Product details
Overview
P6KE62A from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-side overvoltage protection in power supply inputs, DC bus lines, and automotive electronics. It features a nominal breakdown voltage of 62 V, clamping voltage of 85.0 V at 7.4 A peak surge current, stand-off voltage of 53.0 V, and low dynamic impedance for effective ESD and lightning surge suppression.
For engineers reviewing the P6KE62A datasheet, P6KE62A pinout, P6KE62A application, or P6KE62A equivalent, this device is selected for robust transient immunity in 48 V industrial power rails, automotive body control modules, and PoE-powered equipment where fast response (<1 ps), low leakage (<1 µA @ 53 V), and AEC-Q101 qualification are critical.
Technical Context
The P6KE62A operates as a silicon avalanche diode with unidirectional polarity, activated when reverse voltage exceeds its 58.9–65.1 V breakdown range at 1 mA test current. Its junction capacitance is not specified in the provided documentation, but its fast response time (<1.0 ps from 0 V to VBR) enables suppression of ESD events per IEC 61000-4-2 and electrical fast transients per IEC 61000-4-4.
Thermally rated for continuous operation from –55 °C to +175 °C, it dissipates up to 5 W at 75 °C ambient when mounted on 5 × 5 mm copper pads. The device complies with UL 94V-0 flammability standards and meets JESD 201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V at 1 mA - defines reliable turn-on threshold under surge conditions |
| VWM | 53.0 V - maximum continuous reverse operating voltage before leakage rises significantly |
| VC @ IPP | 85.0 V at 7.4 A - clamping voltage during 10/1000 µs surge, limiting downstream stress |
| PPK | 600 W - peak pulse power handling capability for standardized lightning/surge waveforms |
| IR @ VWM | <1 µA - ultra-low reverse leakage ensures minimal standby power loss in high-impedance circuits |
| TJ max | +175 °C - high junction temperature rating supports under-hood automotive and industrial environments |

Pinout & Package
DO-204AC (DO-15) axial-leaded package with cathode band marking; leads are pure tin-plated and solderable per J-STD-002. Polarity is unidirectional: anode (unmarked end), cathode (banded end).

|---|---|---|
| Anode | Ground reference terminal | Connected to system ground or low-side return path; conducts forward surge current during clamping |
| Cathode | Protected line input | Connected to protected node (e.g., 48 V rail); reverse-biased during normal operation, avalanches during overvoltage |

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 | Lower peak power (600 W same), but SMB package (surface-mount); VBR = 66.7–73.7 V, VC = 96.8 V @ 6.2 A | Requires PCB rework for SMT layout; better suited for space-constrained designs with automated assembly | Select SMBJ60A only if board real estate is limited and thermal management via copper pour is feasible. |
| 1.5KE62A | Same DO-15 package and 62 V rating, but higher PPK = 1500 W; VC = 100 V @ 15 A; larger physical size | Over-spec'd for 600 W needs; used where multi-event surge endurance or legacy design continuity is required | Choose 1.5KE62A only when system-level testing demands >1000 W margin or existing footprint accommodates larger body. |
Compared with SMBJ60A and 1.5KE62A, the P6KE62A offers optimal balance of axial-lead manufacturability, 600 W surge capacity, and tight 58.9–65.1 V breakdown tolerance-making it ideal for cost-sensitive, high-volume industrial and automotive power protection where DO-15 mounting and AEC-Q101 compliance are prioritized.

FAQ
What is the breakdown voltage range of the P6KE62A?
The P6KE62A has a guaranteed breakdown voltage range of 58.9 V to 65.1 V at 1 mA test current, measured per ANSI/IEEE C62.35. This tight VBR window ensures predictable turn-on behavior in overvoltage protection circuits and supports precise coordination with downstream overvoltage lockout thresholds. The P6KE62A maintains this specification across its full operating temperature range.
Is the P6KE62A suitable for automotive applications?
Yes-the P6KE62A is part of the AEC-Q101-qualified P6KE series (specifically the P6KE62AH variant). While the base P6KE62A is not automatically qualified, its construction, materials, and test data align with AEC-Q101 requirements. For certified automotive use, specify P6KE62AH; both share identical electrical parameters including 85.0 V clamping voltage and 53.0 V stand-off voltage.
What is the maximum clamping voltage of the P6KE62A during a surge event?
The P6KE62A clamps to a maximum of 85.0 V at 7.4 A peak pulse current (IPP) under the standard 10/1000 µs waveform. This value is measured at TA = 25 °C and represents worst-case voltage seen by downstream circuitry during surge conduction. The P6KE62A achieves this with low dynamic impedance, minimizing energy dissipation in protected ICs.
How does the P6KE62A compare to the P6KE62 (non-A) version?
The P6KE62A offers tighter breakdown voltage tolerance (58.9–65.1 V) versus P6KE62 (55.8–68.2 V), resulting in more consistent clamping behavior and improved system-level surge margin. Both share identical package (DO-15), power rating (600 W), and thermal specs. The P6KE62A is the preferred choice for designs requiring tighter VBR control without changing layout or bill of materials.
What packaging options are available for the P6KE62A?
The P6KE62A is supplied in DO-204AC (DO-15) axial-leaded package, available in tape-and-reel (3,500 pcs) and ammo box (1,500 pcs) formats. Lead finish is pure tin, compliant with J-STD-002 for solderability. No surface-mount variants exist for the P6KE62A; alternatives like SMBJ60A require different footprints and thermal design considerations.
