Product details
Overview
P6KE62CAH from Taiwan Semiconductor is a bidirectional 600W transient voltage suppressor (TVS) diode designed for robust overvoltage protection in automotive and industrial power rails. It features a nominal breakdown voltage of 62 V, clamps transients to ≤89.0 V at 7.0 A peak surge current, and delivers sub-5 ns response time with <1 μA reverse leakage above 53.0 V standoff voltage - deployed in DC power input stages of automotive ECUs and industrial PLCs.
For engineers reviewing the P6KE62CAH datasheet, P6KE62CAH pinout, P6KE62CAH application, or P6KE62CAH equivalent, key selection criteria include its AEC-Q101 qualification, DO-204AC (DO-15) package compatibility, bidirectional clamping symmetry, 175°C junction rating, and compliance with IEC 61000-4-4/5 EFT/surge immunity requirements.
Technical Context
The P6KE62CAH implements a silicon avalanche diode structure optimized for fast transient suppression in bidirectional signal and power lines. Its 10/1000 µs waveform surge rating of 600 W and clamping voltage of 89.0 V at 7.0 A define its energy-handling capability under standardized lightning-induced surges.
With a maximum temperature coefficient of VBR at 0.104 %/°C and guaranteed operation from −55°C to +175°C, it maintains stable clamping performance across automotive under-hood thermal environments. Its low dynamic impedance ensures minimal voltage overshoot during fast-rising transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 55.8 V / 68.2 V at 1 mA test current - defines reliable avalanche initiation window under varying production tolerances |
| VWM | 53.0 V - maximum continuous reverse operating voltage before significant leakage begins |
| IPP | 7.0 A at 10/1000 µs waveform - peak surge current it safely clamps without failure |
| VC @ IPP | 89.0 V - clamped voltage seen by protected circuit during full-rated surge event |
| PPK | 600 W - non-repetitive peak pulse power dissipation capability per JEDEC standard |
| TJMAX | +175°C - enables placement near high-temperature components like power MOSFETs or engine controllers |
| Response Time | <5.0 ns - ensures suppression activation before transient energy damages downstream ICs |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case with UL 94V-0 flammability rating and pure tin-plated leads compliant with J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Current entry terminal in forward bias; cathode reference in reverse clamp mode | Bidirectional operation means either terminal serves as anode/cathode depending on transient polarity - no fixed polarity marking required |
| Cathode (banded end) | Reference terminal for unidirectional variants; functional symmetry point in bidirectional use | Band denotes cathode for unidirectional versions; for P6KE62CAH, band identifies terminal used as reference in layout but does not restrict conduction direction |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per stress test plan |
| Bidirectional clamping | Identical VBR, VC, and IPP specs in both directions - eliminates need for polarity-aware placement in AC-coupled or floating rails |
| Low dynamic impedance | Enables tight clamping margin (VC − VBR ≈ 20.8 V) - reduces stress on downstream TVS or IC ESD structures |
| Halogen-free & RoHS | Complies with IEC 61249-2-21 and EU RoHS Directive - supports green manufacturing and end-of-life recycling requirements |
| UL recognition | UL File #E326243 - confirms safety compliance for use in certified industrial and transportation equipment |
Applications
| Automotive Power Input Protection | Industrial CAN Bus Transient Suppression |
|---|---|
|
Use Scenario: 12 V battery rail in engine control units exposed to load dump (ISO 7637-2 Pulse 5a) and alternator ripple. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed upstream of DC-DC converters and microcontroller power supplies. Use Value: Clamps 120 V/200 ms load dump transients to ≤89.0 V, preventing damage to 5 V/3.3 V LDOs and MCU VCC pins. |
Use Scenario: CAN_H/CAN_L differential pair in vehicle body control modules subjected to EFT bursts (IEC 61000-4-4). IC Role / Device Role / Timing Role: Bidirectional TVS across differential bus lines to shunt common-mode surges while preserving signal integrity. Use Value: Symmetrical clamping ensures equal protection on both lines without skewing differential voltage thresholds of CAN transceivers. |
| Smart Lighting Driver Input Stage | PLC Digital I/O Module Protection |
|
Use Scenario: 24 V DC input to LED driver ICs in streetlight controllers experiencing inductive switching spikes from relay coils. IC Role / Device Role / Timing Role: First-line transient absorber between connector and bulk capacitor, limiting voltage rise before filtering. Use Value: Sub-5 ns response captures fast 100 ns–1 µs inductive kick events before they propagate into switching controller gate drivers. |
Use Scenario: 24 V digital input channel in programmable logic controllers interfacing with field sensors prone to wiring-induced surges. IC Role / Device Role / Timing Role: Standoff voltage (53.0 V) exceeds normal 24 V operation while clamping >100 V transients to safe levels. Use Value: Enables direct connection to field wiring without additional series impedance or RC filtering, reducing BOM count and board space. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA | DO-214AA package; 64 V nominal VBR; 600 W rating; slightly higher VC (103 V @ 5.8 A) | Surface-mount footprint requires PCB redesign; lower surge current rating reduces margin in high-energy surge zones | Preferred where SMT assembly and space constraints outweigh through-hole mechanical robustness |
| 1.5KE62CA | Same DO-204AC package; 62 V nominal; 1500 W rating; higher VC (100 V @ 15 A); larger thermal mass | Higher power handling suits infrequent but extreme surges (e.g., lightning coupling); less suitable for repetitive EFT due to slower recovery | Select when system-level surge testing exceeds IEC 61000-4-5 Level 4 and thermal derating is managed via heatsinking |
Compared with SMBJ64CA and 1.5KE62CA, the P6KE62CAH offers optimal balance of AEC-Q101 qualification, through-hole mechanical stability, precise 53.0 V standoff, and 89.0 V clamping - making it ideal for cost-sensitive, high-volume automotive and industrial modules requiring proven reliability without SMT rework or oversized packaging.

FAQ
What does the "CA" suffix indicate in P6KE62CAH?
The "CA" suffix in P6KE62CAH denotes bidirectional configuration - meaning the device provides symmetrical clamping in both polarities, unlike unidirectional "A" variants. This allows placement across floating or AC-coupled nodes without polarity concerns, and is confirmed in TSC's P2203 datasheet Section "Devices for Bipolar Applications".
Is P6KE62CAH suitable for protecting CAN FD interfaces?
Yes, P6KE62CAH is suitable for CAN FD interface protection due to its bidirectional clamping, 53.0 V standoff (well above CAN FD's ±40 V common-mode range), and sub-5 ns response time. Its 89.0 V clamping voltage ensures transceivers rated to 70 V absolute maximum remain within safe operating limits during ISO 16750-2 or IEC 61000-4-4 events.
How does the "H" suffix affect P6KE62CAH's qualification status?
The "H" suffix in P6KE62CAH explicitly indicates AEC-Q101 qualification per TSC's ordering information (Version P2203, Page 4). This includes stress testing for temperature cycling, high-temperature reverse bias, and ESD - distinguishing it from standard P6KE62CA parts not intended for automotive use.
What is the maximum allowable mounting temperature for P6KE62CAH during reflow or wave soldering?
P6KE62CAH uses pure tin-plated leads compliant with J-STD-002, supporting standard wave soldering profiles up to 260°C for 10 seconds. For reflow, its DO-204AC package is rated for peak temperatures ≤260°C per JEDEC J-STD-020 - verified in TSC's mechanical data section and lead finish specifications.
Does P6KE62CAH require external series impedance for effective protection?
No, P6KE62CAH does not require external series impedance to function as a primary clamp - its low dynamic impedance and 600 W surge rating enable direct placement across protected nodes. However, a small series resistor (e.g., 1–10 Ω) may be added to limit peak current in ultra-high-energy scenarios, as noted in TSC's application guidance for inductive load protection.
