Product details
Overview
P6KE13CA-T from Diodes Incorporated is a bidirectional 600W transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a 11.1V reverse standoff voltage (VRWM), 12.4V minimum breakdown voltage (VBR), 18.2V maximum clamping voltage (VC) at 33A peak pulse current, and DO-15 package with glass-passivated junction - deployed in automotive body control modules to suppress load-dump and inductive switching transients.
For engineers reviewing the P6KE13CA-T datasheet, P6KE13CA-T pinout, P6KE13CA-T application, or P6KE13CA-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 bidirectional TVS replacement in industrial power supplies and automotive ECUs.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, enabling clamp-on-both-sides protection without polarity dependency. Its glass-passivated die ensures stable VBR tolerance (±5%) and low leakage (<5µA @ VRWM), critical for low-power sensor interfaces and always-on automotive circuits.
The device sustains 600W peak pulse power for 1.0ms (10/1000µs waveform), with clamping voltage tightly bounded at 18.2V up to 33A IPP - delivering predictable voltage limiting during ISO 7637-2 Pulse 1/2a/5a events. Thermal resistance from junction to ambient is 75°C/W, requiring PCB copper land area design per datasheet layout guidance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W for 1.0ms 10/1000µs waveform - defines maximum transient energy absorption capability |
| Reverse Standoff Voltage (VRWM) | 11.1V - maximum continuous DC or RMS voltage before significant leakage begins |
| Breakdown Voltage (VBR) | 12.4V min @ 1.0mA - onset of avalanche conduction; tight ±5% tolerance ensures consistent trigger point |
| Clamping Voltage (VC) | 18.2V max @ 33A IPP - limits protected circuit voltage during surge, enabling downstream IC survival |
| Peak Pulse Current (IPP) | 33A @ 10/1000µs - quantifies surge current handling before clamping exceeds safe threshold |
| Junction-to-Ambient RθJA | 75°C/W - determines required PCB copper area and airflow for thermal management at 5W steady-state dissipation |
Pinout & Package
Package: DO-15 molded plastic case (UL 94V-0), 0.4g weight, lead length 9.5mm, with cathode band omitted for bidirectional configuration. Marking: "P6KE13CA" only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional avalanche junction | No polarity marking; terminals interchangeable - enables clamp-on-both-polarity surge suppression |
Key Features
| Feature | Design Value |
|---|---|
| 600W peak pulse power rating | Supports robust protection against ISO 7637-2 Pulse 5a (load dump) in 12V automotive systems |
| Glass-passivated junction construction | Ensures long-term stability of VBR and low leakage (<5µA) over temperature and lifetime |
| Bidirectional configuration (suffix 'C') | Eliminates need for polarity-aware placement; simplifies layout in AC-coupled or floating signal paths |
| RoHS-compliant, lead-free finish | Meets EU Directive 2011/65/EU with full exemption documentation; suitable for automotive PPAP |
Applications
| Automotive Body Control Module | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protects microcontroller GPIO and LIN bus transceivers from battery line transients during ignition and load dump. IC Role / Device Role: Primary clamping element placed between VBAT and GND, upstream of LDO input. Use Value: Limits voltage to ≤18.2V during 33A surges, preventing latch-up or oxide breakdown in 5V/3.3V logic. |
Use Scenario: Shields 24V digital input channels from field-wiring induced surges and ESD events. IC Role / Device Role: First-stage TVS on terminal block side of optocoupler input circuit. Use Value: Fast response (<1ns) and low VC ensure downstream opto-IC remains within absolute maximum ratings during 1kV/500A surge tests. |
| Telecom Power Supply Input | Medical Equipment Sensor Interface |
Use Scenario: Guards AC/DC adapter output against back-fed transients from connected equipment. IC Role / Device Role: Bidirectional clamp across +24V and GND outputs prior to filtering stage. Use Value: Symmetric clamping prevents reverse-bias overstress on downstream capacitors and regulators during polarity-reversal faults. |
Use Scenario: Protects analog front-end of patient monitoring ECG leads from defibrillator-induced surges. IC Role / Device Role: Low-leakage (≤5µA) TVS placed directly at connector pins before instrumentation amplifier. Use Value: Maintains signal integrity with <5µA leakage at 11.1V, avoiding DC offset errors in µV-level biopotential measurements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13CA | Same VRWM (11.1V) and VC (18.2V), but 600W rating in SMB package (smaller footprint, higher RθJA = 110°C/W) | Preferred for space-constrained PCBs; requires enhanced thermal relief due to higher thermal resistance | Select when board area is limited and thermal vias/copper pour can compensate for reduced heat dissipation |
| 1.5KE13CA | Same electrical specs but 1500W peak power rating in DO-201AD package; larger size, lower RθJA (50°C/W) | Better suited for high-reliability industrial systems with repetitive surge exposure or elevated ambient temperatures | Choose when system-level testing demands >600W margin or sustained operation above 75°C ambient |
Compared with P6KE13CA-T, SMBJ13CA saves board space but needs careful thermal design, while 1.5KE13CA offers higher surge margin and better thermal performance at the cost of footprint - selection depends on mechanical constraints versus reliability requirements.

FAQ
Is P6KE13CA-T still in active production?
No - Diodes Incorporated has officially discontinued the P6KE13CA-T (Document DS21502 Rev. 20–4 states "OBSOLETE – PART DISCONTINUED"). Aetrix Electronics maintains limited legacy stock for ongoing production support, with full traceability and documented lot history for automotive and industrial customers.
What is the difference between P6KE13A-T and P6KE13CA-T?
P6KE13A-T is unidirectional (cathode-banded), clamping only in reverse bias; P6KE13CA-T is bidirectional (no cathode band), providing symmetrical clamping for both positive and negative transients. Their VRWM, VBR, and VC values are identical, but circuit placement and polarity sensitivity differ.
Can P6KE13CA-T be used in place of SMAJ13CA?
No - SMAJ13CA has lower peak power (400W vs. 600W), different package (SMA vs. DO-15), and higher clamping voltage (21.5V vs. 18.2V). Substitution would reduce surge margin and risk downstream component failure under ISO 7637-2 Pulse 5a conditions.
Does P6KE13CA-T meet AEC-Q200 requirements?
While not explicitly qualified to AEC-Q200, the P6KE13CA-T is constructed using automotive-grade processes (IATF 16949 certified facilities, PPAP-capable), and Diodes confirms suitability for automotive applications requiring change control - qualification testing must be performed by the end customer per their specific stress profiles.
