Product details
Overview
P6KE62CA 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 sub-nanosecond response time (<5.0 ns) with low dynamic impedance - deployed in automotive lighting control modules and industrial PLC I/O protection circuits.
For engineers reviewing the P6KE62CA datasheet, P6KE62CA pinout, P6KE62CA application, or P6KE62CA equivalent, key selection criteria include its bidirectional DO-15 package, 50.2 V standoff voltage, <1 μA leakage at rated VWM, AEC-Q101 qualification (H-suffix variant), and compatibility with IEC 61000-4-4/5 EFT/surge immunity requirements.
Technical Context
The P6KE62CA operates as a silicon avalanche diode configured in bidirectional (symmetrical) mode, enabling clamping in both polarities without external polarity management. Its junction structure supports 600 W non-repetitive peak pulse power per 10/1000 µs waveform and maintains stable VBR (55.8–68.2 V) across temperature via a 0.104 %/°C coefficient.
It meets UL 94V-0 flammability standards in DO-204AC (DO-15) molding compound, uses pure tin-plated leads compliant with J-STD-002 solderability, and is rated for TJ = −55 °C to +175 °C operation - making it suitable for under-hood automotive environments and high-temperature industrial enclosures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 55.8 V / 68.2 V - defines guaranteed avalanche conduction onset range under 1 mA test current; ensures consistent clamping threshold across production lots |
| VWM | 50.2 V - maximum continuous reverse operating voltage before significant leakage; sets safe DC rail margin for 48 V systems |
| VC @ IPPM | 89.0 V @ 7.0 A - clamped voltage during full-rated 10/1000 µs surge; determines protected circuit's maximum transient exposure level |
| PPK | 600 W - peak pulse power handling per standard waveform; enables single-device protection against IEC 61000-4-5 Level 3 (1 kV/2 Ω) surges |
| IR @ VWM | <1 μA - ultra-low reverse leakage at standoff voltage; prevents measurable power loss or bias drift in high-impedance sensing nodes |
| Response Time | <5.0 ns - time from 0 V to VBR under bidirectional transient; ensures protection activation prior to IC damage thresholds (e.g., <10 ns logic input limits) |
| Package | DO-204AC (DO-15) - industry-standard axial-leaded package with 0.400 g mass; compatible with legacy through-hole assembly and manual repair workflows |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, molded epoxy case with cathode band marking for unidirectional variants; P6KE62CA is bidirectional and lacks polarity marking - terminals are functionally symmetric.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction | Either lead serves as input/output terminal; no orientation required during PCB placement - simplifies layout and reduces assembly error risk |
| Lead 1 / Lead 2 | Current path interface | Leads accept 0.375" (9.5 mm) copper pad mounting per JEDEC; supports 5 W steady-state dissipation at TA = 75 °C with specified thermal layout |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability (vibration, temperature cycling, HTRB) - enables use in ASIL-B compliant lighting and body control modules |
| 600 W surge rating (10/1000 µs) | Withstands repeated 1 kV/2 Ω surges per IEC 61000-4-5 without parameter shift - eliminates need for parallel TVS staging in cost-sensitive designs |
| Clamping voltage ≤89.0 V | Ensures downstream 75 V-rated MOSFETs or 60 V-input PMICs remain within absolute maximum ratings during worst-case transients |
| Low dynamic impedance | Minimizes voltage overshoot during fast-rising ESD/EFT events (<1 ns rise time), critical for protecting USB, CAN, and sensor interfaces |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU Directive 2011/65/EU - supports green manufacturing and export compliance for global OEMs |

Use Value: Limits common-mode excursion to ≤89.0 V, preserving transceiver common-mode range (−7 V to +12 V) and preventing false data corruption or receiver shutdown. |
Use Scenario: Suppresses turn-on inrush and AC line transients on 48 V telecom rectifier outputs feeding distributed DC-DC converters. IC Role / Device Role / Timing Role: Rail-to-rail TVS placed at rectifier output capacitor bank to absorb energy from 10/1000 µs surges before reaching downstream POL regulators. Use Value: Absorbs up to 600 W transient energy without derating, eliminating need for series fusing or active crowbar circuits in compact 1RU power shelves. |
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 (Bourns) | DO-214AA (SMB) package; 64 V nominal VBR; 600 W rating; slightly higher VC (93.6 V @ 6.4 A) | Surface-mount footprint requires PCB redesign; better thermal performance in forced-air cooling but lower creepage vs. DO-15 | Select when automated SMT assembly is prioritized and board space is constrained; verify creepage/clearance compliance for 300 VAC systems |
| 1.5KE62CA (ON Semiconductor) | Same DO-15 package; identical 62 V nominal rating; 1500 W peak power (10/1000 µs); higher IPP (16.6 A) and VC (100 V) | Over-spec'd for most 600 W applications; larger junction capacitance may affect high-speed signal integrity | Choose only if legacy 1.5KE footprint reuse is mandatory or system-level surge testing exceeds IEC 61000-4-5 Level 4 (2 kV/2 Ω) |
Compared with SMBJ64CA and 1.5KE62CA, the P6KE62CA offers optimal balance of through-hole manufacturability, AEC-Q101 qualification, and precise 89.0 V clamping - making it preferred for automotive and industrial designs where reliability, legacy assembly, and controlled voltage limiting are jointly critical.

FAQ
What is the maximum clamping voltage of the P6KE62CA under rated surge conditions?
The P6KE62CA clamps to a maximum of 89.0 V when subjected to its rated 7.0 A peak pulse current (IPPM) using the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees that downstream components rated for ≤75 V absolute maximum will remain within safe operating limits during transient events.
Is the P6KE62CA suitable for automotive applications?
Yes, the P6KE62CA is AEC-Q101 qualified (as indicated by the "H" suffix in ordering codes like P6KE62CAH), having passed stress tests for temperature cycling, high-temperature reverse bias, and mechanical shock. It is widely used in automotive LED lighting drivers, body control modules, and infotainment power rails where robustness against load dump and ISO 7637-2 pulses is required.
How does the bidirectional configuration of the P6KE62CA affect PCB layout?
The P6KE62CA has symmetrical terminals with no anode/cathode distinction, so PCB layout requires no polarity orientation - either lead can connect to line or return. This eliminates assembly errors and simplifies routing in differential or AC-coupled protection schemes, unlike unidirectional TVS diodes which mandate strict cathode alignment.
What is the standoff voltage (VWM) of the P6KE62CA, and why does it matter?
The P6KE62CA has a maximum standoff voltage (VWM) of 50.2 V, meaning it remains in high-impedance state up to this DC or RMS voltage level. This parameter ensures reliable operation on 48 V nominal systems while providing sufficient margin to avoid leakage-induced power loss or false triggering during normal operation.
Does the P6KE62CA require derating at elevated ambient temperatures?
Yes, the P6KE62CA must be derated above TA = 25 °C per Figure 2 in the datasheet: its peak pulse power drops linearly to ~50% at 100 °C ambient. For continuous operation at 75 °C, its steady-state power dissipation is limited to 5 W with 0.375" lead lengths on 5 × 5 mm copper pads - thermal design must reflect this constraint.
