Product details
Overview
P4KE62A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on DC power rails and signal lines. It features a 53.0 V stand-off voltage (VWM), 58.9–65.1 V breakdown voltage (VBR) at 1.0 mA test current, and clamps up to 85.0 V at 4.7 A peak pulse current under 10/1000 μs waveform - enabling robust protection of MOSFETs, ICs, and sensor interfaces in automotive and industrial systems.
For engineers reviewing the P4KE62A-E3/54 datasheet, P4KE62A-E3/54 pinout, P4KE62A-E3/54 application, or P4KE62A-E3/54 equivalent, key selection criteria include its 400 W peak pulse power rating, AEC-Q101 qualification, glass-passivated junction, low incremental surge resistance, and compatibility with J-STD-002 solderability standards.
Technical Context
The P4KE62A-E3/54 operates as a unidirectional avalanche diode, leveraging a glass-passivated silicon junction to achieve fast response (<1 ns) and stable clamping during ESD or inductive switching events. Its thermal resistance (RθJL = 66 °C/W) and 175 °C maximum junction temperature support reliable operation in high-temperature environments without active cooling.
Designed for single-pulse transient suppression, it complies with 10/1000 μs waveform standards per REA definitions and derates linearly above 25 °C ambient - maintaining 400 W capability only at TA ≤ 25 °C, dropping to ~240 W at 75 °C per Fig. 2. The color band denotes cathode polarity, confirming unidirectional conduction path.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 53.0 V - Maximum continuous reverse voltage before significant leakage; sets operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 58.9–65.1 V at 1.0 mA - Confirmed avalanche onset range; ensures predictable turn-on during overvoltage |
| VC (Clamping Voltage) | 85.0 V at IPPM = 4.7 A - Peak voltage seen by protected circuit during 10/1000 μs surge; defines worst-case stress |
| PPPM (Peak Pulse Power) | 400 W - Sustained energy absorption capability for short-duration transients; enables protection against IEC 61000-4-5 Level 3 surges |
| ID (Reverse Leakage) | 1.0 μA at VWM - Ultra-low leakage preserves system efficiency and battery life in always-on circuits |
| TJ max. | 175 °C - Enables deployment in under-hood automotive or industrial motor-control enclosures without derating penalties |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with matte tin-plated leads; 0.205" (5.2 mm) body diameter, 1.0" (25.4 mm) minimum lead length; RoHS-compliant, AEC-Q101 qualified (E3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in unidirectional clamp configuration |
| Cathode (banded end) | Avalanche clamping terminal | Connected to protected line (e.g., +12 V rail); conducts when reverse voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR over lifetime and immunity to humidity-induced parameter drift in harsh environments |
| 400 W peak pulse power (10/1000 μs) | Supports protection against ISO 7637-2 Pulse 1/2a/3a and IEC 61000-4-5 Combination Wave surges |
| AEC-Q101 qualification | Validated for automotive powertrain and chassis applications requiring zero defect reliability and extended temperature cycling |
| Low incremental surge resistance | Minimizes clamping voltage overshoot during fast-rising transients (e.g., relay coil flyback) |
| Solderable per J-STD-002/JESD 22-B102 | Guarantees consistent wetting and joint integrity in automated reflow and wave soldering processes |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Clamping |
|---|---|
Use Scenario: Protecting 12 V supply lines in engine control units (ECUs) from load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between battery rail and local regulator input. Use Value: Clamps transients to ≤85.0 V, preventing damage to downstream LDOs and microcontrollers rated for 40 V absolute maximum. |
Use Scenario: Shielding analog outputs of pressure sensors in factory automation PLC modules from ESD and cable discharge events. IC Role / Device Role / Timing Role: Standoff-connected TVS on 4–20 mA loop output line, referenced to signal ground. Use Value: Sub-1 ns response limits voltage excursion during 8 kV contact ESD (IEC 61000-4-2), preserving ADC accuracy and sensor calibration stability. |
| Consumer Device USB Port Protection | MOSFET Gate Driver Surge Suppression |
Use Scenario: Safeguarding USB VBUS lines in portable medical monitors against hot-plug induced transients. IC Role / Device Role / Timing Role: Unidirectional TVS mounted directly at USB connector, cathode to VBUS, anode to ground. Use Value: 1.0 μA leakage at 53.0 V prevents standby current drain while 400 W rating absorbs repeated 10/1000 μs surges from faulty chargers. |
Use Scenario: Preventing gate oxide rupture in high-side N-channel MOSFETs driven by PWM controllers in motor inverters. IC Role / Device Role / Timing Role: TVS across gate-source terminals to clamp Miller-induced spikes during switching transitions. Use Value: 85.0 V clamping voltage stays well below typical 100 V gate-source rating, eliminating risk of cumulative dielectric degradation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64A | DO-214AA package; 64 V VBR min, 100 W PPPM (lower power density) | Higher thermal resistance (RθJA ≈ 150 °C/W) limits use in high-ambient or high-duty-cycle scenarios | Select when board space is constrained and peak surge energy is ≤100 W; not drop-in due to different footprint and lower power rating |
| 1.5KE62A | Same DO-41 package; identical VBR/VWM/VC specs but 1500 W PPPM (higher surge capacity) | Higher IFSM (125 A vs. 40 A) supports stronger inductive kickback handling | Choose when protecting high-energy circuits like solenoid drivers; requires verifying PCB trace current rating for 125 A surge |
Compared with SMBJ64A, P4KE62A-E3/54 delivers 4× higher pulse power in the same legacy DO-41 footprint; versus 1.5KE62A, it trades surge capacity for tighter VBR tolerance and lower cost in moderate-energy applications.

FAQ
What is the clamping voltage of the P4KE62A-E3/54 under standard test conditions?
The P4KE62A-E3/54 has a maximum clamping voltage (VC) of 85.0 V when subjected to a 10/1000 μs waveform at 4.7 A peak pulse current. This value is measured per REA-defined transient standards and represents the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring downstream components remain within their absolute maximum ratings.
Is the P4KE62A-E3/54 suitable for automotive applications?
Yes, the P4KE62A-E3/54 is AEC-Q101 qualified and manufactured with glass-passivated junction technology, making it suitable for automotive powertrain and body electronics. Its 175 °C maximum junction temperature, low leakage (1.0 μA), and validated performance across temperature cycling align with requirements for engine control units and lighting modules where long-term reliability is mandatory.
How does the P4KE62A-E3/54 differ from bidirectional TVS diodes like P4KE62CA?
The P4KE62A-E3/54 is unidirectional and features a cathode band for polarity identification, while P4KE62CA is bidirectional with no marking and symmetrical clamping in both directions. The P4KE62A-E3/54 offers lower forward voltage (VF = 3.5 V) and is intended for DC rail protection; P4KE62CA suits AC-coupled or floating signal lines where polarity reversal may occur.
What is the thermal resistance of the P4KE62A-E3/54, and how does it affect layout design?
The P4KE62A-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 66 °C/W and junction-to-ambient (RθJA) of 100 °C/W with 10 mm lead length. This means PCB copper pour under the leads significantly improves power dissipation - for sustained 1.5 W operation, thermal relief must be minimized and heatsinking leads recommended to avoid exceeding 175 °C junction temperature.
Can the P4KE62A-E3/54 be used in parallel for higher surge current handling?
No, the P4KE62A-E3/54 should not be paralleled without external balancing resistors due to VBR mismatch (58.9–65.1 V range), which causes uneven current sharing and potential thermal runaway. For higher IPPM, select a single higher-rated device like 1.5KE62A or use a TVS array with matched characteristics - never assume inherent current-sharing capability in discrete TVS diodes.
