Taiwan Semiconductor Corporation P6KE220AH

Overview

P6KE220AH 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 220V nominal breakdown voltage (VBR min/max: 198–242V), 175V stand-off voltage (VWM), clamps to ≤328V at 1.9A peak surge current, and operates across –55°C to +175°C junction temperature range. It is AEC-Q101 qualified and housed in DO-204AC (DO-15) package for automotive ECU input protection.

For engineers reviewing the P6KE220AH datasheet, P6KE220AH pinout, P6KE220AH application, or P6KE220AH equivalent, key selection criteria include its 600W 10/1000μs surge rating, low dynamic impedance, sub-1ps response time from 0V to VBR, <1μA leakage above 10V, and AEC-Q101 qualification for under-hood automotive use.

Technical Context

The P6KE220AH employs a silicon avalanche diode structure optimized for fast clamping of high-voltage transients. Its unidirectional configuration provides polarity-sensitive protection with cathode-band marking, and it delivers stable breakdown behavior over temperature with a VBR temperature coefficient of 0.108%/°C.

It meets ANSI/IEEE C62.35 standards for transient suppression and is rated for non-repetitive 600W peak pulse power at 10/1000μs waveform. The device supports steady-state power dissipation of 5W at 75°C ambient when mounted on 5×5 mm copper pads, and withstands 100A forward surge current (8.3ms half-sine) - though this applies only to unidirectional variants like P6KE220AH.

FAQ

What is the clamping voltage of P6KE220AH and how is it measured?

The P6KE220AH has a maximum clamping voltage (V_C) of 328 V at 1.9 A peak pulse current (I_PP), tested with a 10/1000 μs double-exponential surge waveform. This value represents the upper limit of voltage the device allows across its terminals during a standardized transient event, ensuring downstream components remain within safe operating limits. The P6KE220AH achieves this clamping performance while maintaining low dynamic impedance and fast response.

Is P6KE220AH suitable for bidirectional surge protection?

No, P6KE220AH is a unidirectional TVS diode, intended for polarity-specific protection where the cathode connects to the higher-potential line. For bidirectional applications, the P6KE220A variant (not P6KE220AH) is specified - it uses a symmetrical breakdown structure and lacks polarity marking. Using P6KE220AH in reverse-biased mode beyond its V_WM risks premature conduction or degradation. Always verify polarity alignment in circuit design for P6KE220AH.

Does P6KE220AH meet automotive qualification standards?

Yes, P6KE220AH is explicitly AEC-Q101 qualified, as confirmed by Taiwan Semiconductor's ordering code suffix "H" and documentation. This qualification covers stress tests including temperature cycling, high-temperature operating life, and mechanical shock - validating its suitability for under-hood and chassis-mounted automotive electronics. The "H" suffix distinguishes it from non-qualified variants like P6KE220A, making P6KE220AH appropriate for safety-critical vehicle subsystems.

What is the maximum operating temperature for P6KE220AH?

The P6KE220AH has a maximum junction temperature (T_J) of +175°C and a storage temperature range of –55°C to +175°C. Its DO-204AC (DO-15) package supports thermal dissipation sufficient for sustained operation in high-ambient environments such as engine compartments, provided PCB copper land patterns meet the 5×5 mm pad recommendation per terminal. Derating of peak pulse power applies above 25°C ambient per the published derating curve.

How does P6KE220AH compare to P6KE220A in terms of electrical performance?

P6KE220AH and P6KE220A share identical nominal voltage (220V), breakdown range (198–242V), clamping voltage (328V), and surge rating (600W). The key distinction is qualification: P6KE220AH carries AEC-Q101 certification and uses enhanced process controls, while P6KE220A is for general industrial use. Both use DO-204AC packaging, but only P6KE220AH guarantees automotive-grade reliability data and traceability - critical for P6KE220AH deployment in certified vehicle systems.
