Product details
Overview
P6KE36CA-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 30.8V reverse standoff voltage (VRWM), 34.2V minimum breakdown voltage (VBR), 49.9V maximum clamping voltage (VC) at 12A peak pulse current, and DO-15 package with glass-passivated junction - deployed in automotive body control modules to suppress load-dump transients.
For engineers reviewing the P6KE36CA-T datasheet, P6KE36CA-T pinout, P6KE36CA-T application, or P6KE36CA-T equivalent, key selection criteria include clamping voltage margin relative to protected IC VCC, unidirectional vs. bidirectional polarity requirements, 1.0ms 600W pulse handling capability, and DO-15 lead-form compatibility with legacy PCB footprints.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, enabling protection of AC-coupled or floating signal paths without polarity constraints. Its glass-passivated die ensures stable breakdown characteristics and low leakage (<5µA @ VRWM) over temperature (-55°C to +175°C).
The device responds within <1.0ps to ESD and surge events, clamping transients before downstream components experience overstress. Its 600W peak pulse rating (tP = 1.0ms, 10/1000µs waveform) is derated linearly above +25°C ambient per Figure 4 in DS21502 Rev. 20–4.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W (1.0ms non-repetitive, defines maximum transient energy absorption) |
| Reverse Standoff Voltage (VRWM) | 30.8V (maximum continuous DC or RMS voltage before significant leakage) |
| Breakdown Voltage (VBR) | 34.2V min / 37.8V max @ 1.0mA (voltage at which device enters avalanche conduction) |
| Clamping Voltage (VC) | 49.9V max @ 12.0A IPP (maximum voltage seen by protected circuit during 1.0ms surge) |
| Peak Pulse Current (IPP) | 12.0A (peak current supported at rated clamping voltage under 1.0ms pulse) |
| Junction Temperature Range | -55°C to +175°C (enables use in under-hood automotive and industrial environments) |
| Package | DO-15 (axial-leaded, 0.4g weight, UL 94V-0 molded plastic, compatible with wave soldering) |
Pinout & Package
DO-15 package: axial-leaded, glass-passivated silicon junction, cathode band not marked on bidirectional version (P6KE36CA-T); leads are tin-plated, solderable per MIL-STD-202 Method 208.

| Anode | Current entry terminal in forward bias; clamping node in negative transient | Connected to line being protected; symmetrical with cathode for bidirectional operation |
| Cathode | Current exit terminal in forward bias; clamping node in positive transient | Connected to line being protected; functionally identical to anode in bidirectional mode |
Key Features
| Feature | Design Value |

| Glass-passivated junction | Ensures stable VBR and low IR drift over 1000+ thermal cycles (-55°C/+175°C) |
| RoHS-compliant lead finish | Meets EU Directive 2011/65/EU with full exemption documentation per Diodes' Green Policy |
Applications
| Automotive Body Control Module | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting LIN bus transceivers and microcontroller GPIOs from battery reverse-connection and load-dump events in door module ECUs. IC Role / Device Role / Timing Role: Primary clamping element placed between LIN line and ground, conducting only during >34.2V transients. Use Value: Limits voltage to ≤49.9V during 12A surge, preventing damage to 3.3V/5V transceivers with 50V absolute max ratings. |
Use Scenario: Safeguarding 24V digital input channels on programmable logic controllers exposed to field-wiring inductive kickback. IC Role / Device Role / Timing Role: Shunt protector mounted directly at terminal block, clamping transients before signal conditioning circuitry. Use Value: Absorbs up to 600W for 1ms, suppressing >100V spikes from solenoid de-energization without latch-up or degradation. |
| DC Power Supply Input Stage | Telecom Line Interface |
Use Scenario: Secondary overvoltage clamp on 36V DC input rail of PoE-powered network switches after primary DC-DC converter. IC Role / Device Role / Timing Role: Fast-response shunt device triggered when upstream regulator fails or experiences overshoot. Use Value: Clamps 36V rail to 49.9V within <1ps, protecting 40V-rated MOSFETs and capacitors downstream. |
Use Scenario: Bidirectional surge suppression on RS-485 differential pairs in outdoor base station backhaul links. IC Role / Device Role / Timing Role: Symmetric protection element across A/B lines referenced to signal ground. Use Value: Maintains signal integrity by limiting common-mode transients to <50V while adding <0.5pF capacitance per line (per Fig. 2). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36CA | Same VRWM/VBR/VC specs but SMB package (surface-mount, 600W rating) | Requires PCB redesign for SMT footprint; better thermal performance at high ambient | Select when board space is constrained and reflow soldering is available |
| 1.5KE36CA | Same electrical specs but 1500W peak pulse rating and DO-201AD package | Higher surge margin for harsher environments (e.g., railway traction power) | Select when system-level testing requires >1000W surge immunity per IEC 61000-4-5 Level 4 |
Compared with P6KE36CA-T, SMBJ36CA offers superior board-area efficiency and thermal resistance (RθJA ≈ 50°C/W vs. 75°C/W), while 1.5KE36CA provides 2.5× higher pulse energy tolerance but requires larger mounting area and higher assembly cost.

FAQ
Is P6KE36CA-T still in active production?
No - Diodes Incorporated has officially discontinued the P6KE36CA-T (DS21502 Rev. 20–4 states "OBSOLETE – PART DISCONTINUED"). Aetrix Electronics maintains limited legacy stock and supports last-time buy programs with full traceability and extended warranty terms for qualified industrial and automotive customers.
What is the difference between P6KE36A-T and P6KE36CA-T?
P6KE36A-T is unidirectional (cathode-banded, protects against positive-only transients), while P6KE36CA-T is bidirectional (no cathode band, protects both polarities). Their VRWM (30.8V), VBR (34.2V min), and VC (49.9V) are identical, but bidirectional operation enables AC or floating-line protection without polarity routing constraints.
Can P6KE36CA-T be used in place of P6KE33CA-T?
No - P6KE36CA-T has higher VRWM (30.8V vs. 28.2V) and VBR (34.2V vs. 31.4V), resulting in 3.7V higher clamping onset. Substituting it for P6KE33CA-T may leave 33V-rated circuits unprotected during lower-energy transients that trigger the 33V device but not the 36V variant.
What is the thermal resistance from junction to ambient (RθJA) for P6KE36CA-T?
The typical RθJA is 75°C/W when mounted on a copper land area of 40mm² with 9.5mm lead length (per DS21502 Rev. 20–4, Thermal Characteristics table). This value assumes standard DO-15 PCB layout; actual performance improves with larger copper pours or forced-air cooling.
