Product details
Overview
P6KE62A-T from Diodes Incorporated 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 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 construction with glass-passivated die. It is used in industrial power supplies to protect rectifier outputs against lightning-induced surges.
For engineers reviewing the P6KE62A-T datasheet, P6KE62A-T pinout, P6KE62A-T application, or P6KE62A-T equivalent, this page delivers verified electrical parameters, clamping performance under 1.0ms 8.3ms surge waveforms, thermal derating behavior up to +175°C junction temperature, and direct comparison with functionally aligned TVS alternatives for robust ESD/surge design validation.
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt protector: when transient voltage exceeds VRWM (53.0V), it avalanches into low-impedance conduction to limit downstream voltage to ≤85.0V. Its 1.0ms non-repetitive pulse rating supports IEC 61000-4-5 Level 4 surge immunity testing.
Constructed with glass-passivated silicon die in a DO-15 molded plastic package, it achieves fast response time (<1.0ns), low junction-to-lead thermal resistance (15°C/W), and stable leakage (<5.0µA at VRWM). It is not AEC-Q200 qualified but meets RoHS 2 and halogen-free definitions per Diodes Incorporated standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W for 1.0ms non-repetitive 10/1000µs waveform - defines maximum surge energy absorption capability |
| Reverse Standoff Voltage (VRWM) | 53.0V - maximum continuous DC or RMS voltage before significant leakage begins |
| Breakdown Voltage (VBR) | 58.9V min @ 1.0mA - guaranteed avalanche initiation threshold under standardized test current |
| Clamping Voltage (VC) | 85.0V max @ 7.10A IPP - limits protected circuit voltage during worst-case surge event |
| Peak Pulse Current (IPP) | 7.10A @ 1.0ms - maximum surge current the device safely clamps without failure |
| Junction Temperature Range | –55°C to +175°C - enables operation in harsh industrial or under-hood environments |
| Package | DO-15 - axial-leaded through-hole package with 0.4g mass, UL 94V-0 rated molding compound |
Pinout & Package
DO-15 package: axial-leaded, glass-passivated silicon die in flame-retardant molded plastic housing. Cathode indicated by band; lead length 9.5mm for thermal derating calculations. Moisture sensitivity level 1 (J-STD-020).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lowest potential node; completes clamping path during positive transients |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60A-T | DO-214AA package; 600W rating; VRWM = 60.0V; VC = 96.8V @ 6.2A | Surface-mount alternative with higher clamping voltage and lower IPP; requires PCB real estate optimization | Select when automated SMT assembly is required and board space permits higher VC margin |
| 1.5KE62A-T | DO-201AD package; 1500W rating; VRWM = 53.0V; VC = 101V @ 14.9A | Higher-power through-hole option with larger footprint and greater thermal mass; slower thermal recovery | Select when system-level surge tests exceed 600W or sustained repetitive transients require higher energy handling |
Compared with P6KE62A-T, SMBJ60A-T offers SMT compatibility at the cost of 11.8V higher clamping voltage, while 1.5KE62A-T doubles pulse power capacity but increases package size and thermal inertia-making P6KE62A-T optimal for cost-sensitive, space-constrained 600W-class protection.

FAQ
Is P6KE62A-T still in active production?
No. Diodes Incorporated has officially discontinued the P6KE62A-T and marked it as obsolete per DS21502 Rev. 20-4 (August 2024). Aetrix Electronics maintains limited legacy stock with full traceability and provides last-time-buy support, including documentation and RoHS compliance verification for ongoing production runs.
What is the difference between P6KE62A-T and P6KE62CA-T?
P6KE62A-T is unidirectional (cathode-banded), conducting only during positive transients relative to its cathode; P6KE62CA-T is bidirectional (no band), providing symmetrical clamping for AC-coupled or floating lines. Both share identical VRWM (53.0V), VBR (58.9V min), and VC (85.0V), but bidirectional leakage is doubled for VR ≤10V devices - not applicable here.
Can P6KE62A-T be used in automotive applications?
P6KE62A-T is not AEC-Q200 qualified and lacks PPAP documentation or IATF 16949-controlled manufacturing records. While it may function in non-safety-critical automotive subsystems (e.g., infotainment power rails), Diodes explicitly recommends contacting their automotive team for AEC-Q200-compliant alternatives such as the D3V3Mxx series for qualified designs.
How does thermal derating affect P6KE62A-T's 600W rating?
The 600W peak pulse rating applies only at TA = +25°C. Above +25°C, power must be linearly derated: at +75°C ambient, maximum steady-state dissipation drops to 5.0W (per RθJA = 75°C/W); for pulsed operation, Fig. 4 shows ~75% derating at +100°C ambient, reducing effective IPP to ~5.3A while maintaining safe junction temperature.
