Product details
Overview
P6KE62C from Taiwan Semiconductor is a bidirectional 600W transient voltage suppressor (TVS) diode designed for robust 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 (<5.0 ns) with low dynamic impedance. It is used in automotive body electronics, industrial I/O modules, and AC/DC adapter input stages to protect downstream ICs from EFT and lightning-induced surges.
For engineers reviewing the P6KE62C datasheet, P6KE62C pinout, P6KE62C application, or P6KE62C equivalent, key selection criteria include its bidirectional configuration, DO-204AC (DO-15) package compatibility, 50.2 V standoff voltage, and UL 94V-0 rated molding compound - all critical for board-level surge immunity compliance in harsh environments.
Technical Context
The P6KE62C operates as a silicon avalanche diode with symmetrical bidirectional clamping behavior, enabling protection against both positive and negative polarity transients without external polarity management. Its junction capacitance is not specified in the provided documentation, and it exhibits a temperature coefficient of VBR at 0.104 %/°C.
It complies with ANSI/IEEE C62.35 for transient suppression and meets AEC-Q101 qualification when ordered with the "H" suffix (e.g., P6KE62CH), though the base P6KE62C variant is not explicitly marked as AEC-Q101 qualified per the ordering table.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 55.8 V / 68.2 V - Ensures reliable avalanche conduction onset across manufacturing tolerance and temperature range |
| VWM | 50.2 V - Maximum continuous reverse operating voltage before leakage exceeds 1 μA |
| VC @ IPP | 89.0 V @ 7.0 A - Clamped voltage during 10/1000 μs surge, defining maximum stress on protected circuitry |
| PPK | 600 W - Peak pulse power handling capability under standardized 10/1000 μs waveform |
| IR @ VWM | <1 μA - Low leakage ensures minimal standby power loss and signal integrity in high-impedance nodes |

| Package | DO-204AC (DO-15) - Industry-standard axial leaded package with 0.400 g mass and tin-plated leads per J-STD-002 |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, molded epoxy case with cathode band marking for unidirectional variants; P6KE62C is bidirectional and lacks polarity marking - terminals are functionally symmetric.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional avalanche junction | Either terminal accepts positive or negative transient energy - no PCB polarity orientation required |
Key Features
| Feature | Design Value |
|---|---|
| UL Recognition | UL file #E-326243 - Validates safety compliance for end-equipment certification (e.g., IEC 62368-1) |
| Flammability Rating | UL 94V-0 molding compound - Prevents flame propagation during fault conditions |
| RoHS & Halogen-Free | Compliant per RoHS Directive and IEC 61249-2-21 - Supports environmental compliance and soldering reliability |
| Whisker Resistance | Meets JESD201 Class 2 - Eliminates tin whisker risk in long-life, high-reliability applications |
| Surge Response Time | <5.0 ns (bidirectional) - Limits voltage overshoot before clamping engages |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Card |
|---|---|
Use Scenario: Protects microcontroller GPIO and CAN transceiver power rails from load dump and inductive switching spikes in 12 V vehicle systems. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed directly at connector entry point before EMI filter and LDO. Use Value: Withstands 600 W surges and clamps to ≤89.0 V, preventing latch-up or permanent damage to 5 V/3.3 V logic interfaces. |
Use Scenario: Shields 24 V DC digital input optocoupler circuits from field-wiring induced transients in factory automation cabinets. IC Role / Device Role / Timing Role: First-line transient suppressor mounted adjacent to screw-terminal block, upstream of series current-limiting resistor. Use Value: 50.2 V standoff allows stable operation under 24 V ±10 % supply variation while suppressing 1 kV/50 Ω EFT bursts per IEC 61000-4-4. |
| AC/DC Adapter Input Stage | Smart Lighting Driver EMI Filter Node |
Use Scenario: Guards bridge rectifier output and bulk capacitor from line-side surges (e.g., lightning-induced ring waves) in Class II power supplies. IC Role / Device Role / Timing Role: Parallel-connected TVS across DC bus, sized to absorb residual energy after MOV clamping. Use Value: 600 W rating and 89.0 V clamping complement MOV-based primary protection, reducing stress on secondary-side controllers. |
Use Scenario: Suppresses fast-rising transients coupled onto LED driver control lines from nearby switching MOSFETs or relay coils. IC Role / Device Role / Timing Role: Localized protection at dimming interface (e.g., 0–10 V or DALI) pins of LED driver IC. Use Value: Sub-5 ns response ensures clamping occurs before transient propagates into sensitive analog comparators or UART receivers. |
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 SMAJ60CA | Same DO-214AC (SMA) package; 600 W rating; VBR = 66.7–73.7 V; VC = 96.8 V @ 6.2 A | Higher clamping voltage (+7.8 V) and lower surge current (6.2 A vs. 7.0 A); requires PCB footprint change | Select when SMA package preferred for automated assembly or space-constrained layouts |
| ON Semiconductor 1.5KE62CA | Same DO-15 package; 1500 W rating; VBR = 55.8–68.2 V; VC = 85.0 V @ 17.6 A | Higher power rating enables longer surge duration handling but larger thermal mass and higher cost | Select when system-level testing requires margin beyond IEC 61000-4-5 Level 4 (4 kV) |
Compared with P6KE62C, SMAJ60CA offers surface-mount convenience at the cost of higher clamping and footprint incompatibility, while 1.5KE62CA provides greater surge endurance in the same axial package but with increased bill-of-materials cost and thermal inertia.

FAQ
What is the polarity configuration of P6KE62C?
P6KE62C is a bidirectional TVS diode, meaning it provides symmetrical clamping for both positive and negative transients without requiring specific anode/cathode orientation on the PCB. Unlike unidirectional variants (e.g., P6KE62A), it has no cathode band marking and functions identically regardless of terminal connection direction. This simplifies layout and eliminates polarity-related assembly errors in P6KE62C implementations.
Does P6KE62C meet AEC-Q101 qualification?
P6KE62C itself is not AEC-Q101 qualified per the official ordering guide; only variants with the "H" suffix (e.g., P6KE62CH) carry AEC-Q101 certification. The base P6KE62C is intended for industrial and commercial applications where automotive-grade stress testing is not mandated. Engineers requiring AEC-Q101 compliance must specify P6KE62CH and verify qualification status via Taiwan Semiconductor's official documentation.
What is the maximum clamping voltage of P6KE62C under surge conditions?
The maximum clamping voltage (VC) of P6KE62C is 89.0 V at a peak pulse current (IPP) of 7.0 A, measured using the standard 10/1000 μs double-exponential waveform. This value defines the upper voltage limit imposed on protected circuitry during transient events and must be compared against the absolute maximum ratings of downstream components to ensure survivability.
Can P6KE62C replace P6KE62A in an existing design?
No - P6KE62C and P6KE62A are not interchangeable without validation. P6KE62A is unidirectional with a cathode band and optimized for single-polarity clamping, while P6KE62C is bidirectional with symmetrical characteristics. Swapping them may result in improper protection behavior, especially in DC-biased circuits where reverse conduction could cause unintended current paths or latch-up in P6KE62C.
What is the standoff voltage (VWM) of P6KE62C and why does it matter?
The standoff voltage (VWM) of P6KE62C is 50.2 V - the maximum continuous reverse voltage it can block without exceeding 1 μA leakage current. This parameter ensures the device remains non-conductive during normal operation, avoiding power loss or signal distortion. It must exceed the peak operating voltage of the protected line (e.g., 24 V DC systems require ≥27.6 V VWM, making P6KE62C suitable for 48 V nominal buses).
