Product details
Overview
P6KE200AH from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power lines and signal paths. It features a 200V nominal breakdown voltage (VBR min/max: 180V–220V), 162V stand-off voltage (VWM), clamps to ≤274V at 2.2A peak surge current, and operates across –55°C to +175°C junction temperature range.
For engineers reviewing the P6KE200AH datasheet, P6KE200AH pinout, P6KE200AH application, or P6KE200AH equivalent, this device is selected for automotive-grade ESD/EMI hardening of 24V/48V industrial power rails, battery management inputs, and CAN/LIN bus protection where AEC-Q101 qualification, low leakage (<1μA @ 171V), and fast clamping (<1.0ps response) are critical.
Technical Context
The P6KE200AH implements a silicon avalanche diode structure optimized for unidirectional clamping with low dynamic impedance and minimal capacitance. Its DO-204AC (DO-15) package supports lead-free soldering per J-STD-002 and meets UL 94V-0 flammability rating.
It delivers 600W non-repetitive peak pulse power at the standard 10/1000μs waveform, with thermal derating above 25°C ambient per Fig.2 and junction temperature limited to 175°C. Polarity is marked by cathode band; reverse leakage remains under 1μA at 171V (10% above VWM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 171 V - Maximum continuous reverse operating voltage before significant leakage begins; defines safe DC bias margin for 24V/48V systems. |
| VBR (min/max) | 180 V / 220 V - Breakdown occurs within this range at 1 mA test current; ensures predictable clamping onset across process variation. |
| VC @ IPPM | 274 V - Clamped voltage at 2.2 A peak surge current; determines maximum stress imposed on downstream circuitry during transients. |
| PPK | 600 W - Peak pulse power handling at 10/1000μs waveform; enables robust protection against ISO 7637-2 Pulse 1/2a/5a surges. |
| TJ max | +175 °C - Maximum junction temperature; supports operation in under-hood automotive and high-ambient industrial environments. |
| IR @ VWM | <1 μA - Reverse leakage at rated stand-off voltage; minimizes standby power loss and avoids false triggering in high-impedance sensing circuits. |
| Package | DO-204AC (DO-15) - Industry-standard axial-leaded package with 0.400 g mass; compatible with legacy through-hole assembly and automated tape-and-reel feeding (3500/reel). |
Pinout & Package
DO-204AC (DO-15) axial-leaded package with cathode band marking. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction path | Connected to system ground or lower-potential rail; conducts surge current to reference during overvoltage events. |
| Cathode | Reverse-biased clamping node | Connected to protected line (e.g., 24V supply); avalanche breakdown initiates when voltage exceeds VBR, shunting energy to ground. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control, body electronics, and ADAS power domains. |
| 600W surge capability | Withstands ISO 7637-2 Pulse 5a (500V/2Ω/50ms) without degradation when properly heatsinked. |
| Clamping voltage ≤274V | Ensures protected ICs (e.g., CAN transceivers, microcontrollers) remain below absolute maximum ratings during 2.2A transients. |
| Response time <1.0ps | Activates faster than most semiconductor switching events, preventing voltage overshoot from reaching sensitive nodes. |
| UL Recognized #E-326243 | Meets safety requirements for end-equipment certification in industrial and transportation equipment. |
Applications
| Automotive Power Rail Protection | Industrial 48V DC Distribution |
|---|---|

IC Role / Device Role / Timing Role: Low-capacitance unidirectional clamp referenced to common-mode ground, placed after primary common-mode choke. Use Value: Fast <1.0ps response prevents bit errors during EFT bursts (IEC 61000-4-4), while 274V clamping protects TJA1042/TJA1055 inputs. | Use Scenario: Front-end protection of 48V telecom rectifier outputs exposed to lightning-induced surges on outdoor plant wiring. IC Role / Device Role / Timing Role: Primary overvoltage clamp on -48V DC feed before DC/DC converters and hot-swap controllers. Use Value: 600W rating handles 10/1000μs lightning waveforms (IEC 61000-4-5 Level 4), reducing need for multi-stage protection networks. |
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 nominal, but SMB package (surface-mount); 600W rating; slightly higher VC (288V @ 2.1A). | Requires PCB rework for SMT layout; better suited for space-constrained designs with automated assembly. | Select SMBJ200A when board real estate is limited and reflow compatibility is required over through-hole reliability. |
| 1.5KE200A | Same DO-204AC package and 200V rating, but 1500W rating; higher IPP (10.3A); larger package volume (DO-201AD). | Overqualified for 600W needs; introduces unnecessary thermal mass and cost in low-energy surge environments. | Choose 1.5KE200A only if legacy 1500W compliance (e.g., MIL-STD-1275) is mandated and footprint change is acceptable. |
Compared with SMBJ200A and 1.5KE200A, the P6KE200AH offers optimal balance of AEC-Q101 qualification, axial-leaded mechanical robustness, and precise 600W surge handling-making it ideal for automotive and industrial through-hole power rail protection where qualification and assembly continuity matter.

FAQ
What does the "H" suffix in P6KE200AH signify?
The "H" suffix in P6KE200AH indicates AEC-Q101 qualification, confirming that the device has passed stress tests for automotive-grade reliability-including temperature cycling, humidity bias HAST, and ESD robustness. This makes P6KE200AH suitable for under-hood and body-control module applications where failure modes must be rigorously controlled. The qualification applies specifically to the P6KE200AH variant, not generic P6KE200.
How does P6KE200AH differ from the non-AEC-Q101 P6KE200A?
P6KE200AH differs from P6KE200A primarily in its AEC-Q101 qualification status, extended temperature validation, and enhanced process controls for automotive use. Both share identical electrical specs (VWM = 171 V, VC = 274 V @ 2.2 A), DO-204AC packaging, and 600W rating-but only P6KE200AH carries the formal automotive qualification required for Tier 1 supplier BOMs.
Can P6KE200AH be used in bidirectional configurations?
No, P6KE200AH is a unidirectional TVS diode and must not be used for bidirectional protection. Its cathode band marking and internal structure are optimized for positive-going transients only. For bidirectional applications (e.g., AC lines or differential buses), use P6KE200CA or equivalent bipolar variants-P6KE200AH will not clamp negative excursions and may fail catastrophically if reverse-biased beyond its 171V VWM rating.
What is the maximum allowable mounting pad size for P6KE200AH per thermal derating guidelines?
Per the datasheet's Absolute Maximum Ratings note (2), P6KE200AH's steady-state power dissipation (PD = 5 W) is specified with 0.375" (9.5 mm) lead lengths mounted on 5 × 5 mm copper pads per terminal. Exceeding this pad area does not increase PD rating; thermal performance depends on lead length and copper area per the defined test condition-not arbitrary PCB layout scaling.
Is P6KE200AH RoHS and halogen-free compliant?
Yes, P6KE200AH is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound meets UL 94V-0 flammability rating, and terminals are pure tin plated-ensuring compatibility with lead-free soldering processes and environmental compliance for export to EU, China, and other regulated markets. This is explicitly stated in the "Features" section of the official Taiwan Semiconductor documentation.
