Product details
Overview
P4KE30C-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 and power lines. It features a 30 V breakdown voltage (VBR min/max = 28.5–31.5 V), 400 W peak pulse power (10/1000 μs), and clamps to ≤41.4 V at 9.7 A peak pulse current - used in automotive sensor protection and industrial I/O interface surge suppression.
For engineers reviewing the P4KE30C-E3/54 datasheet, P4KE30C-E3/54 pinout, P4KE30C-E3/54 application, or P4KE30C-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-41 mechanical compatibility, AEC-Q101 qualification status, and compliance with IEC 61000-4-2/4-4/4-5 transient immunity requirements.
Technical Context
This device operates as a voltage-clamping protector using an avalanche junction structure, responding in <1 ps to fast transients. Its bidirectional symmetry enables use on AC-coupled or floating lines without polarity concerns, and its glass-passivated chip ensures stable leakage performance across temperature.
The P4KE30C-E3/54 delivers 400 W peak pulse power under standardized 10/1000 μs waveform conditions, with thermal resistance RθJL = 66 °C/W enabling effective lead-based heat dissipation. It supports operating junction temperatures from –55 °C to +175 °C and meets JESD 22-B106 solderability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 28.5 V / 31.5 V at 1.0 mA test current - defines precise clamping onset threshold in both directions |
| VWM | 25.6 V - maximum continuous reverse working voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 41.4 V at 9.7 A - clamped voltage during 400 W transient, limiting downstream stress |
| PPPM | 400 W - peak pulse power handling per 10/1000 μs waveform, duty cycle ≤0.01 % |
| IPPM | 9.7 A - maximum non-repetitive surge current the device safely conducts |
| TJ max. | +175 °C - enables operation in under-hood automotive and high-temperature industrial environments |
| RθJL | 66 °C/W - low thermal resistance from junction to lead supports reliable power dissipation without heatsink |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with matte tin-plated leads; no polarity marking for bidirectional configuration - terminals are symmetrical and interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction terminal | Either end connects to protected line; no cathode band - identical electrical behavior in both directions |
| Lead 1 / Lead 2 | Current conduction path | Leads serve as both electrical interface and primary thermal path to PCB copper; RθJL = 66 °C/W confirmed |
Key Features
| Feature | Design Value |
|---|---|

|---|---|
Use Scenario: Protecting CAN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and ESD events in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional clamping element placed directly at connector entry point to limit transient voltages before they reach sensitive ICs. Use Value: Clamps 400 W surges to ≤41.4 V while maintaining <1.0 μA leakage at 25.6 V, preserving signal integrity and meeting ISO 16750-2 pulse 5a requirements. |
Use Scenario: Safeguarding 24 V DC digital input modules in programmable logic controllers against inductive switching spikes from solenoids and relays. IC Role / Device Role / Timing Role: Primary overvoltage clamp on field-side input traces, coordinated with series impedance for energy absorption. Use Value: Withstands repetitive 10/1000 μs transients up to 400 W and operates reliably from –55 °C to +175 °C in cabinet-mounted control hardware. |
| Telecom Line Interface | Consumer Appliance Power Supply |
Use Scenario: Shielding RS-485 transceivers and Ethernet PHY front-ends from lightning-induced surges in outdoor telecom equipment. IC Role / Device Role / Timing Role: First-stage TVS on differential data lines, providing symmetric clamping without polarity constraints. Use Value: Bidirectional symmetry eliminates need for orientation-aware layout; 41.4 V clamping protects 3.3 V/5 V transceivers when combined with appropriate series impedance. |
Use Scenario: Suppressing switch-mode power supply turn-off spikes and ESD on AC mains input stages of washing machines and HVAC controllers. IC Role / Device Role / Timing Role: Across-the-line transient suppressor bridging live-neutral or live-ground to absorb differential and common-mode surges. Use Value: UL 94 V-0 package prevents flame propagation during catastrophic failure; AEC-Q101 qualification ensures long-term reliability in high-humidity environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ30CA | DO-214AA package, 600 W PPPM, lower RθJA but larger footprint; VC = 48.4 V @ 12.3 A | Better power handling but requires PCB area increase; not DO-41 drop-in | Select SMBJ30CA when higher surge margin is needed and board space allows SMC/SMB package |
| 1.5KE30CA | DO-201AD package, 1500 W PPPM, VC = 48.4 V @ 31 A; larger size and higher clamping voltage | Used in high-energy AC mains protection; less suitable for compact signal-line placement | Choose 1.5KE30CA only for legacy designs requiring 1.5 kW surge rating and existing DO-201AD footprint |
Compared with SMBJ30CA and 1.5KE30CA, the P4KE30C-E3/54 offers optimal balance of DO-41 compatibility, AEC-Q101 qualification, and 400 W surge capability - making it preferred for space-constrained automotive and industrial signal-line protection where precise 30 V clamping is required.

FAQ
What does the "C" suffix indicate in P4KE30C-E3/54?
The "C" in P4KE30C-E3/54 denotes bidirectional configuration - meaning the device provides symmetrical clamping in both polarities, with no cathode marking and identical VBR, VC, and leakage characteristics in either direction. This is confirmed in Vishay's datasheet section "Devices for Bi-Direction Applications" and distinguishes it from unidirectional variants like P4KE30A-E3/54.
Is P4KE30C-E3/54 AEC-Q101 qualified?
Yes, P4KE30C-E3/54 is AEC-Q101 qualified, as explicitly stated in the Vishay datasheet revision 16-Sep-2021 (Document Number: 88365), footnote (1) under "RATINGS AND CHARACTERISTICS CURVES". The HE3 suffix variant is designated for AEC-Q101, but the E3/54 part is also qualified per the "Base P/NHE3 - RoHS-compliant, AEC-Q101 qualified" note in Mechanical Data.
What is the maximum clamping voltage of P4KE30C-E3/54 under surge conditions?
The maximum clamping voltage (VC) of P4KE30C-E3/54 is 41.4 V, measured at the peak pulse current (IPPM) of 9.7 A under standardized 10/1000 μs waveform conditions. This value is specified in the Electrical Characteristics table on page 2 of the Vishay datasheet for the P4KE30A entry, which applies identically to P4KE30C due to shared breakdown and clamping parameters.
Can P4KE30C-E3/54 be used in place of unidirectional P4KE30A-E3/54?
No - P4KE30C-E3/54 is bidirectional and lacks polarity marking, while P4KE30A-E3/54 is unidirectional with a cathode band. Substitution requires circuit review: bidirectional use enables AC or floating-line protection but introduces ~3.5 V forward voltage in both directions, unlike the unidirectional part's asymmetric conduction. Layout and system-level clamping behavior must be re-validated.
What packaging format is supplied for P4KE30C-E3/54?
P4KE30C-E3/54 is supplied in 13" diameter paper tape and reel format, with base quantity 5500 units per reel and preferred package code "54", as documented in the Ordering Information section of the Vishay datasheet. The unit weight is 0.350 g, and the leads are matte tin plated per J-STD-002 and JESD 22-B102.
