Product details
Overview
P4KE62A from Taiwan Semiconductor is a unidirectional 400W transient voltage suppressor (TVS) diode designed for overvoltage protection in DC power rails and signal lines. It features a 62V nominal breakdown voltage, 53.0V working stand-off voltage, 85V maximum clamping voltage at 5.0A peak pulse current, and operates across –55°C to +175°C junction temperature range - deployed in automotive power supply inputs and industrial sensor interfaces.
For engineers reviewing the P4KE62A datasheet, P4KE62A pinout, P4KE62A application, or P4KE62A equivalent, key selection criteria include clamping performance under 10/1000μs surge, low leakage (<1μA @ 53V), AEC-Q101 qualification status, DO-41 package compatibility, and unidirectional polarity marking for correct PCB orientation.
Technical Context
The P4KE62A implements a silicon avalanche diode structure optimized for fast transient suppression with sub-nanosecond response (<1.0ps from 0V to VBR). Its unidirectional configuration enables asymmetric conduction - forward-biased during normal operation and reverse-avalanche clamping during overvoltage events - ensuring minimal interference with system DC biasing.
Rated for 400W peak pulse power at 10/1000μs waveform and 1W steady-state dissipation at 75°C lead temperature, the device uses a DO-204AL (DO-41) package with pure tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance standards.

Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: 12V battery rail in engine control units exposed to load dump (ISO 7637-2 Pulse 5a) and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery input and LDO regulator input to clamp transients above 53V.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60A | Surface-mount SMB package; 60V VWM, 87V VC @ 4.6A; same 400W rating but lower IPPM | Requires PCB re-layout for SMT; better high-frequency impedance due to lower parasitic inductance | Select when board space is constrained and automated assembly is preferred over through-hole mounting |
| 1.5KE62A | Same DO-41 package; 62V nominal; 400W rating; slightly higher VC = 100V @ 4.0A; no AEC-Q101 variant available | Compatible footprint and polarity; higher clamping voltage reduces margin for 75V-rated components | Select only if AEC-Q101 qualification is not required and clamping voltage margin permits 100V peak |
Compared with SMBJ60A and 1.5KE62A, the P4KE62A offers superior thermal derating stability in through-hole designs, tighter VBR tolerance (±5% vs ±10%), and direct AEC-Q101 qualification path - making it optimal for automotive and high-reliability industrial deployments where mechanical robustness and long-term surge endurance are prioritized.

FAQ
What is the maximum clamping voltage of the P4KE62A under rated surge conditions?
The P4KE62A exhibits a maximum clamping voltage (VC) of 85 V when subjected to its rated 5.0 A peak pulse current (IPPM) under the standard 10/1000μs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during a full 400W transient event. The P4KE62A's clamping ratio (VC/VBR) is approximately 1.36, confirming tight voltage control relative to its 58.9–65.1 V breakdown range.
Is the P4KE62A suitable for bidirectional transient protection?
No, the P4KE62A is a unidirectional TVS diode and is not rated for bidirectional operation. Its electrical characteristics - including breakdown voltage, clamping behavior, and polarity marking - apply only in the reverse direction (cathode positive). For bidirectional protection, select the P4KE62CA variant, which provides symmetrical clamping in both polarities and uses a center-tap or dual-diode configuration. Using P4KE62A in AC or bipolar signal paths risks forward conduction failure or inadequate clamping.
Does the P4KE62A meet automotive qualification standards?
The base P4KE62A is not AEC-Q101 qualified; however, the P4KE62AH variant - identical in all electrical and mechanical specifications except for added automotive reliability testing - is fully AEC-Q101 qualified. The "H" suffix denotes qualification per stress tests including HTOL, TC, UHAST, and bond wire pull. For automotive applications requiring certified reliability, specify P4KE62AH; the P4KE62A remains suitable for industrial and commercial systems where AEC-Q101 is not mandated.
What is the reverse leakage current specification for the P4KE62A at its working voltage?
The P4KE62A specifies a maximum reverse leakage current (IR) of less than 1 μA when biased at its working stand-off voltage (VWM) of 53.0 V. This ultra-low leakage is confirmed at TA = 25°C and ensures minimal power loss and signal integrity impact in high-impedance circuits such as sensor bias networks or precision reference rails. Leakage remains below 5 μA up to 80% of VWM, supporting stable operation across temperature extremes.
Can the P4KE62A be used in parallel for higher surge current handling?
Parallel connection of P4KE62A devices is not recommended due to mismatch in dynamic impedance and avalanche turn-on characteristics, which causes uneven current sharing and potential thermal runaway. Each P4KE62A is characterized for 5.0 A IPPM at 85 V clamping; stacking units does not linearly scale surge capacity. For higher current requirements, select a single higher-rated device (e.g., P4KE75A or SMAJ70A) or consult TSC's application notes on coordinated multi-stage protection architectures using pre-surge limiters.
