Product details
Overview
P6KE200H from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power rails and signal lines. It features a 200V nominal breakdown voltage (VBR min/max = 180–220V), 162V stand-off voltage (VWM), clamps to ≤287V at 2.1A peak pulse current, and delivers sub-nanosecond response (<1.0ps from 0V to VBR). It is AEC-Q101 qualified and housed in a DO-204AC (DO-15) package for automotive front-end power protection.
For engineers reviewing the P6KE200H datasheet, P6KE200H pinout, P6KE200H application, or P6KE200H equivalent, key selection criteria include its 200V standoff rating, 287V clamping voltage at 2.1A, AEC-Q101 qualification, DO-15 mechanical compatibility, and suitability for 12/24V automotive power rail transients per ISO 7637-2 and IEC 61000-4-5.
Technical Context
The P6KE200H operates as a unidirectional avalanche diode with precise silicon junction design enabling fast turn-on under transient overvoltage. Its low dynamic impedance ensures stable clamping during 10/1000μs surges, while its 175°C maximum junction temperature supports operation in under-hood automotive environments.
It complies with ANSI/IEEE C62.35 for surge ratings and exhibits <1μA reverse leakage above 10V. The device is not bidirectional - polarity is marked on the cathode band, and forward surge capability (IFSM = 100A, 8.3ms half-sine) applies only in forward conduction mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 162 V - Maximum continuous DC or RMS voltage the device blocks without clamping; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 180–220 V at 1 mA - Voltage range at which avalanche conduction begins; guarantees reliable triggering across process variation. |
| VC @ IPPM (Clamping Voltage) | ≤287 V at 2.1 A - Peak voltage seen by protected circuit during 10/1000μs surge; determines downstream component stress level. |
| PPK (Peak Pulse Power) | 600 W - Maximum non-repetitive surge energy absorption capability per 10/1000μs waveform; defines single-event robustness. |
| IR @ VWM (Reverse Leakage) | <1 μA - Negligible standby current at rated standoff; avoids system power loss or false triggering in high-impedance circuits. |
| TJ max | 175 °C - Maximum junction temperature; enables use in engine control units and other high-ambient automotive locations. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD; required for powertrain and body electronics. |
Pinout & Package
Package: DO-204AC (DO-15), axial leaded, epoxy-molded case meeting UL 94V-0 flammability rating. Cathode indicated by band marking; leads are pure tin-plated and solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path); conducts during forward surge events (IFSM = 100 A). |
| Cathode | Avalanche clamping terminal | Connected to protected line (e.g., 24V rail); initiates avalanche breakdown when reverse voltage exceeds VBR, shunting surge to ground. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive powertrain and chassis applications requiring extended temperature cycling, high-temperature reverse bias, and mechanical shock resistance. |
| 600W 10/1000μs surge rating | Withstands single high-energy transients such as load dump (ISO 7637-2 Pulse 5a) without degradation or failure. |
| Sub-1ps response time (0V → VBR) | Activates before sensitive ICs experience overvoltage stress, protecting microcontrollers and CAN transceivers from ESD and EFT. |
| Low dynamic impedance | Maintains tight clamping voltage across varying surge currents, ensuring predictable protection margin for downstream components. |
| RoHS & halogen-free compliance | Meets IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for environmentally constrained automotive and industrial production. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200A | Same 200V VBR range but SMB package (surface-mount); 600W rating; slightly higher clamping (298V @ 2.1A). | Requires PCB rework for SMT layout; better suited for space-constrained board-level designs vs. through-hole P6KE200H. | Select SMBJ200A when automated assembly and smaller footprint are prioritized over manual repairability or high-temperature lead soldering. |
| 1.5KE200A | Same DO-15 package and 200V rating, but 1.5kW peak power (10/1000μs); larger die; higher thermal mass; clamps at 298V @ 7.2A. | Over-spec'd for 600W requirements; introduces unnecessary cost and board area unless legacy 1.5kW design reuse is needed. | Choose 1.5KE200A only if existing 1.5kW surge test compliance must be retained; otherwise P6KE200H offers optimal cost/performance for 600W-class protection. |
Compared with SMBJ200A and 1.5KE200A, P6KE200H delivers AEC-Q101 qualification in a proven through-hole DO-15 package with tighter clamping (287V), making it the preferred choice for new automotive and industrial designs requiring verified reliability and ease of prototyping.

FAQ
What is the clamping voltage of P6KE200H at its rated peak pulse current?
The P6KE200H clamps to a maximum of 287 V when subjected to its specified peak pulse current of 2.1 A under the standard 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during surge events. The P6KE200H maintains this clamping performance consistently across its qualified temperature range (−55°C to +175°C).
Is P6KE200H bidirectional or unidirectional?
P6KE200H is a unidirectional TVS diode, indicated by its cathode band marking and specified electrical characteristics for reverse-biased avalanche operation. It does not provide symmetrical clamping in both directions. For bidirectional protection at 200V, a P6KE200CA variant would be required - but that part is not offered in the AEC-Q101-qualified "H" suffix version. The P6KE200H is intended for DC rail protection where polarity is fixed.
Does P6KE200H meet automotive qualification standards?
Yes, P6KE200H is explicitly AEC-Q101 qualified, as confirmed in the ordering information and features list. This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD (HBM ≥8 kV), validating its suitability for automotive powertrain, body control, and infotainment systems. The "H" suffix in P6KE200H denotes this certified automotive grade.
What is the maximum steady-state power dissipation for P6KE200H at 75°C ambient?
The P6KE200H has a steady-state power dissipation (PD) rating of 5 W when mounted on 5 × 5 mm copper pads per lead at TA = 75°C. This derated value reflects thermal limits under continuous DC reverse bias near VWM (162 V), though typical operation remains well below this due to low leakage (<1 μA). The P6KE200H is not intended for sustained power dissipation - its design purpose is transient suppression, not steady-state regulation.
Can P6KE200H replace P6KE200 in an existing design?
Yes, P6KE200H is a direct replacement for P6KE200 with identical electrical specifications and DO-15 packaging, plus added AEC-Q101 qualification. The "H" suffix adds automotive reliability validation without altering VWM, VBR, VC, or surge ratings. No PCB or schematic changes are needed; the P6KE200H enhances long-term field reliability in automotive or industrial deployments where qualification traceability is required.
