Product details
Overview
P6KE15A-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 12.8V reverse standoff voltage (VRWM), 14.3V minimum breakdown voltage (VBR), 21.2V maximum clamping voltage (VC) at 28.0A peak pulse current, and DO-15 axial package-used in industrial power supplies, automotive body control modules, and telecom interface protection.
For engineers reviewing the P6KE15A-T datasheet, P6KE15A-T pinout, P6KE15A-T application, or P6KE15A-T equivalent, key selection criteria include clamping voltage margin relative to protected IC VCC, 1.0ms 600W surge capability, unidirectional polarity, DO-15 mechanical fit, and compliance with IEC 61000-4-5 Level 3 surge immunity requirements.
Technical Context
This TVS operates as a voltage-clamped shunt protector: under normal bias it presents <5.0µA leakage at 12.8V; during transients exceeding 14.3V, it avalanches rapidly (<1ns response) to clamp the line at ≤21.2V while diverting up to 28.0A of 1.0ms 8/20µs surge current. Its glass-passivated junction ensures stable breakdown characteristics across temperature.
The device is rated for -55°C to +175°C operating range, with thermal resistance of 75°C/W (junction-to-ambient) and 20°C/W (junction-to-case), enabling reliable operation in high-temperature environments when mounted on ≥40mm² copper land. Steady-state power dissipation is 5.0W at TL = +75°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W (1.0ms non-repetitive 8/20µs waveform; defines maximum surge energy absorption) |
| Reverse Standoff Voltage | 12.8V (maximum continuous DC or RMS voltage before significant leakage; sets upper limit for protected circuit operating voltage) |
| Breakdown Voltage | 14.3V min @ 1.0mA (avalanche initiation threshold; ensures reliable triggering above normal operating voltage) |
| Clamping Voltage | 21.2V max @ 28.0A (voltage seen by downstream circuit during full-rated surge; determines protection margin for 15V logic/rails) |
| Package | DO-15 (axial leaded, 5.5–7.62mm body length; compatible with through-hole wave soldering and manual prototyping) |
| Operating Temperature | -55°C to +175°C (supports under-hood automotive, industrial motor drives, and outdoor telecom equipment) |
| RoHS Compliance | Lead-free, Halogen-free, compliant with EU Directive 2011/65/EU (RoHS 2); suitable for green manufacturing programs |
Pinout & Package
Package: DO-15 molded plastic case (UL 94V-0 rated), 0.4g weight, with plating per MIL-STD-202 Method 208. Cathode band identifies the cathode terminal; anode is unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Current entry point during forward conduction; connected to protected line ground or low-side reference | Provides low-impedance path to ground during transient events; must be routed with minimal inductance to maintain clamping performance |
| Cathode (banded end) | Current exit point during avalanche; connected to protected positive rail or signal line | Defines polarity: unidirectional operation only; reverse connection renders device ineffective against positive surges |
Key Features
| Feature | Design Value |
|---|---|
| 600W peak pulse rating | Supports IEC 61000-4-5 Level 3 (1kV/2kV line-earth) surge testing without degradation |
| Glass passivated die | Ensures stable VBR over 1000+ surge cycles and long-term reliability in humid environments |
| Fast response time | Sub-nanosecond turn-on enables protection of fast-edge microcontrollers and CAN transceivers |
| DO-15 mechanical compatibility | Direct replacement for legacy 1N6267–1N6279 series; fits standard axial footprint and pick-and-place tooling |
| Low clamping ratio (VC/VBR ≈ 1.48) | Minimizes voltage overshoot during surge, reducing stress on downstream 16V-rated ICs and regulators |
Applications
| Industrial Power Supply Protection | Automotive Body Control Module |
|---|---|
Use Scenario: 12V DC input rail of programmable logic controller (PLC) power supply subjected to load dump and inductive switching transients. IC Role / Device Role / Timing Role: Primary shunt TVS placed at bulk capacitor input to clamp surges before they reach DC/DC converters and microcontrollers. Use Value: Limits transient voltage to ≤21.2V, preserving 24V-rated input stages and preventing latch-up in downstream 3.3V/5V logic. | Use Scenario: LIN bus transceiver power line in door module exposed to battery disconnect spikes and ESD events. IC Role / Device Role / Timing Role: Unidirectional clamping device between VBAT and GND, protecting transceiver VCC pin from >15V excursions. Use Value: Maintains LIN signal integrity by suppressing 100A/1ms surges within 21.2V ceiling, meeting ISO 16750-2 pulse 5a requirements. |
| Telecom Interface Surge Protection | AC-DC Adapter Input Stage |
Use Scenario: RS-485 transceiver power supply in outdoor base station exposed to lightning-induced surges on shared power bus. IC Role / Device Role / Timing Role: Secondary-level TVS on +5V bias rail, coordinated with upstream MOV and gas discharge tube. Use Value: Provides precise low-voltage clamping (21.2V) to protect 5V LDOs and transceivers where MOV let-through voltage is too high. | Use Scenario: Input rectifier stage of universal-input (90–264VAC) wall adapter experiencing differential-mode surges. IC Role / Device Role / Timing Role: DC-side TVS across bulk capacitor to absorb residual energy after bridge rectification and filtering. Use Value: Absorbs 600W surge energy without thermal runaway, extending capacitor lifetime and avoiding catastrophic failure modes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15A-T | Same VRWM (12.8V) and VC (21.2V), but SMC package (surface-mount), 600W rating, lower RθJA (50°C/W) | Requires PCB rework for SMT assembly; unsuitable for through-hole legacy designs or manual repair | Select when board space is constrained and automated SMT production is available. |
| 1.5KE15A | Same DO-15 package and electrical specs, but obsolete per ON Semiconductor DS; no AEC-Q200 qualification path | Lacks documented automotive change control and PPAP support; not recommended for new automotive designs | Acceptable for cost-sensitive industrial prototypes where automotive compliance is not required. |
Compared with SMBJ15A-T and 1.5KE15A, P6KE15A-T offers verified DO-15 through-hole compatibility, Diodes' IATF 16949 manufacturing, and direct AEC-Q200 qualification pathway-making it preferred for automotive BOMs requiring traceability and long-term supply continuity.

FAQ
What is the difference between P6KE15A-T and P6KE15CA-T?
P6KE15A-T is unidirectional, with cathode band marking and clamping only for positive transients on the cathode side; P6KE15CA-T is bidirectional, symmetrically clamps both polarities, lacks cathode band, and has identical VRWM (12.8V) and VC (21.2V) but double IR limit (10µA vs. 5µA) for VR ≤10V devices-though this does not apply here since 12.8V >10V.
Can P6KE15A-T be used in place of P6KE13A-T?
No-P6KE13A-T has lower VRWM (11.1V), VBR (12.4V min), and VC (18.2V), making it suitable for 12V systems with tighter clamping margins; substituting P6KE15A-T raises clamping voltage by 3.0V, risking overvoltage damage to 15V-rated components downstream.
Is P6KE15A-T qualified for automotive applications?
Yes-Diodes manufactures P6KE15A-T in IATF 16949-certified facilities and supports AEC-Q200 qualification upon request; it meets automotive-grade change control, PPAP documentation, and high-temperature operation (-55°C to +175°C), though final qualification requires customer-specific test execution.
What is the maximum surge current P6KE15A-T can handle repeatedly?
P6KE15A-T is rated for non-repetitive 1.0ms pulses; repetitive surges require derating per Figure 4-e.g., at +100°C ambient, peak pulse power drops to ~50% (300W), limiting safe IPP to ~20A; for >100 pulses/hour, thermal accumulation necessitates PCB copper area ≥100mm² and forced airflow.
