BZW04P33HE3/54 is commonly deployed in engine control units, body electronics, and ADAS sensor interfaces where transient immunity is critical.
What does the "HE3/54" suffix indicate in BZW04P33HE3/54?
The "HE3" suffix denotes RoHS-compliant, AEC-Q101-qualified version with JESD201 Class 2 whisker resistance; "54" specifies the preferred packaging code - 13-inch paper tape and reel, 550 units per reel. This distinguishes BZW04P33HE3/54 from commercial-grade variants (e.g., E3-only) and confirms its suitability for high-reliability production. The BZW04P33HE3/54 ordering code ensures traceable, automotive-grade material flow.
How does BZW04P33HE3/54 differ from uni-directional TVS diodes like BZW04P33E3/54?
BZW04P33HE3/54 is bi-directional, meaning it clamps symmetrically for both positive and negative transients - ideal for AC lines or floating signals. In contrast, uni-directional variants (e.g., BZW04P33E3/54) have a cathode band and only conduct in reverse bias; forward conduction follows standard diode behavior. The BZW04P33HE3/54 eliminates polarity concerns in differential or bidirectional interfaces, simplifying layout and reducing BOM count.
What is the maximum operating temperature for BZW04P33HE3/54?
The BZW04P33HE3/54 has a maximum junction temperature (TJ) of +175 °C and an operating junction/storage temperature range of -55 °C to +175 °C. This wide thermal envelope supports under-hood automotive placement and high-ambient industrial environments. Derating curves in the datasheet (Fig. 2 and Fig. 5) define power and current limits above 25 °C ambient - essential for thermal design validation of the BZW04P33HE3/54.
