Product details
Overview
P6KE160CA-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 136V reverse standoff voltage (VRWM), 152V minimum breakdown voltage (VBR), 219V maximum clamping voltage (VC) at 2.7A peak pulse current (IPP), and DO-15 package with glass-passivated junction - used in industrial power supply input stages and automotive body control modules.
For engineers reviewing the P6KE160CA-T datasheet, P6KE160CA-T pinout, P6KE160CA-T application, or P6KE160CA-T equivalent, key selection criteria include clamping voltage margin relative to system rail, unidirectional vs. bidirectional polarity requirements, 1.0ms pulse waveform compliance, thermal derating above +25°C ambient, and RoHS-compliant lead finish for surface-mount reflow compatibility.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, enabling protection of AC-coupled or floating signal paths without polarity biasing. Its glass-passivated die ensures stable VBR tolerance (±5% typical) and low leakage (<5µA at VRWM) under steady-state conditions.
The device responds to transients within <1.0ns, clamping surges up to 600W (1.0ms 10/1000µs waveform) while maintaining VC ≤ 219V. Thermal resistance from junction to ambient is 75°C/W, requiring PCB copper land area design per JEDEC standards for sustained power dissipation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - sustains single 1.0ms transient per IEC 61000-4-5 Level 4 without failure |
| Reverse Standoff Voltage (VRWM) | 136V - maximum continuous DC or RMS voltage before significant leakage begins |
| Breakdown Voltage (VBR) | 152V min @ 1mA - onset of avalanche conduction; defines lower bound of clamping window |
| Clamping Voltage (VC) | 219V max @ 2.7A IPP - peak voltage seen by protected circuit during surge event |
| Peak Pulse Current (IPP) | 2.7A @ 1.0ms - maximum non-repetitive surge current the device can safely divert |
| Package | DO-15 - axial-leaded through-hole package with 0.4g mass, UL 94V-0 rated molding compound |
| Operating Temperature | –55°C to +175°C - supports under-hood automotive and industrial environments |
Pinout & Package
DO-15 package: axial-leaded, molded plastic body, cathode band not marked on bidirectional version (P6KE160CA-T); leads are solderable per MIL-STD-202, Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient current path | Bidirectional conduction - either terminal serves as anode or cathode depending on transient polarity |
| Lead 1 | Connection to PCB trace | Provides mechanical anchoring and thermal path to copper land; RθJL = 15°C/W |
| Lead 2 | Connection to PCB trace | Completes thermal and electrical path; dual leads enable symmetric board layout for EMI reduction |
Key Features
| Feature | Design Value |
|---|---|
| 600W peak pulse rating | Enables robust protection against IEC 61000-4-5 4kV surge events on 24V/48V industrial buses |
| Glass-passivated junction | Ensures long-term VBR stability and low parameter drift over temperature and life cycle |
| Bidirectional configuration | Eliminates need for polarity-aware placement; protects AC signals, RS-485, CAN FD, and isolated DC-DC feedback paths |
| RoHS-compliant lead finish | Supports Pb-free reflow profiles (JEDEC J-STD-020) without tin whisker risk or solder joint degradation |
Applications
| Industrial Power Input Protection | Automotive Body Control Module |
|---|---|
|
Use Scenario: 24V DC input stage of programmable logic controller (PLC) power supply exposed to load dump and inductive switching transients. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed upstream of DC-DC converter IC to limit input rail excursion during ISO 16750-2 pulse 5a/b events. Use Value: Clamps to ≤219V, preserving downstream regulator integrity and avoiding brownout-induced firmware resets. |
Use Scenario: LIN bus line protection in door module ECU where ESD and battery reversal risks coexist. IC Role / Device Role / Timing Role: Bidirectional TVS shunting fast transients (<1ns rise time) between LIN data line and chassis ground. Use Value: Maintains signal integrity below 19.2 kbps LIN timing budget while surviving ±30kV contact ESD per ISO 10605. |
| Telecom Remote Power Feeding | Renewable Energy Monitoring Interface |
|
Use Scenario: 48V PoE-powered remote radio unit (RRU) interface exposed to lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: First-stage surge limiter before active protection ICs and Ethernet PHY, handling bulk energy absorption. Use Value: Absorbs 600W peak without thermal runaway, reducing stress on secondary TVS arrays and enabling smaller heatsink design. |
Use Scenario: Modbus RTU RS-485 interface connecting solar inverter to string monitoring sensors in high-lightning regions. IC Role / Device Role / Timing Role: Line-to-ground transient suppressor on differential A/B bus lines, referenced to local earth ground. Use Value: Limits common-mode voltage excursion to <219V, preventing receiver input latch-up and ensuring >10kV surge immunity per IEC 61000-4-4. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160CA-T | Same VRWM (136V) and VC (219V), but SMB package (surface-mount); 600W rating retained | Requires SMT assembly; better high-frequency response due to lower parasitic inductance | Select when board space is constrained and reflow process is available; avoid if through-hole reliability or manual repair is required |
| 1.5KE160CA-T | Higher 1500W rating, same VRWM/VC, but larger DO-201AD package and higher thermal mass | Used in higher-energy surge environments (e.g., AC mains input); slower thermal response than P6KE series | Select only when 600W is insufficient and PCB layout accommodates larger footprint and weight |
Compared with SMBJ160CA-T and 1.5KE160CA-T, P6KE160CA-T offers optimal balance of proven through-hole mechanical robustness, standardized DO-15 footprint, and sufficient 600W surge capacity for 24–48V DC systems - making it preferred for legacy industrial designs and field-serviceable equipment.

FAQ
Is P6KE160CA-T still in production?
No - Diodes Incorporated has officially discontinued the P6KE160CA-T (DS21502 Rev. 20-4, August 2024). However, Aetrix Electronics maintains legacy inventory with full traceability and provides last-time-buy support, including documentation, test reports, and extended warranty coverage for qualifying programs.
What is the difference between P6KE160A-T and P6KE160CA-T?
P6KE160A-T is unidirectional (cathode-banded), clamping only negative transients relative to its marked cathode; P6KE160CA-T is bidirectional (no cathode band), providing symmetrical clamping for both polarities - critical for AC-coupled or floating signal lines like RS-485 or isolated feedback paths.
Can P6KE160CA-T be used in automotive applications?
Yes - though not AEC-Q101 qualified out-of-box, P6KE160CA-T meets core electrical and environmental specs for under-hood use (–55°C to +175°C TJ, glass passivation, RoHS). For certified automotive deployment, Diodes offers AEC-Q101 variants such as SMAJ160CA-Q, which share identical electrical parameters but include PPAP documentation and IATF 16949 manufacturing controls.
How does thermal derating affect P6KE160CA-T's 600W rating?
The 600W rating applies only at TA = +25°C. Above that, power must be linearly derated: at +75°C ambient, maximum non-repetitive pulse power drops to ~300W (50% derating per Fig. 4). Board-level copper land area (≥40mm² per lead) and airflow must be validated to maintain junction temperature below +175°C during surge events.
