Product details
Overview
BZW04-23-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on signal or power lines. It features a 23.1 V standoff voltage (VWM), 25.7–28.4 V breakdown voltage (VBR) at 1 mA, 37.5 V clamping voltage (VC) at 10.7 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, sensor interfaces, and industrial I/O circuits.
For engineers reviewing the BZW04-23-E3/54 datasheet, BZW04-23-E3/54 pinout, BZW04-23-E3/54 application, or BZW04-23-E3/54 equivalent, this page delivers verified electrical parameters, DO-41 terminal mapping, AEC-Q101 qualification status, bidirectional clamping behavior, and direct alternatives for overvoltage protection design in automotive and industrial environments.
Technical Context
This device operates as a bidirectional avalanche diode, symmetrically clamping positive and negative transients without polarity dependence. Its glass-passivated junction ensures stable VBR temperature coefficient (0.096 %/°C) and low incremental surge resistance, enabling consistent clamping under repetitive 10/1000 μs pulses at 0.01 % duty cycle.
Designed for unclamped inductive switching events and lightning-induced surges, it delivers 37.5 V clamping at 10.7 A while maintaining ≤1.0 μA reverse leakage at 23.1 V - critical for low-power sensor line protection where standby current integrity matters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 23.1 V - maximum continuous reverse voltage before significant leakage; defines safe operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 25.7–28.4 V at 1 mA - precise avalanche onset range ensuring predictable turn-on during transients |
| VC (Clamping Voltage) | 37.5 V at IPPM = 10.7 A - peak voltage seen by protected circuit during worst-case 400 W transient |
| PPPM (Peak Pulse Power) | 400 W - energy-handling capacity per 10/1000 μs waveform, derated above 25 °C per Fig. 2 |
| ID (Reverse Leakage) | ≤1.0 μA at 23.1 V - negligible standby current impact on high-impedance sensor or logic inputs |
| TJ max. | +175 °C - enables operation in under-hood automotive or high-temperature industrial enclosures |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with axial leads; no polarity marking for bidirectional configuration - both terminals are functionally identical under transient stress.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction | No cathode band; either lead serves as transient sink for ± polarity events - simplifies PCB layout vs. unidirectional TVS |
| Lead 1 | External connection point | Matte tin-plated, solderable per J-STD-002; supports 275 °C / 10 s solder dip per JESD22-B106 |
| Lead 2 | External connection point | Identical to Lead 1; no functional distinction - enables placement in either orientation on board |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling and humidity exposure |
| 400 W peak pulse power (10/1000 μs) | Handles common IEC 61000-4-5 surge events without degradation when properly heatsinked |
| AEC-Q101 qualification | Validated for automotive powertrain, body electronics, and ADAS sensor protection applications |
| UL 94 V-0 molding compound | Meets flammability safety requirements for enclosed industrial and transportation equipment |
| Low 0.096 %/°C VBR tempco | Minimizes clamping voltage drift across -55 °C to +175 °C operating range |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional clamping element placed directly at connector entry point to shunt transients before reaching sensitive ICs. Use Value: Maintains 23.1 V standoff while clamping to 37.5 V - preserves signal integrity of 24 V sensor supplies and avoids false triggering of downstream comparators. |
Use Scenario: Safeguarding digital input modules in programmable logic controllers exposed to relay coil flyback and motor drive noise. IC Role / Device Role / Timing Role: Fast-response transient suppressor across 24 V DC input terminals to prevent latch-up or damage to optocoupler input stages. Use Value: Sub-100 ns response time and 400 W pulse handling enable reliable suppression of 100–500 V, 1–2 A inductive spikes without derating. |
| Telecom Line Interface | Consumer Appliance Motor Control |
Use Scenario: Shielding RS-485 transceivers and Ethernet PHYs from ESD and lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: Primary front-end TVS on differential data lines, paired with common-mode chokes for full-spectrum immunity. Use Value: Symmetric clamping eliminates need for dual unidirectional devices - reduces BOM count and layout area in space-constrained telecom modules. |
Use Scenario: Protecting gate drivers and microcontrollers in washing machine motor inverters from MOSFET switching transients. IC Role / Device Role / Timing Role: Clamp diode across DC bus or gate-source nodes to absorb voltage overshoot during hard-switching events. Use Value: 175 °C max junction temperature rating allows mounting near heat-generating power stages without thermal derating penalties. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24CA | DO-214AA package; 24 V VWM; 38.9 V VC at 10.3 A; same 400 W PPPM rating | Surface-mount footprint - requires PCB redesign; higher thermal resistance than axial DO-41 in free-air | Select when automated SMT assembly is required and board space is constrained; verify thermal relief for >1 W steady-state dissipation |
| P6KE27CA | DO-15 package; 27 V VWM; 43.0 V VC at 9.3 A; 600 W PPPM (10/1000 μs) | Higher clamping voltage and larger case - less suitable for 24 V systems with tight voltage margins | Choose only if system can tolerate ≥43 V transient clamp level and needs higher single-pulse energy absorption |
Compared with BZW04-23-E3/54, SMBJ24CA offers SMT compatibility but sacrifices axial lead mechanical robustness and thermal performance in non-heatsinked layouts; P6KE27CA provides greater pulse energy headroom at the cost of looser voltage control - making BZW04-23-E3/54 optimal for cost-sensitive, through-hole 24 V industrial and automotive protection where precise clamping and AEC-Q101 compliance are mandatory.

FAQ
What is the polarity configuration of BZW04-23-E3/54?
BZW04-23-E3/54 is a bidirectional TVS diode with symmetrical avalanche characteristics - neither lead is marked as anode or cathode, and it clamps equally for positive and negative transients. This eliminates orientation concerns during placement and simplifies design for AC-coupled or differential signal lines.
Is BZW04-23-E3/54 qualified for automotive use?
Yes, BZW04-23-E3/54 carries AEC-Q101 qualification (as indicated by the HE3 suffix variant), confirming its suitability for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. The E3/54 variant is commercial grade but shares identical electrical specs and DO-41 packaging.
What does the "E3/54" suffix mean in BZW04-23-E3/54?
The "E3" denotes RoHS-compliant matte tin plating meeting JESD201 Class 1A whisker resistance, while "/54" specifies the preferred packaging code: 13-inch paper tape and reel with 550 units per reel. This format ensures compatibility with standard pick-and-place equipment for high-volume manufacturing.
How does BZW04-23-E3/54 compare to unidirectional TVS diodes like BZW04-23?
BZW04-23-E3/54 provides identical VWM (23.1 V), VBR (25.7–28.4 V), and VC (37.5 V) specs as its unidirectional counterpart but adds symmetrical clamping for bipolar transients. Unlike unidirectional versions, it requires no polarity awareness during layout and avoids forward conduction issues on AC signals or floating grounds.
What is the maximum junction temperature rating for BZW04-23-E3/54?
The maximum junction temperature (TJ max.) for BZW04-23-E3/54 is +175 °C, enabling reliable operation in under-hood automotive environments or sealed industrial enclosures. Derating begins above 25 °C ambient per Figure 2 in the datasheet, with 100 % power capability only at TA ≤ 25 °C.
