What is the 1N6068A/TR?
The 1N6068A/TR is a Zener-type bidirectional TVS diode from Microchip Technology, designed for general-purpose transient voltage suppression. It delivers a peak pulse power rating of 1500W (1.5kW) per the 10/1000µs waveform, making it suitable for clamping high-energy surges on DC power rails or signal lines. The device is bidirectional with a single channel, meaning it clamps both positive and negative transients symmetrically — useful for AC-coupled or floating lines where polarity is not fixed.
Breakdown voltage (min) is 162V — this is the voltage at which the diode starts to conduct significantly. For a 145V reverse standoff voltage (working voltage), the 162V breakdown provides a reasonable margin before clamping begins, reducing leakage under normal operation. Maximum clamping voltage is 245V at a peak pulse current of 6.1A. This means that under a 1500W surge, the voltage across the device will not exceed 245V, protecting downstream components rated above that level. Operating temperature range spans -55°C to 175°C (junction), which covers military and industrial environments — avionics, downhole tools, outdoor telecom enclosures, and engine-bay electronics all fall within this envelope.
Lifecycle and sourcing posture
This means production is ongoing and the part is available through franchised distribution channels. Sourced per RFQ against your BOM quantity. The DO-13 metal can package offers robust thermal performance and is commonly used in high-reliability applications.
