Taiwan Semiconductor Corporation P4KE200C

Overview

P4KE200C from Taiwan Semiconductor is a bidirectional transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power rails and signal lines. It features a 200V nominal standoff voltage, 287V maximum clamping voltage at 1.4A peak pulse current, 400W peak pulse power rating (10/1000μs), and DO-204AL (DO-41) axial package - deployed in automotive lighting control modules to absorb load-dump transients.

For engineers reviewing the P4KE200C datasheet, P4KE200C pinout, P4KE200C application, or P4KE200C equivalent, key selection criteria include bidirectional clamping symmetry, low leakage (<1μA at 162V), fast response (<5ns), AEC-Q101 qualification, and compatibility with 10/1000μs surge waveforms per IEC 61000-4-5.

Technical Context

The P4KE200C operates as a voltage-clamped crowbar device, entering avalanche breakdown symmetrically in both polarities when transient voltage exceeds its 180–220V breakdown range (VBR @ 1mA). Its low dynamic impedance ensures stable clamping during 10/1000μs surges up to 400W without thermal runaway.

Designed for unclamped inductive switching environments, it sustains 175°C junction temperature and exhibits a +0.108%/°C VBR temperature coefficient - enabling predictable performance across automotive under-hood temperature ranges (-55°C to +175°C).

FAQ

What is the clamping voltage of P4KE200C under a 10/1000μs surge?

The P4KE200C clamps to a maximum of 287 V when subjected to its rated 1.4 A peak pulse current (IPPM), corresponding to a 400W 10/1000μs waveform per ANSI/IEEE C62.35. This value is guaranteed across the full operating temperature range and represents the highest voltage seen by downstream circuitry during surge events. The P4KE200C maintains this clamping performance consistently due to its tightly controlled avalanche characteristics and low dynamic impedance.

Is P4KE200C unidirectional or bidirectional?

The P4KE200C is a bidirectional TVS diode, indicated by the "C" suffix per Taiwan Semiconductor's ordering convention. It provides symmetrical clamping in both polarities, with identical breakdown (180–220 V) and clamping (287 V) specifications regardless of voltage polarity. This makes the P4KE200C ideal for protecting AC-coupled signals, floating buses, or DC rails where reverse polarity risk exists - unlike unidirectional variants (e.g., P4KE200) which require correct orientation.

Does P4KE200C meet AEC-Q101 reliability standards?

Yes, the P4KE200C is AEC-Q101 qualified, as confirmed in the official Taiwan Semiconductor P4KE Series datasheet (Version N2104). This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD - validating its suitability for automotive powertrain, chassis, and body electronics. The P4KE200C's qualification applies specifically to the DO-204AL packaged variant and is documented under TSC's AEC-Q101 certification scope.

What is the maximum junction temperature rating for P4KE200C?

The P4KE200C has a maximum junction temperature (TJ max) rating of +175°C, enabling reliable operation in high-ambient environments such as engine compartments or enclosed industrial enclosures. This rating is supported by its DO-204AL package construction, UL 94V-0 molding compound, and thermal design validated per JEDEC standards. Derating curves in the P4KE200C datasheet define allowable power dissipation above 25°C ambient, ensuring safe thermal margins in real-world deployments.

How does P4KE200C compare to P4KE200A in terms of voltage tolerance?

The P4KE200C has a breakdown voltage range of 180–220 V (min/max) at 1 mA test current, while the P4KE200A variant tightens this to 190–210 V - reflecting a ±5% tolerance versus the standard ±10%. Both share identical clamping voltage (287 V), peak power (400 W), and package (DO-41), but the P4KE200A offers improved VBR consistency for applications demanding tighter voltage thresholds. The P4KE200C remains the default choice where cost and broad availability are prioritized over narrow VBR spread.
