Product details
Overview
P6KE200CA-T from Diodes Incorporated is a bidirectional 600W transient voltage suppressor (TVS) diode in DO-15 package, designed for overvoltage protection of DC power lines and signal interfaces. It features a 171V reverse standoff voltage (VRWM), 190V minimum breakdown voltage (VBR), 274V maximum clamping voltage (VC) at 2.2A peak pulse current (IPP), and fast response time for ESD and surge suppression in industrial power supplies.
For engineers reviewing the P6KE200CA-T datasheet, P6KE200CA-T pinout, P6KE200CA-T application, or P6KE200CA-T equivalent, key selection criteria include clamping voltage margin relative to system rail, unidirectional vs. bidirectional polarity requirement, DO-15 thermal derating behavior, and compliance with IEC 61000-4-2/4-5 surge immunity standards.
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 junction ensures stable VBR and low leakage (<5 µA at VRWM) over temperature and lifetime.
The device sustains 600W peak pulse power (10/1000 µs waveform) with clamping performance validated at 2.2A IPP, and exhibits thermal resistance of 75°C/W (junction-to-ambient) when mounted on standard PCB land patterns - critical for sustained surge handling in compact layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W (10/1000 µs waveform); defines maximum transient energy absorption capability without failure |
| Reverse Standoff Voltage (VRWM) | 171V; maximum continuous DC or RMS voltage the device blocks before entering avalanche conduction |
| Breakdown Voltage (VBR) | 190V min @ 1mA; voltage at which avalanche conduction begins - sets lower bound of clamping onset |
| Clamping Voltage (VC) | 274V max @ 2.2A IPP; peak voltage seen by protected circuit during worst-case surge event |
| Peak Pulse Current (IPP) | 2.2A @ 10/1000 µs; maximum non-repetitive surge current the device safely clamps |
| Junction-to-Ambient RθJA | 75°C/W; determines temperature rise under steady-state power dissipation (5.0W max at TL = 75°C) |
| Package | DO-15; axial-leaded plastic package rated UL 94V-0, compatible with wave soldering and manual assembly |
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, and rated for 100A peak forward surge (8.3ms half-sine).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during positive transients | One end of symmetrical PN junction - identical electrical role as Cathode under reverse polarity |
| Cathode | Current entry point during negative transients | Other end of symmetrical PN junction - functionally interchangeable with Anode in bidirectional operation |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC lines or differential signals without external polarity control |
| Glass-passivated die | Ensures stable VBR tolerance (±5% typical), low IR drift, and long-term reliability under humidity/stress |
| 600W peak pulse rating | Supports Level 4 IEC 61000-4-5 (4kV line-earth surge) protection with adequate margin |
| RoHS-compliant lead finish | Lead-free plating meets EU RoHS 2 (2011/65/EU) and supports automated reflow/wave soldering |
Applications
| Industrial Power Input Protection | Automotive Body Control Module (BCM) |
|---|---|
Use Scenario: 24V DC input stage of programmable logic controller (PLC) exposed to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed upstream of DC-DC converter input filter. Use Value: Limits transient voltage to ≤274V, preventing damage to downstream 36V-rated input capacitors and controller ICs. |
Use Scenario: CAN bus power rail (VBAT) in BCM subjected to battery reversal and jump-start surges. IC Role / Device Role / Timing Role: Bidirectional TVS shunting both positive and negative transients on shared 12V supply net. Use Value: Clamps reverse surges to <–274V and positive surges to >+274V, protecting CAN transceivers and microcontroller LDOs. |
| AC-DC Adapter Secondary Side | Telecom Line Interface Protection |
Use Scenario: Output rectifier stage of 48V telecom adapter where output may experience backfeed or lightning-induced surges. IC Role / Device Role / Timing Role: Secondary-side TVS parallel to output capacitor, triggered within nanoseconds of overvoltage onset. Use Value: Maintains regulated 48V output integrity by clamping transients before they propagate to connected equipment. |
Use Scenario: Tip/ring line interface of VoIP gateway exposed to induced surges from nearby AC wiring or lightning coupling. IC Role / Device Role / Timing Role: Bidirectional protection element across differential analog line pair prior to codec input. Use Value: Preserves signal fidelity by limiting common-mode surge voltage to <±274V while adding <1pF capacitance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200CA | DO-214AA package; 600W rating; 171V VRWM; 274V VC @ 2.2A - identical electrical specs but surface-mount | Requires PCB redesign for SMT placement; better thermal performance due to lower RθJA (50°C/W) | Select when board space is constrained and reflow assembly is available. |
| 1.5KE200CA | DO-201AD package; 1500W rating; same 171V VRWM; 274V VC @ 5.5A - higher power, larger footprint | Supports higher-energy surges (e.g., IEC 61000-4-5 Level 5); requires larger copper area and lead spacing | Select when legacy through-hole compatibility is required and surge threat level exceeds 600W. |
Compared with SMBJ200CA and 1.5KE200CA, P6KE200CA-T offers identical clamping performance in a cost-optimized DO-15 axial package - ideal for manual assembly, field-replaceable modules, and designs prioritizing procurement continuity over ultra-high surge margin.

FAQ
Is P6KE200CA-T still in active production?
No - Diodes Incorporated has officially discontinued the P6KE200CA-T (document DS21502 Rev. 20-4 states "OBSOLETE – PART DISCONTINUED"). However, Aetrix Electronics maintains limited legacy stock with full traceability and supports last-time buys for ongoing production programs.
What is the difference between P6KE200A-T and P6KE200CA-T?
P6KE200A-T is unidirectional (cathode-banded), clamping only negative transients; P6KE200CA-T is bidirectional (no cathode band), providing symmetrical clamping for both polarities - critical for AC-coupled or floating circuits where polarity is undefined.
Can P6KE200CA-T be used in automotive applications?
While not AEC-Q200 qualified, P6KE200CA-T is widely deployed in non-safety-critical automotive subsystems (e.g., BCM, infotainment power rails). For AEC-Q200-compliant alternatives, Diodes recommends the AEC-Q200-qualified SMAJ200CA or SMCJ200CA series.
What is the maximum operating temperature for P6KE200CA-T?
The device operates from –55°C to +175°C junction temperature. At ambient temperatures above +25°C, pulse power must be derated per Figure 4 in DS21502 - e.g., at +85°C ambient, peak pulse power drops to ~420W for reliable operation.
