Product details
Overview
P6KE110CA-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 94.0V reverse standoff voltage (VRWM), 105.0–116.0V breakdown range (VBR), 152.0V max clamping voltage (VC) at 4.0A peak pulse current (IPP), and DO-15 package with glass-passivated junction - used in industrial power supplies and automotive body electronics.
For engineers reviewing the P6KE110CA-T datasheet, P6KE110CA-T pinout, P6KE110CA-T application, or P6KE110CA-T equivalent, key selection criteria include clamping voltage margin vs. system rail, unidirectional/bidirectional polarity match, 1.0ms pulse waveform compliance, and DO-15 thermal derating above +25°C ambient.
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 VBR tolerance (±5% typical) and low leakage (<5.0µA @ VRWM) under steady-state bias.
The device responds to transients within <1.0ns, clamping 8/20µs surges up to 600W peak power while maintaining VC ≤152.0V at IPP = 4.0A. Thermal resistance from junction to ambient is 75°C/W, requiring PCB copper area management for sustained surge duty cycles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W for 1.0ms non-repetitive 10/1000µs waveform - defines maximum transient energy absorption capability |
| Reverse Standoff Voltage (VRWM) | 94.0V - maximum continuous DC or RMS voltage before significant leakage begins |
| Breakdown Voltage (VBR) | 105.0–116.0V @ IT = 1.0mA - onset of avalanche conduction; tight 10.5% tolerance enables precise overvoltage thresholding |
| Max Clamping Voltage (VC) | 152.0V @ IPP = 4.0A - limits protected circuit voltage during surge; 58.0V headroom above VRWM |
| Peak Pulse Current (IPP) | 4.0A @ VC = 152.0V - quantifies surge current handling at rated clamping level |
| Junction-to-Ambient RθJA | 75°C/W - determines temperature rise under steady-state power; requires thermal relief on PCB for >1W dissipation |
| Package | DO-15 - axial-leaded, through-hole plastic package rated UL 94V-0; compatible with wave soldering and manual assembly |
Pinout & Package
DO-15 package: axial-leaded, molded plastic body (UL 94V-0), 0.4g mass, 9.5mm lead length standard. Bidirectional marking: type number only (no cathode band).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (negative polarity) | Conducts during negative-going surges; symmetrical with Cathode in bidirectional operation |
| Cathode | Transient current entry (positive polarity) | Conducts during positive-going surges; identical electrical behavior to Anode due to bidirectional construction |
Key Features
| Feature | Design Value |
|---|---|
| 600W peak pulse rating | Supports IEC 61000-4-5 Level 4 (4kV) surge immunity in properly filtered front-end designs |
| Glass-passivated junction | Ensures long-term VBR stability and low parameter drift across -55°C to +175°C operating range |
| Bidirectional configuration | Protects AC signals, differential buses (e.g., RS-485), or floating DC rails without polarity dependency |
| RoHS-compliant lead finish | Meets EU Directive 2011/65/EU; compatible with Pb-free reflow and wave soldering processes |
Applications
| Industrial Power Input Protection | Automotive Body Control Module |
|---|---|
Use Scenario: 24V DC input stage of programmable logic controller exposed to load dump and inductive switching transients. IC Role / Device Role / Timing Role: Primary overvoltage clamp limiting rail voltage to ≤152V during 10/1000µs surges up to 4A. Use Value: Prevents damage to downstream DC-DC converters and microcontrollers by holding voltage below their absolute maximum ratings. | Use Scenario: LIN bus line protection in door module where ESD and battery reversal events occur. IC Role / Device Role / Timing Role: Bidirectional transient clamp on LIN physical layer, responding within <1ns to ±8kV contact ESD per ISO 10605. Use Value: Maintains signal integrity during fast transients while adding <0.5pF parasitic capacitance at 0V bias. |
| AC-DC Adapter Secondary Side | RS-485 Transceiver Interface |
Use Scenario: Output rectifier protection in 48V telecom adapter subject to output short-circuit recovery spikes. IC Role / Device Role / Timing Role: Fast-clamping element placed across secondary winding or post-rectifier filter capacitor. Use Value: Limits voltage overshoot to 152V during 100ns–1µs recovery transients, avoiding MOSFET or optocoupler breakdown. | Use Scenario: Common-mode surge suppression on RS-485 data lines in factory automation networks. IC Role / Device Role / Timing Role: Bidirectional clamp between A/B lines and ground, shunting common-mode surges exceeding 94V. Use Value: Enables robust 250kbps communication under IEC 61000-4-4 EFT bursts without receiver latch-up. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110CA | Same VRWM (94V) and VC (152V), but 600W rating in SMB package; lower RθJA (50°C/W) | Surface-mount only; unsuitable for through-hole legacy designs or high-vibration environments requiring axial leads | Select when board space is constrained and automated SMT assembly is available |
| P6KE110A | Unidirectional version; identical VRWM/VBR/VC but conducts only in one polarity; cathode band marked | Requires correct orientation on PCB; cannot protect AC or floating nodes without external diode pairing | Select only for DC rails with known polarity and no reverse-bias risk |
Compared with SMBJ110CA and P6KE110A, P6KE110CA-T provides proven axial-leaded mechanical robustness and bidirectional symmetry - critical for retrofitting legacy systems and protecting undefined-polarity interfaces without redesign.

FAQ
Is P6KE110CA-T still in active production?
No - Diodes Incorporated has officially discontinued the P6KE110CA-T (Document DS21502 Rev. 20-4 states "OBSOLETE – PART DISCONTINUED"). Aetrix Electronics maintains limited legacy stock and supports last-time buys with full traceability and extended lifecycle coordination for ongoing production programs.
What is the difference between P6KE110CA-T and P6KE110A-T?
P6KE110CA-T is bidirectional (marked with "C"), conducting avalanche current in both polarities; P6KE110A-T is unidirectional, with a cathode band indicating polarity-sensitive placement. Their VRWM, VBR, and VC values are identical, but P6KE110A-T cannot protect AC or floating nodes without additional components.
Can P6KE110CA-T be used in automotive applications?
While P6KE110CA-T meets AEC-Q200 passive component stress test requirements in practice, it is not formally AEC-Q200 qualified. For automotive production, Diodes recommends contacting their sales team for PPAP-capable, IATF 16949-manufactured alternatives with full qualification documentation.
What is the recommended PCB layout for optimal thermal performance?
Mount P6KE110CA-T with ≥9.5mm lead length and connect each lead to ≥40mm² copper land area to achieve the specified RθJA of 75°C/W. Avoid narrow traces; use thermal vias under pads if using hybrid through-hole/SMT layouts, and maintain ≥2mm clearance from heat sources.
