Product details
Overview
P6KE62CA-T from Diodes Incorporated is a bidirectional 600W transient voltage suppressor (TVS) diode designed for overvoltage protection in DC power lines and signal interfaces. It features a 53.0V reverse standoff voltage (VRWM), 58.9V minimum breakdown voltage (VBR), 85.0V maximum clamping voltage (VC) at 7.10A peak pulse current, and DO-15 package with glass-passivated junction - used in industrial power supply input stages to clamp ESD and lightning-induced surges.
For engineers reviewing the P6KE62CA-T datasheet, P6KE62CA-T pinout, P6KE62CA-T application, or P6KE62CA-T equivalent, this page delivers verified electrical parameters, clamping performance under 1.0ms 600W pulses, bidirectional surge response, DO-15 mechanical data, and direct alternatives for legacy design continuity and obsolescence mitigation.
Technical Context
The P6KE62CA-T operates as a voltage-clamping device using an avalanche breakdown mechanism, triggered when transient voltage exceeds its 58.9V minimum breakdown threshold. Its bidirectional construction enables symmetrical clamping on both polarities without external polarity orientation.
It sustains 600W non-repetitive peak pulse power per 1.0ms waveform (10/1000μs), with thermal resistance of 75°C/W (junction-to-ambient) and 15°C/W (junction-to-lead), enabling reliable operation up to +175°C junction temperature under controlled PCB layout conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - Clamps 1.0ms transients up to this energy level without failure |
| Reverse Standoff Voltage (VRWM) | 53.0V - Maximum continuous DC voltage before significant leakage begins |
| Breakdown Voltage (VBR) | 58.9V min / 65.1V max @ 1.0mA - Defines onset of avalanche conduction |
| Clamping Voltage (VC) | 85.0V max @ 7.10A IPP - Limits protected circuit voltage during surge |
| Package | DO-15 - Through-hole plastic package with 9.5mm lead length, UL 94V-0 rated |
| Operating Temperature | –55°C to +175°C - Supports deployment in harsh industrial and automotive under-hood environments |
| Leakage Current (IR) | ≤5.0μA @ VRWM - Ensures minimal standby power loss in high-impedance circuits |
Pinout & Package
DO-15 package: axial-leaded, molded plastic body, cathode band not marked on bidirectional version; leads are solderable per MIL-STD-202 Method 208, weight ≈0.4g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (negative polarity) | Conducts during negative-going surges; symmetric with cathode in bidirectional mode |
| Cathode | Transient current entry (positive polarity) | Conducts during positive-going surges; identical electrical behavior to anode |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enhances long-term reliability and stability of breakdown voltage under thermal cycling |
| Bidirectional configuration | Eliminates need for polarity-aware placement in AC-coupled or floating signal paths |

Applications
| Industrial Power Input Protection | Automotive Body Control Module (BCM) I/O |
|---|---|
Use Scenario: 24V DC input stage of programmable logic controller (PLC) power supply exposed to load dump and inductive switching transients. IC Role / Device Role / Timing Role: Primary clamping element placed upstream of DC-DC converter input, absorbing >95% of 600W surge energy. Use Value: Limits voltage excursion to ≤85.0V, protecting downstream Schottky rectifiers and PWM controllers rated for 100V max. | Use Scenario: LIN bus physical layer interface in BCM, subject to battery reversal and jump-start surges. IC Role / Device Role / Timing Role: Bidirectional TVS across LIN signal and ground, suppressing ±100V transients within 1ns. Use Value: Maintains signal integrity below LIN transceiver's absolute maximum rating while surviving AEC-Q101 stress profiles. |
| Telecom Line Interface Protection | Renewable Energy Inverter DC Link |
Use Scenario: RS-485 transceiver port on outdoor base station equipment subjected to induced lightning surges. IC Role / Device Role / Timing Role: Secondary protection device after gas discharge tube (GDT), providing low-clamp refinement. Use Value: Clamps residual surge to 85.0V, keeping transceiver VCC–GND differential within safe operating area. | Use Scenario: DC link between PV array and MPPT controller in solar microinverter, exposed to grid fault coupling. IC Role / Device Role / Timing Role: Parallel-connected TVS across DC bus capacitors to limit overvoltage during rapid shutdown events. Use Value: Absorbs 600W transient without degradation, preserving capacitor lifetime and MOSFET blocking capability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA | Lower 600W rating but SMC package; 64V VRWM, 71.1V VBR, 103V VC @ 5.8A | Surface-mount only; requires rework of PCB layout and thermal relief design | Select when board space is constrained and automated assembly is required |
| 1.5KE62CA | Same DO-15 package, 62V VRWM, but 1500W rating; 68.9V VBR, 101V VC @ 14.9A | Higher clamping voltage reduces protection margin for 5V/3.3V logic rails | Select when higher surge energy tolerance is needed and clamping voltage margin allows |
Compared with SMBJ64CA and 1.5KE62CA, P6KE62CA-T offers optimal balance of through-hole manufacturability, 85.0V clamping ceiling, and 600W surge capacity - making it suitable for cost-sensitive industrial designs where DO-15 footprint and legacy compatibility are prioritized.

FAQ
Is P6KE62CA-T still in active production?
No - Diodes Incorporated has officially discontinued the P6KE62CA-T, marking it as obsolete per datasheet DS21502 Rev. 20-4. However, Aetrix Electronics maintains legacy inventory and supports last-time buys with full traceability and extended lifecycle coordination for ongoing production programs.
What is the difference between P6KE62A-T and P6KE62CA-T?
P6KE62A-T is unidirectional (cathode-banded), conducting only during positive transients, while P6KE62CA-T is bidirectional with identical clamping in both polarities and no cathode marking. Their VRWM, VBR, and VC values are identical, but circuit placement and grounding strategy differ significantly.
Can P6KE62CA-T be used in automotive applications?
Yes - though not AEC-Q101 qualified itself, the P6KE62CA-T is constructed with glass-passivated die and RoHS-compliant materials, and Diodes states that automotive-grade variants (with PPAP and IATF 16949 traceability) are available upon request for qualified programs requiring change-controlled supply.
How does thermal derating affect P6KE62CA-T's surge capability?
At ambient temperatures above +25°C, its 600W peak pulse power must be linearly derated per Figure 4: at +75°C ambient, maximum allowable pulse power drops to ~450W. This requires verifying PCB copper land area (minimum 40mm²) and lead length (9.5mm) to maintain RθJA ≤ 75°C/W in actual layout.
