Product details
Overview
P6KE200CAH from Taiwan Semiconductor is a bidirectional 600W transient voltage suppressor (TVS) diode designed for high-energy surge protection in automotive and industrial power rails. It features a 200V nominal breakdown voltage (VBR min/max: 180–220V), 162V standoff voltage (VWM), clamps to ≤287V at 2.1A peak surge current, and uses DO-204AC (DO-15) package with AEC-Q101 qualification for under-hood applications.
For engineers reviewing the P6KE200CAH datasheet, P6KE200CAH pinout, P6KE200CAH application, or P6KE200CAH equivalent, this part delivers verified bidirectional clamping performance, low dynamic impedance, sub-5ns response time, and UL recognition - critical for EFT/ESD immunity design in 12V/24V/48V systems.
Technical Context
The P6KE200CAH implements a silicon avalanche junction structure optimized for fast transient suppression in both polarities. Its bidirectional configuration enables symmetric clamping without external polarity management, and its 10/1000μs waveform rating of 600W supports IEC 61000-4-5 Level 4 surge compliance.
With a maximum junction temperature of +175°C and thermal derating per Fig.2, it sustains repeated surges in high-ambient environments. The device exhibits <1μA reverse leakage at 162V and a VBR temperature coefficient of 0.108%/°C, enabling stable operation across automotive temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 162 V - Maximum continuous reverse operating voltage before significant leakage; defines safe DC bias margin. |
| VBR (min/max) | 180–220 V - Breakdown occurs within this range at 1 mA test current; ensures predictable clamping onset. |
| VC @ IPP | 287 V @ 2.1 A - Clamped voltage during 10/1000μs surge; determines protected circuit's maximum stress level. |
| PPK | 600 W - Peak pulse power handling per 10/1000μs waveform; validates robustness against lightning-induced transients. |
| IR @ VWM | <1 μA - Reverse leakage at rated standoff voltage; minimizes standby power loss in always-on systems. |
| TJ max | +175 °C - Maximum junction temperature; supports placement near heat sources in engine control units. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing. |
Pinout & Package
Package: DO-204AC (DO-15), axial leaded, epoxy-molded case with UL 94V-0 flammability rating and pure tin-plated leads compliant with J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (cathode band absent) | Non-polarized terminal | Bidirectional symmetry - either end connects to line or return; no polarity marking required. |
| Cathode (cathode band absent) | Non-polarized terminal | Identical to anode in CA configuration; terminals interchangeable for AC-coupled or floating-rail protection. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC lines or differential buses without polarity constraints. |
| Fast response time | Typically <5 ns from 0 V to VBR - limits voltage overshoot before clamping engages. |
| Low dynamic impedance | Ensures minimal voltage rise under surge current, improving clamping precision vs. MOVs. |
| UL 94V-0 molding compound | Meets flame-retardant requirements for enclosed automotive and industrial enclosures. |
| JESD201 Class 2 whisker resistance | Prevents tin whisker growth in long-life deployments, critical for safety-critical ECUs. |
Applications
| Automotive Power Rail Protection | Industrial PLC Input Protection |
|---|---|
Use Scenario: Protecting 24V CAN bus power supply against load dump and alternator transients. IC Role / Device Role / Timing Role: Primary surge clamp on main VBAT rail upstream of DC-DC converters and CAN transceivers. Use Value: Limits transient voltage to ≤287V, preventing damage to 36V-rated downstream regulators and communication ICs. |
Use Scenario: Shielding 24V digital input modules from inductive kickback in factory automation solenoids. IC Role / Device Role / Timing Role: Front-end TVS on isolated optocoupler inputs to absorb repetitive 10/1000μs surges. Use Value: Withstands >100,000 surges at 2.1A due to low degradation rate, extending field service life. |
| LED Driver Overvoltage Clamp | Smart Meter AC Mains Interface |
Use Scenario: Safeguarding constant-current LED drivers in street lighting against lightning-induced line surges. IC Role / Device Role / Timing Role: Parallel-connected TVS across driver output to clamp overvoltage before LED string failure. Use Value: 600W rating handles multi-kV induced surges; 175°C rating allows mounting near thermally stressed driver ICs. |
Use Scenario: Protecting metering IC analog front-ends connected to 230VAC via resistive divider networks. IC Role / Device Role / Timing Role: Secondary-level clamp after MOV primary stage to limit let-through voltage to <300V. Use Value: Bidirectional symmetry matches AC waveform polarity reversal; low IR avoids measurement drift in high-impedance dividers. |
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 | Same 200V VBR range but SMB package (surface-mount); lower 600W rating tested at 10/1000μs; slightly higher VC (290V). | Preferred for space-constrained PCBs; requires reflow-compatible layout; not axial-lead drop-in. | Select when automated assembly and board density outweigh lead-forming flexibility. |
| 1.5KE200CA | Same DO-15 package and 200V rating but 1500W rating; larger die size; higher clamping voltage (324V) and leakage (5μA). | Better for infrequent, high-energy surges (e.g., direct lightning coupling); less suitable for repetitive EFT. | Choose only if system-level testing confirms 324V clamping is acceptable for protected ICs. |
Compared with SMBJ200CA and 1.5KE200CA, the P6KE200CAH offers optimal balance of AEC-Q101 qualification, axial-lead serviceability, 287V clamping, and 1μA leakage - making it the preferred choice for production automotive and industrial control modules requiring validated reliability and ease of manual repair.

FAQ
What does the "CA" suffix indicate in P6KE200CAH?
The "CA" suffix in P6KE200CAH denotes bidirectional configuration - meaning the device provides symmetrical clamping in both forward and reverse directions, eliminating the need for polarity-aware placement on AC-coupled or floating circuits. This distinguishes it from unidirectional "C" variants and ensures consistent protection regardless of voltage polarity swing.
Is P6KE200CAH suitable for IEC 61000-4-5 surge testing?
Yes, P6KE200CAH is rated for 600W peak pulse power at the 10/1000μs waveform defined in IEC 61000-4-5, making it appropriate for Level 3 and Level 4 surge immunity testing in 24V and 48V systems. Its 287V clamping voltage at 2.1A ensures protected circuitry remains below typical 36V or 40V IC absolute maximum ratings during standardized surge events.
How does the "H" suffix affect P6KE200CAH qualification status?
The "H" suffix in P6KE200CAH certifies full AEC-Q101 qualification - including stress tests for temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge - confirming suitability for automotive under-hood applications. This is explicitly documented in TSC's ordering information and supersedes generic "AEC-Q101 available" statements for non-H variants.
What is the maximum allowable ambient temperature for continuous operation of P6KE200CAH?
P6KE200CAH supports continuous operation up to +75°C ambient when mounted on 5×5 mm copper pads per terminal, delivering 5W steady-state power dissipation. Above 75°C, derating follows Fig.2 in the datasheet - e.g., at +100°C ambient, maximum power drops to ~3.5W - ensuring junction temperature stays within the rated −55°C to +175°C range.
Can P6KE200CAH replace P6KE200A in an existing design?
No - P6KE200CAH is bidirectional (CA), while P6KE200A is unidirectional (A). Substituting P6KE200CAH for P6KE200A introduces a cathode band ambiguity and may compromise clamping behavior in DC-biased circuits. For unidirectional replacement, use P6KE200CH; for bidirectional upgrade, verify system polarity tolerance and update layout to omit cathode orientation constraints.
