Product details
Overview
P6KE100A-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 85.5V reverse standoff voltage (VRWM), 95.0V minimum breakdown voltage (VBR), 137.0V maximum clamping voltage (VC) at 4.4A peak pulse current, and DO-15 package with glass-passivated junction - deployed in industrial power supplies and automotive body control modules.
For engineers reviewing the P6KE100A-T datasheet, P6KE100A-T pinout, P6KE100A-T application, or P6KE100A-T equivalent, this page delivers verified electrical parameters, clamping performance under 1.0ms 600W pulses, thermal resistance values (RθJA = 75°C/W), and direct replacement guidance for legacy surge protection designs.
Technical Context
This unidirectional TVS diode operates as a fast-acting shunt clamp during ESD or lightning-induced transients, triggering at ≥95.0V (VBR) and limiting downstream voltage to ≤137.0V (VC) at 4.4A IPP. Its glass-passivated die ensures stable leakage (<5.0µA at VRWM) and repeatable breakdown behavior across temperature.
The device complies with IEC 61000-4-2 (ESD) and IEC 61000-4-5 (surge) immunity requirements when used with appropriate series impedance. Its DO-15 package supports lead-free reflow soldering and meets UL 94V-0 flammability rating for board-level safety compliance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W for 1.0ms non-repetitive 10/1000µs waveform - defines maximum transient energy absorption capability |
| Reverse Standoff Voltage (VRWM) | 85.5V - maximum continuous DC or RMS voltage the device blocks without clamping |
| Breakdown Voltage (VBR) | 95.0V min @ 1.0mA - precise voltage threshold where avalanche conduction begins |
| Clamping Voltage (VC) | 137.0V max @ 4.4A IPP - limits protected circuit voltage during worst-case surge event |
| Leakage Current (IR) | ≤5.0µA @ 85.5V - ensures negligible standby power loss and signal integrity in high-impedance circuits |
| Thermal Resistance (RθJA) | 75°C/W - determines junction temperature rise under steady-state power dissipation (PD = 5.0W at TL = +75°C) |
Pinout & Package
Package: DO-15 molded plastic case with cathode band marking; UL 94V-0 rated; 0.4g weight; lead finish RoHS-compliant and solderable per MIL-STD-202, Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current sink during clamping | Connected to protected line; conducts surge current to ground when VC exceeded |
| Cathode | Reference terminal / polarity indicator | Marked with band; ties to higher-potential rail (e.g., VCC); defines unidirectional conduction direction |
Key Features
| Feature | Design Value |
|---|---|
| 600W peak pulse power rating | Enables robust protection against IEC 61000-4-5 Level 4 (4kV) surges on 12V/24V systems |
| Glass-passivated junction | Ensures long-term parameter stability and low parameter drift over 1000+ surge events |
| Fast response time (<1.0ps) | Clamps transients before sensitive ICs experience overstress - critical for microcontroller I/O protection |
| RoHS-compliant lead finish | Supports lead-free reflow assembly without compromising solder joint reliability or thermal cycling performance |
Applications
| Industrial Power Supply Input Protection | Automotive Body Control Module (BCM) |
|---|---|
Use Scenario: 24V DC input stage of programmable logic controller (PLC) power supply exposed to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Primary shunt clamp placed upstream of DC-DC converter input to limit voltage excursion during 12V/24V system transients. Use Value: Clamps 137.0V max at 4.4A, preventing damage to upstream rectifier and downstream buck controller rated for 40V absolute max. |
Use Scenario: LIN bus line protection in door module where ESD events occur during connector mating/unmating. IC Role / Device Role / Timing Role: Unidirectional TVS tied between LIN line and chassis ground to divert ESD current away from transceiver IC. Use Value: Sub-1ns response ensures clamping occurs before LIN transceiver's internal protection triggers, preserving signal integrity during ±8kV contact discharge. |
| Telecom Remote Radio Unit (RRU) DC Feed | Medical Infusion Pump Motor Driver |
Use Scenario: -48V DC power feed to outdoor base station radio unit subject to induced lightning surges. IC Role / Device Role / Timing Role: First-stage surge protector on DC input before isolation and regulation stages. Use Value: 600W rating handles 10/1000µs surges up to 4kV; DO-15 footprint allows compact placement near entry connector. |
Use Scenario: H-bridge gate drive supply rail in battery-powered infusion pump with brushed DC motor. IC Role / Device Role / Timing Role: Clamp on 12V motor supply to suppress inductive kickback from motor commutation spikes. Use Value: 137.0V clamping prevents latch-up in gate driver ICs rated for 16V max supply, ensuring safe restart after transient. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A-T3G | DO-214AA package; lower RθJA (50°C/W); same VRWM (85.5V), slightly lower VC (136.0V @ 4.4A) | Better thermal performance in high-density layouts; requires PCB pad redesign due to SMC footprint | Select when board space permits SMC package and thermal management is prioritized over legacy DO-15 compatibility |
| 1.5KE100A | Same DO-15 package; higher PPK (1500W); higher VC (147.0V @ 12.5A); slower response due to larger junction capacitance | Used where higher surge margin is required but tighter clamping is less critical (e.g., AC mains input) | Select only if system-level testing confirms 147.0V clamping remains within downstream IC tolerances |
Compared with SMBJ100A-T3G, P6KE100A-T offers drop-in DO-15 compatibility and lower cost, while 1.5KE100A trades tighter clamping for higher surge capacity - making P6KE100A-T optimal for cost-sensitive, space-constrained 24V industrial controls where 137.0V clamping is sufficient.

FAQ
Is P6KE100A-T still in active production?
No - Diodes Incorporated has marked the entire P6KE6V8(C)A–P6KE400(C)A family as obsolete per DS21502 Rev. 20-4 (August 2024). Aetrix Electronics maintains limited legacy stock and supports last-time-buy programs with full traceability and documentation for ongoing production runs.
What is the difference between P6KE100A-T and P6KE100CA-T?
P6KE100A-T is unidirectional with cathode band marking and conducts only in reverse bias; P6KE100CA-T is bidirectional, lacks cathode marking, and clamps symmetrically for AC-coupled lines like telecom data pairs or audio signals - both share identical VRWM (85.5V) and VC (137.0V).
Can P6KE100A-T be used in surface-mount designs?
No - it uses the axial DO-15 through-hole package and is not compatible with SMT reflow or pick-and-place processes. For SMT equivalents, consider SMBJ100A-T3G (DO-214AA) or SMCJ100A (DO-214AB), which offer matching electrical specs in surface-mount form factors.
What derating applies above +25°C ambient?
Per Figure 4 in DS21502, P6KE100A-T's peak pulse power derates linearly: at +75°C TA, maximum PPK drops to ~450W; at +125°C TA, it falls to ~225W. Steady-state power must also follow Figure 5, limiting PD to ~2.5W at +125°C lead temperature.
