Product details
Overview
BZW04-102-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 102 V standoff voltage (VWM), 114–126 V breakdown voltage (VBR) at 1 mA test current, 165 V maximum clamping voltage (VC) at 2.4 A peak pulse current (IPPM), and 400 W peak pulse power (PPPM) with 10/1000 μs waveform - used to protect MOSFETs, sensor interfaces, and industrial control inputs against ESD and inductive switching surges.
For engineers reviewing the BZW04-102-E3/54 datasheet, BZW04-102-E3/54 pinout, BZW04-102-E3/54 application, or BZW04-102-E3/54 equivalent, this device serves as a RoHS-compliant, AEC-Q101-qualified transient suppressor for bidirectional protection in automotive, industrial, and telecom systems where precise clamping level and low leakage (<1 μA at VWM) are critical.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling suppression of positive and negative transients without polarity constraints. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance, supporting fast response time (<1 ns) and repeatable clamping performance under repetitive 0.01% duty cycle pulses.
The device complies with ANSI/IEEE C62.35 surge standards and is rated for -55 °C to +175 °C operating junction temperature. Its 1.5 W steady-state power dissipation (PD) and 400 W peak pulse capability allow integration into compact PCB layouts without active thermal management in most applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 102 V - maximum continuous reverse working voltage before conduction begins; defines safe operating margin for normal circuit operation. |
| VBR min/max | 114 V / 126 V at 1 mA - verified breakdown range ensures predictable turn-on during overvoltage events. |
| VC @ IPPM | 165 V at 2.4 A - clamping voltage limits downstream component stress during 10/1000 μs transients. |
| PPPM | 400 W - peak pulse power handling capacity per standard 10/1000 μs waveform, enabling robust surge immunity. |
| ID @ VWM | <1 μA - ultra-low reverse leakage preserves signal integrity and minimizes standby power loss. |
| TJ max | +175 °C - high junction temperature rating supports reliability in under-hood automotive and industrial environments. |
| Package | DO-41 (DO-204AL) - axial-leaded through-hole package compatible with legacy assembly processes and manual repair. |
Pinout & Package
DO-41 (DO-204AL) package: axial-leaded, molded epoxy body with matte tin-plated leads; no polarity marking for bidirectional configuration; lead spacing 0.375" (9.5 mm); body diameter 0.107–0.160" (2.7–4.1 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both terminals function identically in bidirectional mode; no cathode band marking required. |
| Lead 1 / Lead 2 | PCB interconnect interface | Matte tin-plated, solderable per J-STD-002; withstands 275 °C dip for 10 s (JESD 22-B106). |
Key Features
| Feature | Design Value |
|---|---|

| 400 W peak pulse power (10/1000 μs) | Supports IEC 61000-4-5 Level 4 surge immunity without derating in typical board-level layouts. |
| AEC-Q101 qualified | Validated for automotive powertrain and chassis applications requiring zero defects and extended temperature operation. |
| UL 94 V-0 molding compound | Provides flame-retardant encapsulation essential for industrial safety certifications and enclosed system designs. |
| Low temperature coefficient of VBR | 0.107 %/°C - minimal drift across -55 °C to +175 °C enables consistent clamping in wide-temperature environments. |
Applications
| Automotive Sensor Protection | Industrial PLC Input Protection |
|---|---|
Use Scenario: Protecting CAN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and ESD in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional clamping element placed across differential or single-ended signal lines upstream of IC input pins. Use Value: Limits transient voltage to ≤165 V during 10/1000 μs surges, preventing latch-up or gate oxide damage in 5 V/12 V sensor interface ICs. |
Use Scenario: Shielding digital input modules in programmable logic controllers from inductive kickback caused by relay or solenoid switching. IC Role / Device Role / Timing Role: Parallel-connected transient suppressor on 24 V DC input rails feeding optocoupler or Schmitt-trigger front ends. Use Value: Clamps 400 W surges within 1 ns, maintaining <1 μA leakage at 102 V to avoid false triggering in high-impedance input circuits. |
| Telecom Line Interface Protection | Consumer Power Adapter Surge Suppression |
Use Scenario: Safeguarding Ethernet PHYs and DSL line drivers against lightning-induced surges on twisted-pair telecom lines. IC Role / Device Role / Timing Role: Primary-level TVS on line-side transformer secondary windings or RJ-45 jack returns. Use Value: Delivers 165 V clamping at 2.4 A while meeting IEC 61000-4-5 surge immunity requirements for Class B equipment. |
Use Scenario: Secondary-side overvoltage protection in AC/DC adapters for smart home devices exposed to mains-borne transients. IC Role / Device Role / Timing Role: Standoff-rated suppressor across DC output rails (e.g., 12 V or 19 V) before LDO regulators. Use Value: Maintains 102 V working margin while absorbing 400 W pulses, preventing regulator overvoltage shutdown and capacitor overstress. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A | Unidirectional; SMA package; 100 V VWM; 170 V VC @ 2.5 A; 600 W PPPM | Requires polarity-aware layout; surface-mount only; higher peak power but lower thermal mass | Select when higher surge rating is needed and unidirectional protection suffices with SMT assembly. |
| P6KE100A | Unidirectional; DO-15 package; 100 V VWM; 170 V VC @ 2.5 A; 600 W PPPM; no AEC-Q101 qualification | Larger DO-15 footprint; lacks automotive qualification; identical clamping but higher leakage (5 μA) | Choose for cost-sensitive industrial applications where AEC-Q101 is not required and board space allows DO-15. |
Compared with BZW04-102-E3/54, SMBJ100A offers higher peak power in a smaller SMT package but requires polarity awareness and lacks bidirectional symmetry, while P6KE100A matches mechanical form factor but omits automotive qualification and exhibits five times higher leakage - making BZW04-102-E3/54 optimal for bidirectional, AEC-Q101-compliant, low-leakage through-hole designs.

FAQ
What is the polarity configuration of BZW04-102-E3/54?
BZW04-102-E3/54 is a bidirectional TVS diode, meaning it provides symmetrical clamping for both positive and negative transients without cathode/anode distinction. No color band or marking is present on the DO-41 package, confirming its bidirectional functionality as specified in the Vishay datasheet revision 16-Sep-2021.
Does BZW04-102-E3/54 meet AEC-Q101 qualification?
Yes, BZW04-102-E3/54 meets AEC-Q101 qualification, as confirmed in the Vishay document 88316 (revision 16-Sep-2021), footnote (1) under Ratings and Characteristics Curves. This qualification validates its suitability for automotive powertrain and chassis applications requiring zero defects and extended temperature operation.
What is the maximum clamping voltage for BZW04-102-E3/54 under surge conditions?
The maximum clamping voltage (VC) for BZW04-102-E3/54 is 165 V at 2.4 A peak pulse current (IPPM), measured using the standard 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during transient events.
Can BZW04-102-E3/54 be used in surface-mount designs?
No, BZW04-102-E3/54 uses a DO-41 (DO-204AL) axial-leaded through-hole package and is not suitable for surface-mount assembly. For SMT alternatives with similar electrical specs, consider SMBJ100A or SMCJ100A - but note these are unidirectional and require polarity-aware placement.
What is the reverse leakage current specification for BZW04-102-E3/54 at its standoff voltage?
At its 102 V standoff voltage (VWM), BZW04-102-E3/54 exhibits a maximum reverse leakage current (ID) of 1.0 μA at 25 °C, as specified in the Electrical Characteristics table of the Vishay datasheet. This ultra-low leakage preserves signal integrity and minimizes power loss in high-impedance protection circuits.
