Product details
Overview
P6KE30A-E3/54 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-15 package, designed for primary overvoltage protection of sensitive electronics. It features 30 V nominal breakdown voltage (VBR = 28.5–31.5 V at 1.0 mA), 41.4 V maximum clamping voltage at 14.5 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - used to safeguard MOSFETs, ICs, and sensor signal lines against inductive switching transients in industrial and automotive systems.
For engineers reviewing the P6KE30A-E3/54 datasheet, P6KE30A-E3/54 pinout, P6KE30A-E3/54 application, or P6KE30A-E3/54 equivalent, this device delivers verified bidirectional-capable surge suppression performance, RoHS-compliant commercial-grade construction, and AEC-Q101 qualification (via HE3 variant), supporting design-in for ESD and lightning-induced transient immunity in DC power rails and low-speed data interfaces.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: it remains high-impedance below 25.6 V stand-off voltage (VWM) and rapidly avalanches above 28.5 V to clamp transients within 41.4 V at 14.5 A. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance.
Designed for 10/1000 μs surge waveforms at 0.01% duty cycle, the P6KE30A-E3/54 sustains 600 W peak pulse power and handles up to 100 A non-repetitive forward surge current (8.3 ms half-sine). Thermal resistance is 20 °C/W junction-to-lead, enabling reliable operation up to +175 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 28.5 V / 31.5 V at 1.0 mA - defines precise avalanche initiation threshold for repeatable clamping behavior |
| VWM | 25.6 V - maximum continuous reverse working voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 41.4 V at 14.5 A - clamping voltage under full 600 W surge, limiting downstream component stress |
| PPPM | 600 W - peak pulse power handling with 10/1000 μs waveform, critical for IEC 61000-4-5 Level 4 compliance |
| IPPM | 14.5 A - maximum non-repetitive peak pulse current supported without degradation |
| TJ max. | +175 °C - enables use in under-hood automotive and high-temperature industrial environments |
| RθJL | 20 °C/W - low thermal resistance allows efficient heat transfer to PCB copper or heatsinked leads |
Pinout & Package

|---|---|
|
Use Scenario: Protection of gate drivers and feedback sensors in 24 V DC motor drives exposed to inductive kickback from relay and solenoid switching. IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed across power input or signal lines to clamp transients <100 ns after onset. Use Value: Limits voltage excursions to ≤41.4 V during 14.5 A surges, preventing latch-up or oxide rupture in 3.3 V/5 V interface ICs. |
Use Scenario: Overvoltage suppression on LIN bus lines and door module power inputs subjected to load dump and jump-start conditions. IC Role / Device Role / Timing Role: Standby-mode protector with 25.6 V VWM, activated only during >28.5 V transients to avoid interference with normal signaling. Use Value: Enables compliance with ISO 7637-2 Pulse 1/2a/5a while maintaining low leakage (<1 μA) during 12 V battery operation. |
| Consumer Power Adapters | Telecom DC Feeds |
|
Use Scenario: Secondary-side surge protection in AC/DC adapters for USB-C PD and smart home hubs, guarding against capacitor discharge events. IC Role / Device Role / Timing Role: Low-cost, high-energy clamping element placed between output rail and ground, sized for 600 W peak dissipation. Use Value: Absorbs 10/1000 μs surges without failure, eliminating need for additional series impedance or active crowbar circuits. |
Use Scenario: Primary overvoltage guard on -48 V telecom power distribution boards where lightning-induced surges exceed 1 kV. IC Role / Device Role / Timing Role: First-line shunt suppressor upstream of DC/DC converters and PMICs, rated for repetitive 0.01% duty cycle operation. Use Value: Maintains 41.4 V clamping level even after multiple surges, preserving integrity of downstream 5 V and 3.3 V regulation stages. |
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 | DO-214AA package, 30 V VBR, 48.4 V VC @ 12.3 A, same 600 W rating but lower IPPM | Surface-mount alternative requiring PCB redesign; higher clamping voltage reduces margin for 3.3 V ICs | Select when board space constraints prohibit axial DO-15 placement and thermal mass is sufficient for SMB footprint |
| 1.5KE30A | Same DO-15 package, 30 V VBR, but 46.3 V VC @ 12.9 A and 1500 W rating - larger die, higher capacitance | Higher energy handling suits infrequent high-energy events; slower response due to larger junction area | Choose for legacy designs requiring higher single-pulse robustness where 1500 W rating justifies increased cost and size |
Compared with SMBJ30A and 1.5KE30A, the P6KE30A-E3/54 offers optimal balance of clamping performance (41.4 V), compact axial form factor, and commercial-grade cost-making it ideal for high-volume industrial and automotive applications where predictable 600 W surge absorption and DO-15 through-hole assembly are required.

FAQ
What is the breakdown voltage tolerance for P6KE30A-E3/54?
The P6KE30A-E3/54 has a specified breakdown voltage range of 28.5 V to 31.5 V at 1.0 mA test current, representing ±5% tolerance around the nominal 30 V rating. This tight VBR window ensures consistent clamping behavior across production lots and supports reliable system-level surge margining in designs using the P6KE30A-E3/54.
Is P6KE30A-E3/54 suitable for automotive applications?
The P6KE30A-E3/54 is RoHS-compliant and commercial-grade; however, its AEC-Q101 qualified counterpart is P6KE30AHE3/54 (HE3 suffix). For automotive body electronics requiring qualification, the HE3 variant must be selected. The P6KE30A-E3/54 itself meets all electrical and mechanical specs but lacks formal AEC-Q101 certification - use only in non-safety-critical, non-qualified automotive subsystems.
How does the clamping voltage of P6KE30A-E3/54 compare to its breakdown voltage?
The P6KE30A-E3/54 clamps to a maximum of 41.4 V at 14.5 A peak pulse current, yielding a clamping ratio (VC/VBR) of approximately 1.42. This low ratio reflects efficient avalanche conduction and minimal voltage overshoot, directly protecting downstream 3.3 V or 5 V ICs when the P6KE30A-E3/54 is placed in parallel with their power inputs.
What is the maximum operating temperature for P6KE30A-E3/54?
The P6KE30A-E3/54 has a maximum junction temperature (TJ) rating of +175 °C, allowing operation in high-ambient environments such as engine compartments or enclosed industrial enclosures. Derating begins above 25 °C ambient per Figure 2 in the datasheet, and thermal resistance junction-to-lead is 20 °C/W - critical for calculating safe power dissipation when using the P6KE30A-E3/54 in thermally constrained layouts.
Can P6KE30A-E3/54 be used in bidirectional configurations?
No - the P6KE30A-E3/54 is a unidirectional TVS diode, identified by the "A" suffix and cathode band marking. Bidirectional variants use the "CA" suffix (e.g., P6KE30CA). Using the P6KE30A-E3/54 in AC or bipolar signal paths would result in forward conduction during negative half-cycles; for bidirectional protection, the P6KE30CA or equivalent must be selected instead of the P6KE30A-E3/54.
