Product details
Overview
P6KE15CA-T from Diodes Incorporated is a bidirectional 600W transient voltage suppressor (TVS) diode designed for 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 28A peak pulse current, and DO-15 package with glass-passivated junction-used in automotive body control modules to suppress load-dump and inductive switching transients.
For engineers reviewing the P6KE15CA-T datasheet, P6KE15CA-T pinout, P6KE15CA-T application, or P6KE15CA-T equivalent, this page delivers verified electrical parameters, clamping behavior under 10/1000µs surge, thermal derating curves, DO-15 mechanical dimensions, and direct alternatives for circuit-level ESD/surge protection redesign.
Technical Context
The P6KE15CA-T operates as a bidirectional avalanche diode, triggering conduction symmetrically above ±14.3V (VBR min) and limiting transient voltages to ≤21.2V (VC) during 10/1000µs waveform surges up to 28A. Its glass-passivated die ensures stable breakdown characteristics and low leakage (<5µA at VRWM).
Designed for unclamped transient suppression in non-repetitive events, it exhibits fast response time (<1.0ps), 20°C/W junction-to-case thermal resistance, and full compliance with IEC 61000-4-2 (ESD) and IEC 61000-4-5 (surge) immunity test levels when properly PCB-layout optimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - Sustains single 10/1000µs surge without failure under defined mounting conditions |
| Reverse Standoff Voltage (VRWM) | 12.8V - Maximum continuous DC or RMS voltage before significant leakage begins |
| Breakdown Voltage (VBR) | 14.3V (min) to 15.8V (max) @ 1mA - Confirmed avalanche initiation threshold for bidirectional clamping |
| Clamping Voltage (VC) | 21.2V @ 28A IPP - Maximum voltage seen by protected circuit during worst-case 10/1000µs transient |
| Package | DO-15 - Axial-leaded plastic package rated UL 94V-0, 0.4g mass, 75°C/W junction-to-ambient RθJA |
| Operating Temperature | –55°C to +175°C - Validated performance across automotive under-hood and industrial ambient ranges |
| Leakage Current (IR) | ≤5.0µA @ 12.8V - Ensures minimal standby power loss and signal integrity in high-impedance nodes |
Pinout & Package
DO-15 axial-leaded package: molded plastic body, cathode band not marked on bidirectional variant (P6KE15CA-T), leads solderable per MIL-STD-202 Method 208, moisture sensitivity level 1.

Applications
| Automotive Body Control Module | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting LIN bus transceivers and door module microcontrollers from battery line transients during load dump and jump-start events. IC Role / Device Role: Primary clamping device placed between 12V supply rail and ground, shunting >95% of 100V/50ms load-dump energy. Use Value: Limits rail voltage to ≤21.2V during 28A surge, preventing latch-up or permanent damage to 5V/3.3V LDOs and MCU I/O pins. | Use Scenario: Safeguarding 24V digital input channels in programmable logic controllers exposed to field-wiring inductive kickback. IC Role / Device Role: Front-end TVS on each isolated input channel, mounted directly at connector entry point. Use Value: Clamps 1kV/0.5J surges to <22V within 1ns, preserving optocoupler CTR and enabling reliable state detection under EMI-heavy factory environments. |
| RS-485 Data Line Protection | DC Power Supply Input Stage |
Use Scenario: Bidirectional surge suppression on differential A/B lines of industrial RS-485 networks connected to long cable runs. IC Role / Device Role: Common-mode TVS pair (one per line) referenced to local ground, handling ±15kV ESD and 4kV surge per IEC 61000-4-5. Use Value: Maintains signal integrity below 21.2V clamping level while adding <0.5pF capacitance, avoiding data rate degradation at 10Mbps. | Use Scenario: Secondary-stage overvoltage clamp after primary MOV in 24V DIN-rail power supplies for factory automation equipment. IC Role / Device Role: Precision clamping element downstream of bulk filtering, protecting DC-DC controller ICs from residual transients. Use Value: Provides tighter VC tolerance (±0.3V) than MOVs, ensuring regulated output remains within 5% tolerance during 600W surge events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15CA | Same VRWM (12.8V) and VC (21.2V), but SMB package (surface-mount), 600W rating, lower RθJA (50°C/W) | Requires PCB rework for SMT layout; better thermal performance in dense layouts but lacks axial lead serviceability | Select for automated assembly and space-constrained boards where manual replacement is not required |
| 1.5KE15CA | Same DO-15 package and bidirectional function, but 1500W rating, higher VC (24.4V), larger body (1.5g vs. 0.4g) | Over-specified for 600W use cases; introduces higher clamping voltage and board stress during mechanical shock | Select only when legacy 1.5KE footprint compatibility is mandatory and 24.4V clamping is acceptable |
Compared with SMBJ15CA and 1.5KE15CA, P6KE15CA-T offers optimal balance of axial-leaded serviceability, precise 21.2V clamping, and proven reliability in automotive under-hood environments-making it preferred for repairable, thermally managed, and cost-sensitive 600W protection designs.

FAQ
Is P6KE15CA-T still in active production?
No-Diodes Incorporated has officially discontinued the P6KE15CA-T (DS21502 Rev. 20-4, August 2024). However, Aetrix Electronics maintains limited legacy stock and supports controlled end-of-life procurement with full traceability, including date-code verification and RoHS compliance documentation for each batch.
What is the difference between P6KE15A-T and P6KE15CA-T?
P6KE15A-T is unidirectional (cathode-banded), clamping only negative transients to ground; P6KE15CA-T is bidirectional, clamping both polarities symmetrically. Their VRWM (12.8V), VBR (14.3–15.8V), and VC (21.2V) are identical-only polarity configuration differs, confirmed in Table 1 of DS21502.
Can P6KE15CA-T be used in place of SMAJ15CA?
No-SMAJ15CA uses SMA package (SMT), 400W rating, and different thermal profile (RθJA = 65°C/W). Substitution requires PCB redesign, derating analysis, and validation of clamping margin under 10/1000µs surge due to differing peak power capability and mounting thermal resistance.
What is the maximum allowable lead temperature during soldering?
Per DS21502, maximum steady-state power dissipation at TL = +75°C is 5.0W with 9.5mm lead length mounted on 40mm² copper land. For wave or hand soldering, Diodes specifies peak temperature ≤260°C for ≤10 seconds per J-STD-020, with preheat ≤150°C to avoid thermal shock to the glass-passivated junction.
