Product details
Overview
P6KE200A-T from Diodes Incorporated is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary overvoltage protection in DC power lines and signal interfaces. It features a 171–210 V reverse standoff voltage range (VRWM), 274 V maximum clamping voltage at 2.2 A peak pulse current, and DO-15 glass-passivated package. Used in industrial power supplies and telecom line cards to absorb lightning-induced surges.
For engineers reviewing the P6KE200A-T datasheet, P6KE200A-T pinout, P6KE200A-T application, or P6KE200A-T equivalent, key selection criteria include clamping voltage margin relative to protected IC VCC rails, 1.0 ms pulse waveform compliance, thermal derating above +25°C ambient, and unidirectional polarity alignment with DC bias direction.
Technical Context
This TVS operates as a voltage-clamped shunt protector: under normal conditions it presents <5 µA leakage at 171 V; when transient voltage exceeds 190 V (min breakdown), it avalanches rapidly (<1 ns response) to clamp the line at ≤274 V. Its 600 W peak pulse rating applies to a single 1.0 ms 10/1000 µs waveform per IEC 61000-4-5.
The device uses a glass-passivated silicon junction for stable breakdown characteristics and long-term reliability. Thermal resistance from junction to ambient is 75 °C/W, requiring PCB copper land area (≥40 mm²) and lead length control (9.5 mm) to sustain 5.0 W steady-state dissipation at TL = +75°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W - Sustains one 1.0 ms 10/1000 µs surge without failure per IEC 61000-4-5 Level 4. |
| Reverse Standoff Voltage | 171–210 V - Maximum continuous DC or RMS voltage before significant leakage; sets minimum operating rail margin. |
| Breakdown Voltage | 190 V min @ 1 mA - Confirmed avalanche initiation point; ensures reliable turn-on before downstream IC damage. |
| Clamping Voltage | 274 V max @ 2.2 A - Actual voltage seen by protected circuit during surge; defines safe headroom for 240 VAC-derived rails. |
| Leakage Current | ≤5.0 µA @ 171 V - Negligible standby power loss and minimal impact on high-impedance sensing nodes. |
| Package | DO-15 - Axial-leaded plastic case rated UL 94V-0; enables manual soldering and wave-solder compatibility. |
Pinout & Package
DO-15 package: axial-leaded, molded plastic body with cathode band marking. Dimensions: length 25.4 mm (min), body diameter 5.5–7.62 mm, lead diameter 0.686–0.889 mm, lead spacing 2.6–3.6 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lowest potential node; defines unidirectional conduction path from cathode to anode during surge. |
| Cathode | High-side surge input terminal | Marked with band; connects to protected line; conducts avalanche current to anode when line voltage exceeds VRWM. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse rating | Enables robust protection against IEC 61000-4-5 4 kV/2 Ω surges on 240 VAC-derived DC buses. |
| Glass-passivated die construction | Ensures stable breakdown voltage over temperature (-55°C to +175°C) and long-term reliability in humid environments. |
| Fast response time (<1 ns) | Clamps transients before sensitive downstream components (e.g., MOSFET gate drivers, MCU I/O) experience overvoltage stress. |
| RoHS-compliant lead finish | Meets EU Directive 2011/65/EU with full exemption documentation; supports lead-free reflow and hand-soldering processes. |
Applications
| Industrial Power Supply Input Protection | Telecom Line Card Surge Suppression |
|---|---|
Use Scenario: 240 VAC rectified and filtered DC bus feeding isolated DC/DC converters in factory automation controllers. IC Role / Device Role / Timing Role: Unidirectional TVS placed between +BUS and GND to clamp lightning-induced common-mode surges entering via AC input. Use Value: Limits transient voltage to ≤274 V, preserving 400 V-rated bulk capacitors and preventing MOSFET avalanche failure in primary-side switches. |
Use Scenario: -48 VDC power feed to DSLAM line cards exposed to induced surges from nearby lightning strikes on telephone cables. IC Role / Device Role / Timing Role: Shunt protector on -48 V rail upstream of DC/DC regulators and line interface ICs. Use Value: Absorbs 600 W surge energy within 1.0 ms, maintaining rail integrity below -55 V to avoid regulator shutdown and data corruption. |
| Automotive Body Control Module (BCM) Power Input | Renewable Energy Inverter DC Link Protection |
Use Scenario: 12 V battery-fed BCM with CAN/LIN interfaces subject to load dump (ISO 7637-2 Pulse 5a) and jump-start transients. IC Role / Device Role / Timing Role: Primary clamping device on main VBAT input, coordinated with upstream fuse and secondary LC filtering. Use Value: Clamps 120 V transients to ≤274 V with 2.2 A peak current, allowing downstream LDOs and microcontrollers to remain operational. |
Use Scenario: 600 V DC link in solar string inverters where PV array surges couple into DC bus during grid faults or lightning events. IC Role / Device Role / Timing Role: Parallel-mounted TVS across DC+ and DC− near inverter bridge to limit overvoltage during fast-rising transients. Use Value: Provides 600 W pulse handling at 200 V nominal, enabling system-level coordination with MOVs and crowbar circuits for multi-stage protection. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200A-T | Same 200 V standoff, but SMB package (surface-mount); 600 W rating at 1.0 ms; lower RθJA (50 °C/W vs. 75 °C/W). | Requires PCB real estate for SMT placement; better thermal performance in compact layouts; no axial lead bending needed. | Select for automated assembly, space-constrained designs, or higher board density where DO-15 leads pose routing challenges. |
| P6KE200CA-T | Bidirectional version; identical VRWM (171–210 V), same clamping (274 V), but symmetrical breakdown in both polarities. | Used in AC-coupled or floating signal lines (e.g., RS-485, CAN bus) where polarity reversal or differential surges occur. | Select only when protecting bidirectional signals or AC-powered circuits; unidirectional P6KE200A-T is preferred for DC rails to avoid unnecessary leakage. |
Compared with SMBJ200A-T, P6KE200A-T offers easier manual prototyping and legacy through-hole compatibility but requires more board area and has higher thermal resistance; compared with P6KE200CA-T, it provides lower leakage and tighter clamping control in fixed-polarity DC systems.

FAQ
Is P6KE200A-T still in active production?
No - Diodes Incorporated has officially discontinued the P6KE200A-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 last-time buys and cross-reference alternatives.
What is the maximum clamping voltage for P6KE200A-T at 1.0 A surge current?
Per the datasheet's electrical characteristics table, the maximum clamping voltage VC is specified at IPP = 2.2 A (not 1.0 A). Extrapolation is not valid; actual clamping at 1.0 A would be lower than 274 V but is not characterized or guaranteed. Design must use the rated 2.2 A condition.
Can P6KE200A-T be used in place of a bidirectional TVS like P6KE200CA-T?
No - P6KE200A-T is unidirectional and will conduct continuously if reverse-biased beyond its breakdown voltage. Substituting it for P6KE200CA-T in AC or floating signal paths risks catastrophic failure, excessive leakage, or incorrect clamping behavior during negative transients.
What is the recommended PCB pad layout for DO-15 mounting to ensure thermal performance?
Diodes specifies a 40 mm² copper land area with 9.5 mm lead length for 5.0 W steady-state dissipation. Use ≥2 oz copper, thermal vias under pads, and minimize trace length between anode/cathode pads and ground/power planes to maintain RθJA ≤75 °C/W.
