Product details
Overview
P4KE30AHE3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in DO-41 package, designed for clamping inductive switching surges and lightning-induced transients on power and signal lines. It features 30 V breakdown voltage (VBR min/max = 28.5–31.5 V), 25.6 V stand-off voltage (VWM), 400 W peak pulse power (10/1000 μs), 41.4 V maximum clamping voltage at 9.7 A, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the P4KE30AHE3/54 datasheet, P4KE30AHE3/54 pinout, P4KE30AHE3/54 application, or P4KE30AHE3/54 equivalent, this device is selected for robust overvoltage protection in DC power rails, sensor interfaces, and MOSFET gate drivers where fast response (<1 ns), low clamping ratio (VC/VBR ≈ 1.35), and stable thermal performance up to 175 °C junction temperature are required.
Technical Context
The P4KE30AHE3/54 operates as a silicon avalanche diode with glass-passivated junction, enabling precise, repeatable breakdown behavior under transient stress. Its unidirectional polarity-marked by cathode band-ensures defined conduction direction during surge events, and its 10/1000 μs waveform rating reflects standardized IEC 61000-4-5 surge immunity testing conditions.
Thermal design relies on DO-41's lead-to-junction thermal resistance (RθJL = 66 °C/W) and ambient resistance (RθJA = 100 °C/W), supporting operation from –55 °C to +175 °C. The device meets JESD 201 Class 2 whisker resistance and UL 94 V-0 flammability requirements, confirming suitability for high-reliability industrial and automotive PCB assemblies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 28.5 V / 31.5 V - defines guaranteed avalanche onset range at 1.0 mA test current; ensures consistent clamping threshold across production lots |
| VWM | 25.6 V - maximum continuous reverse working voltage; sets safe operating margin below breakdown for DC rail protection |
| VC @ IPPM | 41.4 V at 9.7 A - clamped voltage during 400 W transient; determines protected circuit's peak stress level |
| PPPM | 400 W - peak pulse power handling (10/1000 μs); validates compliance with IEC 61000-4-5 Level 4 surge immunity |
| IFSM | 40 A - 8.3 ms half-sine surge current rating; supports protection against inductive kickback in relay/actuator circuits |
| TJ max | +175 °C - maximum junction temperature; enables use in under-hood automotive environments without derating |
| Leakage @ VWM | 1.0 μA - ultra-low reverse leakage at stand-off voltage; minimizes standby power loss in battery-powered systems |
Pinout & Package
Package: DO-41 (DO-204AL), axial-leaded, molded epoxy body with matte tin-plated leads. Complies with J-STD-002/JESD 22-B102 solderability and UL 94 V-0 flammability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path); conducts during positive transients when cathode is at higher potential |
| Cathode (banded end) | Avalanche clamping terminal | Connected to protected line (e.g., 24 V rail); initiates avalanche breakdown when voltage exceeds VBR, shunting surge current to anode |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable, low-noise avalanche characteristics and long-term parameter stability under repeated surge stress |
| 400 W peak pulse power (10/1000 μs) | Validates capability to absorb common-mode surges per IEC 61000-4-5 without degradation |
| AEC-Q101 qualified (HE3 suffix) | Confirms reliability for automotive applications including engine control units, body electronics, and ADAS sensor interfaces |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ESD > 15 kV), improving system-level immunity |
| 175 °C maximum junction temperature | Enables placement near heat sources (e.g., power converters) without thermal derating penalties |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 24 V supply lines in vehicle ECUs from load-dump and jump-start transients. IC Role / Device Role / Timing Role: Unidirectional TVS clamping device placed between battery rail and downstream regulator input. Use Value: Clamps transients to ≤41.4 V, preventing damage to 36 V-rated LDOs and microcontrollers while maintaining AEC-Q101 compliance. | Use Scenario: Shielding analog outputs of pressure/temperature sensors in factory automation PLC modules. IC Role / Device Role / Timing Role: Standoff protector on 4–20 mA current loop output lines exposed to cable ESD and field wiring faults. Use Value: Limits induced voltage spikes to <42 V, preserving sensor accuracy and avoiding ADC saturation or op-amp latch-up. |
| MOSFET Gate Driver Protection | Consumer Power Adapter Input Stage |
Use Scenario: Safeguarding high-side N-channel MOSFET gates driven by isolated gate drivers in motor inverters. IC Role / Device Role / Timing Role: Fast-acting clamp between gate and source to suppress Miller-induced voltage overshoot during switching transitions.

IC Role / Device Role / Timing Role: Post-rectifier DC bus protector absorbing surge energy from mains-borne transients and capacitor discharge events. Use Value: Handles 400 W pulses without failure, maintaining 25.6 V standoff to avoid false triggering during normal 24 V DC operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ30A | Surface-mount SMB package (vs. axial DO-41); same VBR (28.5–31.5 V), slightly lower VC (48.4 V @ 8.3 A), 600 W PPPM | Requires PCB re-layout; better suited for high-density consumer electronics vs. through-hole industrial designs | Select SMBJ30A only if SMT assembly and space constraints justify redesign; P4KE30AHE3/54 retains mechanical robustness and thermal mass advantage in through-hole layouts |
| 1.5KE30A | Same DO-41 package but higher PPPM (1500 W); identical VBR/VWM/VC specs; no AEC-Q101 qualification | Lacks automotive qualification; used in non-automotive industrial power supplies where higher surge margin is needed | Choose 1.5KE30A for cost-sensitive, non-automotive applications requiring >400 W headroom; retain P4KE30AHE3/54 where AEC-Q101 traceability and controlled clamping are mandatory |
Compared with SMBJ30A and 1.5KE30A, the P4KE30AHE3/54 uniquely combines AEC-Q101 qualification, DO-41 mechanical reliability, and optimized 400 W clamping performance-making it the preferred choice for automotive and high-integrity industrial through-hole designs where qualification and proven surge endurance are non-negotiable.

FAQ
What is the breakdown voltage tolerance of P4KE30AHE3/54?
The P4KE30AHE3/54 has a specified breakdown voltage range of 28.5 V to 31.5 V at 1.0 mA test current (VBR min/max), representing ±5% tolerance around the nominal 30 V rating. This tight distribution ensures predictable clamping behavior across production batches and supports reliable design margining in safety-critical circuits.
Is P4KE30AHE3/54 suitable for bidirectional transient protection?
No, P4KE30AHE3/54 is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. For bidirectional protection, Vishay offers the P4KE30CA variant. Using P4KE30AHE3/54 in AC or symmetrical surge environments would result in forward conduction during negative half-cycles, potentially causing failure.
Does P4KE30AHE3/54 require a heatsink for 400 W pulse handling?
No external heatsink is required for single 10/1000 μs pulses, as the 400 W rating is defined under non-repetitive conditions. However, thermal management must account for RθJL = 66 °C/W and RθJA = 100 °C/W in PCB layout-maintaining adequate copper area and lead length (≤10 mm) to prevent junction temperature exceeding 175 °C during repetitive surges.
How does the HE3 suffix differ from E3 on P4KE30AHE3/54?
The HE3 suffix denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. In contrast, E3 indicates RoHS compliance only (commercial grade). P4KE30AHE3/54 is therefore certified for automotive under-hood use, whereas P4KE30AE3/54 is restricted to commercial applications.
What is the maximum reverse leakage current of P4KE30AHE3/54 at rated VWM?
At its 25.6 V stand-off voltage (VWM) and 25 °C ambient temperature, the P4KE30AHE3/54 exhibits a maximum reverse leakage current (ID) of 1.0 μA. This ultra-low leakage preserves efficiency in battery-backed systems and avoids false triggering in high-impedance sensing nodes.
