Product details
Overview
P6KE62 from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a nominal breakdown voltage of 62 V, clamps transients to ≤89.0 V at 7.0 A peak surge current, and delivers fast response (<1.0 ps from 0 V to VBR), with stand-off voltage of 50.2 V and leakage <1 μA at rated VWM. It is used in automotive body control modules to protect CAN transceiver inputs against load dump and ISO 7637-2 pulses.
For engineers reviewing the P6KE62 datasheet, P6KE62 pinout, P6KE62 application, or P6KE62 equivalent, key selection criteria include its DO-204AC (DO-15) axial package, unidirectional polarity, 600W 10/1000μs surge rating, and suitability for industrial power supply input stage protection, telecom line interface ESD hardening, and automotive sub-system surge immunity per ISO 16750-2.
Technical Context
The P6KE62 operates as a silicon avalanche diode optimized for clamping high-energy transients while maintaining low dynamic impedance. Its unidirectional configuration enables integration into DC-biased circuits where reverse conduction must be blocked-e.g., positive-rail protection downstream of rectifiers or regulators.
It complies with ANSI/IEEE C62.35 for surge testing and supports AEC-Q101 qualification when ordered with "H" suffix (P6KE62H). Junction temperature range is –55°C to +175°C, and thermal derating begins above 25°C ambient per Fig.2, enabling reliable operation in under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W at 10/1000 μs waveform - sustains single-event surges up to IPP = 7.0 A without failure |
| Breakdown Voltage VBR | 55.8–68.2 V at 1 mA test current - defines precise avalanche onset threshold for predictable clamping |
| Clamping Voltage VC | ≤89.0 V at IPP = 7.0 A - limits protected circuit voltage during surge, ensuring downstream ICs stay within absolute max ratings |
| Stand-off Voltage VWM | 50.2 V - maximum continuous DC or RMS voltage the device blocks without significant leakage (<1 μA) |
| Junction Temperature Range | –55°C to +175°C - supports operation in harsh environments including engine compartments and industrial motor drives |
| Package | DO-204AC (DO-15) - axial-leaded, through-hole mountable package with UL 94V-0 molding compound and tin-plated leads |
| Response Time | <1.0 ps (0 V to VBR) - enables suppression before transient energy couples into sensitive analog or digital circuitry |
Pinout & Package
DO-204AC (DO-15) axial package with cathode band marking; leads are pure tin-plated and solderable per J-STD-002. Polarity is unidirectional: anode (unmarked end) and cathode (banded end).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | DC return / ground reference terminal | Connected to system ground or low-side rail; carries surge current back to source during clamping |
| Cathode | Protected line input terminal | Connected to line being protected (e.g., +12 V rail); avalanche conduction occurs from cathode to anode during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| Avalanche clamping with low dynamic impedance | Ensures stable VC across varying surge currents - critical for consistent protection margin in variable-load systems |
| UL 94V-0 flammability rated epoxy | Prevents flame propagation during catastrophic surge events - required for automotive and industrial safety compliance |
| AEC-Q101 qualified option (P6KE62H) | Validated for automotive electronics per stress test requirements - enables use in ASIL-B relevant subsystems without requalification |
| JESD201 Class 2 whisker resistance | Eliminates tin whisker growth risk over lifetime - ensures long-term reliability in high-reliability embedded applications |
| Halogen-free per IEC 61249-2-21 | Meets RoHS and environmental compliance mandates for global OEM supply chains - no brominated flame retardants |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse P6KE62A | Higher VBR range (58.9–65.1 V), tighter tolerance; same DO-15 package and 600 W rating | Slightly higher clamping voltage (85.0 V vs. 89.0 V) allows marginally lower stress on downstream components | Select P6KE62A when tighter VBR distribution and lower VC are prioritized over cost sensitivity |
| ON Semiconductor 1.5KE62A | Same VBR/VC specs but rated for 1500 W (10/1000 μs); larger DO-201AD package | Higher surge capacity suits infrequent but extreme events (e.g., utility grid switching); requires PCB layout change | Choose 1.5KE62A only if system-level testing confirms need for >600 W capability and board space permits larger footprint |
Compared with P6KE62, P6KE62A offers improved VBR consistency and lower clamping, while 1.5KE62A trades package compatibility for higher surge headroom-making P6KE62 the optimal balance of size, performance, and cost for standard 600 W protection needs.

FAQ
What is the maximum clamping voltage of the P6KE62 under surge conditions?
The P6KE62 clamps to a maximum of 89.0 V when subjected to its rated 7.0 A peak pulse current (IPP) using the 10/1000 μs waveform. This value is measured at TA = 25°C and represents the upper limit of voltage seen by downstream circuitry during a defined surge event. The actual clamping voltage of the P6KE62 may decrease slightly at lower temperatures and increase marginally at elevated junction temperatures, per its temperature coefficient of VBR (0.104 %/°C).
Is the P6KE62 suitable for bidirectional transient protection?
No, the P6KE62 is a unidirectional TVS diode intended only for DC-biased applications where reverse conduction must be blocked. For bidirectional protection (e.g., AC lines or differential data buses), the P6KE62CA variant is specified - it has symmetrical breakdown in both directions and identical clamping performance. Using the P6KE62 in a bidirectional configuration risks forward conduction and failure during negative transients.
Does the P6KE62 meet automotive qualification standards?
The base P6KE62 is not AEC-Q101 qualified; however, the P6KE62H variant is fully AEC-Q101 qualified per stress test requirements for automotive electronics. The "H" suffix denotes qualification including temperature cycling, humidity bias HAST, and accelerated life testing. Engineers specifying the P6KE62 for automotive use must select P6KE62H to ensure compliance with OEM reliability mandates.
What is the leakage current specification for the P6KE62 at its stand-off voltage?
At its maximum stand-off voltage of 50.2 V, the P6KE62 exhibits a maximum reverse leakage current (ID) of 1 μA at TA = 25°C. This ultra-low leakage ensures minimal power loss in always-on circuits and prevents unintended biasing of downstream high-impedance nodes. Leakage remains below 5 μA up to 75°C ambient, supporting reliable operation in thermally demanding enclosures.
Can the P6KE62 be used in parallel to increase surge current handling?
No - the P6KE62 should not be paralleled due to mismatch in VBR (55.8–68.2 V) and dynamic impedance, which causes uneven current sharing and potential thermal runaway. To handle higher surge currents, select a higher-power TVS (e.g., 1.5KE62A) or implement staged protection with upstream current-limiting resistors or PTCs. Derating curves in the P6KE62 datasheet confirm single-device operation only.
