Taiwan Semiconductor Corporation P6KE130

Overview

P6KE130 from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a 130V nominal breakdown voltage (VBR min/max: 117V–143V), 105V standoff voltage (VWM), clamps to ≤187V at 3.3A peak surge current, and delivers sub-nanosecond response (<1.0ps) to ESD and lightning-induced transients - deployed in automotive body control modules and industrial PLC I/O protection.

For engineers reviewing the P6KE130 datasheet, P6KE130 pinout, P6KE130 application, or P6KE130 equivalent, key selection criteria include its DO-204AC (DO-15) axial package, AEC-Q101 qualification (P6KE130H variant), 175°C max junction temperature, and compliance with ANSI/IEEE C62.35 for surge immunity design in 12/24V systems.

Technical Context

The P6KE130 operates as a silicon avalanche diode with unidirectional polarity, leveraging controlled reverse-biased breakdown to clamp transient voltages above VWM while maintaining low leakage (<1μA at 105V). Its 10/1000μs waveform surge rating of 600W enables robust protection against IEC 61000-4-5 Level 4 surges (4kV line-to-earth).

Thermal derating begins above 25°C ambient per Fig.2, with full power capability maintained up to 75°C when mounted on 5×5 mm copper pads. The device exhibits a +0.107%/°C temperature coefficient of VBR, ensuring predictable voltage drift across automotive-grade operating ranges (−55°C to +175°C).

FAQ

What is the maximum clamping voltage of the P6KE130 under surge conditions?

The P6KE130 clamps to a maximum of 187 V when subjected to its rated peak pulse current of 3.3 A (10/1000μs waveform). This value is measured per ANSI/IEEE C62.35 and represents the upper limit of voltage imposed on protected circuitry during transient events - critical for ensuring downstream ICs remain within absolute maximum ratings. The P6KE130 achieves this with low dynamic impedance and fast avalanche response.

Is the P6KE130 suitable for automotive applications?

Yes, the P6KE130H variant is AEC-Q101 qualified and explicitly listed in TSC's ordering matrix for automotive use. While the base P6KE130 is not qualified, the H-suffix version undergoes stress testing for temperature cycling, humidity bias, and mechanical shock per automotive standards. For automotive designs, specify P6KE130H to ensure compliance - the P6KE130 itself is intended for industrial and commercial applications.

What is the standoff voltage (VWM) rating of the P6KE130, and why does it matter?

The P6KE130 has a standoff voltage (VWM) of 105 V, meaning it remains non-conductive up to this DC or RMS voltage level. This parameter defines the maximum continuous operating voltage of the protected line and must be selected ≥10–20% above the system's normal operating voltage to avoid false triggering. For a 24V automotive system, P6KE130 provides ample margin; for 48V systems, a higher-voltage variant like P6KE150 would be appropriate.

How does the P6KE130 compare to the P6KE130A in terms of electrical performance?

The P6KE130A offers tighter VBR tolerance (124–137 V vs. 117–143 V for P6KE130) and higher VWM (111 V vs. 105 V), resulting in improved noise immunity and reduced risk of nuisance conduction. Its clamping voltage is also lower (179 V vs. 187 V at 3.5A), enhancing protection margin. Both share identical package, surge rating, and thermal specs - the A-suffix denotes enhanced parameter distribution for precision-critical applications.

Can the P6KE130 be used in bidirectional configurations?

No - the P6KE130 is a unidirectional TVS diode, intended only for DC circuits with defined polarity. Bidirectional protection requires a CA-suffix part (e.g., P6KE130CA) or dual-diode configuration. Using P6KE130 in AC or bipolar signal paths risks forward conduction during negative half-cycles, leading to overheating or failure. Always verify polarity alignment during placement; cathode band must face the protected line side.
