Product details
Overview
P6KE100CA-T from Diodes Incorporated is a bidirectional 600W transient voltage suppressor (TVS) diode designed for overvoltage protection in DC power lines and signal interfaces. 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 die construction - used in industrial power supply input stages to absorb lightning-induced surges.
For engineers reviewing the P6KE100CA-T datasheet, P6KE100CA-T pinout, P6KE100CA-T application, or P6KE100CA-T equivalent, key selection criteria include clamping voltage margin relative to protected IC VDD rails, unidirectional vs. bidirectional polarity requirements for AC-coupled lines, thermal derating at elevated ambient temperatures, and compatibility with automated through-hole assembly on legacy PCBs.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, enabling protection of AC signals or floating DC buses without polarity constraints. Its 1.0mA test current (IT) and 5.0μA max reverse leakage (IR) at VRWM ensure minimal standby power loss while maintaining fast response to transients under 1ns.
The device uses a silicon avalanche structure with glass passivation for stable breakdown characteristics and long-term reliability. Thermal resistance values (RθJA = 75°C/W, RθJL = 15°C/W) indicate suitability for lead-soldered mounting on standard FR-4 with modest copper land area, not requiring heatsinking for single-event surge suppression.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W for 1.0ms non-repetitive 10/1000μs waveform - defines maximum energy absorption capability per transient event |
| Reverse Standoff Voltage | 85.5V - maximum continuous DC or RMS voltage the device blocks without significant leakage |
| Breakdown Voltage | 95.0V min @ 1.0mA - onset voltage where avalanche conduction begins, defining protection threshold |
| Clamping Voltage | 137.0V max @ 4.4A IPP - maximum voltage seen by downstream circuit during specified surge current |
| Package | DO-15 - axial-leaded plastic package rated UL 94V-0, compatible with wave soldering and manual repair |
| Operating Temperature | -55°C to +175°C - supports deployment in under-hood automotive or high-temperature industrial enclosures |
| RoHS Compliance | Lead-free finish, RoHS 2 compliant - meets EU environmental directives without exemptions affecting reliability |
Pinout & Package
DO-15 package: axial-leaded, molded plastic body with cathode band marking omitted for bidirectional variants; leads are tin-plated, solderable per MIL-STD-202 Method 208; weight ≈ 0.4g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional avalanche junction | No polarity designation - either lead functions identically as input/output terminal for transient clamping |
| Leads (both) | Thermal and electrical interface | Provide mechanical attachment and conduct surge current to PCB copper; RθJL = 15°C/W enables effective heat transfer to board traces |
Key Features
| Feature | Design Value |
|---|---|
| 600W peak pulse rating | Supports IEC 61000-4-5 Level 4 (4kV line-to-line) surge immunity without cascaded protection stages |
| Glass passivated die | Ensures stable VBR over temperature and lifetime, minimizing parameter drift in harsh environments |
| Bidirectional configuration | Eliminates need for polarity-aware layout; protects AC-coupled data lines or transformer secondaries |
| Fast response time | Sub-nanosecond turn-on enables clamping before sensitive downstream components experience overvoltage stress |
| UL 94V-0 flammability rating | Plastic housing resists ignition during sustained overvoltage fault conditions, enhancing system safety compliance |
Applications
| Industrial Power Input Protection | Automotive Body Control Module |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100CA | Same VRWM (85.5V) and VC (137V), but SMC package (surface-mount), 600W rating, lower RθJA (50°C/W) | Requires rework of PCB footprint; better thermal performance in space-constrained designs | Select when upgrading to SMT assembly or improving thermal headroom in high-density layouts |
| P6SMB100CA | Identical electrical specs and SMB package; same 600W rating, but slightly higher IR (10μA vs. 5μA) at VRWM | Drop-in replacement for SMB footprint; identical pinout and mounting but different package outline | Choose for direct SMB socket compatibility where DO-15 lead spacing is incompatible with existing tooling |
Compared with P6KE100CA-T, SMBJ100CA offers superior thermal dissipation in surface-mount form, while P6SMB100CA provides identical protection performance in a smaller footprint - both require layout revision but eliminate through-hole assembly steps and improve board-level reliability under vibration.

FAQ
Is P6KE100CA-T still in active production?
No - Diodes Incorporated has officially discontinued the P6KE100CA-T and marked it as obsolete per DS21502 Rev. 20-4 (August 2024). Aetrix Electronics maintains limited legacy stock with full traceability and offers engineering support for migration paths to active alternatives like SMBJ100CA or P6SMB100CA.
What is the difference between P6KE100A-T and P6KE100CA-T?
P6KE100A-T is unidirectional (cathode-banded), clamping only negative transients relative to its marked cathode; P6KE100CA-T is bidirectional (no cathode band), providing symmetrical clamping for both polarities - critical for AC or floating DC applications where polarity is undefined or reverses.
Can P6KE100CA-T be used in automotive AEC-Q200 qualified designs?
While the P6KE100CA-T itself is not AEC-Q200 certified, Diodes states that automotive-grade versions meeting AEC-Q200 are available upon request with PPAP documentation and IATF 16949 manufacturing - contact Diodes or Aetrix for qualified equivalents with full automotive change control and qualification records.
How does thermal derating affect P6KE100CA-T's surge capability at 105°C ambient?
Per Figure 4 in DS21502, at TA = +105°C, P6KE100CA-T's peak pulse power is derated to ~65% of 600W (≈390W); this reduces maximum clamping current to ~3.6A at 137V - designers must verify worst-case surge energy remains within this derated envelope for reliable operation.
