Product details

Transient suppressor for 38.8 V rails

Its 1500 W peak pulse power rating handles surges up to 21.4 A before the clamp voltage reaches 70.1 V.

Clamp voltage and breakdown margin

Minimum breakdown voltage is 48.5 V, giving a guard band above the 38.8 V standoff. The 70.1 V maximum clamp at 21.4 A peak pulse current defines the voltage the protected circuit must survive. This is a bidirectional device — one channel clamps both polarities, simplifying board layout for AC-coupled or floating lines.

Microchip lists the 1N6159A as Active. The part is in the B, Axial through-hole case.

Frequently asked questions

Can I use the 1N6159A for automotive applications?

The operating temperature range (-55°C to 175°C) covers automotive under-hood and cabin environments, but the evidence does not list AEC-Q101 qualification. Verify with your quality team whether the part meets the required automotive grade for your specific application.
