Product details
Overview
BZW04P23HE3/54 from Vishay General Semiconductor is a bi-directional TransZorb® transient voltage suppressor (TVS) diode in DO-204AL (DO-41) package, designed for clamping ESD and surge transients on signal/power lines. It features 400 W peak pulse power (10/1000 µs), 23.1 V stand-off voltage (VWM), 37.5 V maximum clamping voltage (VC) at 10.7 A peak pulse current, and AEC-Q101 qualification for automotive electronics protection.
For engineers reviewing the BZW04P23HE3/54 datasheet, BZW04P23HE3/54 pinout, BZW04P23HE3/54 application, or BZW04P23HE3/54 equivalent, key selection criteria include its bi-directional clamping symmetry, low leakage (<1 µA at 23.1 V), 0.096 %/°C VBR temperature coefficient, and suitability for I/O line protection in harsh environments where repetitive surge immunity and automotive-grade reliability are required.
Technical Context
This device operates as a voltage-clamped shunt protector: during overvoltage events exceeding its breakdown threshold (25.7–29.7 V at 1 mA), it avalanches to divert surge current away from downstream circuitry. Its glass-passivated junction ensures stable breakdown and low incremental surge resistance, enabling fast response (<1 ns) and consistent clamping performance across temperature.
The bi-directional configuration supports AC-coupled or floating signal paths without polarity constraints, while the DO-204AL package provides mechanical robustness and thermal dissipation capability up to 1.5 W continuous power. AEC-Q101 qualification confirms its suitability for automotive under-hood and infotainment applications requiring extended temperature operation (−55 °C to +175 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 23.1 V - Maximum continuous reverse operating voltage before conduction begins; defines safe working margin for 24 V nominal systems. |
| VBR (min/max) | 25.7 V / 29.7 V at 1 mA - Breakdown voltage range ensuring reliable avalanche initiation across process and temperature variation. |
| VC @ IPPM | 37.5 V at 10.7 A - Clamping voltage during 10/1000 µs surge; limits stress on protected ICs to safe levels. |
| PPPM | 400 W - Peak pulse power handling capacity; enables protection against IEC 61000-4-5 Level 3 surges (1 kV/2 Ω). |
| IDRM | <1 µA at VWM - Ultra-low reverse leakage preserves signal integrity and battery life in always-on circuits. |
| TJ max | +175 °C - Junction temperature rating supporting under-hood automotive deployment without derating. |

Applications
| Automotive Sensor Interface Protection | Industrial PLC Analog Input Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor front-ends (e.g., pressure, temperature) from load dump and ESD in vehicle ECUs. IC Role / Device Role / Timing Role: Bi-directional shunt TVS placed directly at connector entry point to clamp transients before reaching signal conditioning circuitry. Use Value: Prevents false triggering and permanent damage to 24 V-rated microcontrollers and op-amps by limiting clamped voltage to ≤37.5 V during 10.7 A surges. |
Use Scenario: Safeguarding 4–20 mA current loop inputs and ±10 V analog inputs in programmable logic controllers exposed to field wiring surges. IC Role / Device Role / Timing Role: Standoff voltage (23.1 V) matches common industrial supply rails; clamps fast transients without affecting normal signal fidelity. Use Value: Enables >100,000 surge cycles without parameter shift due to glass-passivated junction stability and low leakage (<1 µA). |
| Consumer Audio Line Protection | Telecom DSL/ADSL Line Interface |
Use Scenario: Shielding headphone jack, microphone input, and speaker outputs in portable audio devices from human-body ESD (±8 kV contact). IC Role / Device Role / Timing Role: Bi-directional clamping element placed inline with unbalanced audio traces to suppress sub-100 ns ESD pulses. Use Value: Sub-1 ns response time and <1 µA leakage preserve audio SNR and battery runtime in always-on portable designs. |
Use Scenario: Protecting ADSL line drivers and receivers from induced surges on twisted-pair telephone lines in residential gateways. IC Role / Device Role / Timing Role: Paired with common-mode chokes to suppress differential-mode surges on xDSL data pairs without loading signal bandwidth. Use Value: 37.5 V clamping voltage aligns with ITU-T K.21 recommendations for class B telecom equipment surge immunity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24CA | DO-214AA package; 24 V VWM, 38.9 V VC @ 10.3 A; same 400 W PPPM but higher thermal resistance (RθJA ≈ 70 °C/W vs. DO-41's ~50 °C/W). | Preferred for surface-mount layouts; less suitable for through-hole legacy designs or high-temperature ambient (>105 °C). | Select SMBJ24CA only when SMT assembly is mandatory and board space is constrained. |
| 1.5KE24CA | DO-201AE package; 24 V VWM, 38.9 V VC @ 10.3 A; 1500 W PPPM but larger footprint and slower response due to higher junction capacitance (~150 pF vs. ~50 pF). | Better for high-energy surges (e.g., AC mains coupling); over-specified for fast ESD where low capacitance is critical. | Choose 1.5KE24CA only when surge energy exceeds 400 W requirements and layout allows larger case size. |
Compared with SMBJ24CA and 1.5KE24CA, BZW04P23HE3/54 offers optimal balance of axial-leaded manufacturability, AEC-Q101 qualification, low capacitance, and thermal performance in cost-sensitive automotive and industrial through-hole designs.

FAQ
What is the polarity configuration of BZW04P23HE3/54?
BZW04P23HE3/54 is a bi-directional TVS diode with symmetrical avalanche characteristics in both forward and reverse bias. It has no cathode marking and may be installed in either orientation on the PCB, making it ideal for AC-coupled or floating signal lines where polarity is undefined or variable.
Does BZW04P23HE3/54 meet automotive qualification standards?
Yes, BZW04P23HE3/54 carries the HE3 suffix, indicating AEC-Q101 qualification. This includes stress testing for high-temperature operating life, temperature cycling, unbiased highly accelerated stress testing, and ESD per JS-001, confirming suitability for automotive powertrain, chassis, and body electronics applications.
What is the maximum clamping voltage of BZW04P23HE3/54 under surge conditions?
The maximum clamping voltage (VC) of BZW04P23HE3/54 is 37.5 V at 10.7 A peak pulse current with a 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and ensures protected ICs experience minimal overvoltage stress during standardized surge events.
How does the HE3 suffix differ from the E3 suffix in BZW04P23HE3/54?
The HE3 suffix denotes AEC-Q101 qualification and JESD201 Class 2 whisker resistance, whereas E3 indicates commercial-grade RoHS compliance only. BZW04P23HE3/54 is tested to automotive reliability standards and rated for operation up to +175 °C junction temperature, unlike E3 variants limited to +150 °C.
Can BZW04P23HE3/54 be used in place of uni-directional TVS diodes?
No - BZW04P23HE3/54 is strictly bi-directional and must not replace uni-directional TVS diodes in DC-biased circuits (e.g., power rail clamping), as it conducts in both directions and lacks a defined cathode. For DC applications requiring polarity-aware clamping, a uni-directional part like BZW04P23E3/54 must be selected instead.
