Key Features
- 1500W peak pulse power dissipation capability providing robust transient overvoltage protection for sensitive electronics
- Bi-directional clamping in a 2-pin axial 1.5KE package enabling AC and bidirectional signal line protection
- Fast response time in sub-picosecond range clamping surge transients to protect downstream ICs and circuits
Applications
Vishay 1N6385-E3/54 is used on AC power lines and bidirectional signal buses where surge protection up to 1500W peak pulse power is required. Its bi-directional clamping characteristic makes it suitable for protecting RS-485, RS-422, and industrial I/O interfaces against ESD and lightning-induced transients. The axial through-hole package allows easy integration on power supply boards, motor drive inputs, and communication interface protection circuits.

Frequently Asked Questions
What peak power and clamping behavior does Vishay 1N6385-E3/54 provide for surge protection?
The 1N6385-E3/54 is rated for 1500W peak pulse power dissipation with bi-directional clamping, making it effective for protecting circuits against both positive and negative voltage transients. It belongs to the 1.5KE series and clamps surge energy on AC lines and bidirectional signal buses.
Which interface or power line protection designs benefit most from using 1N6385-E3/54?
The device suits RS-485, RS-422, and industrial I/O bus protection where bidirectional transient clamping up to 1500W is needed. Its axial 2-pin through-hole package fits directly on PCBs at signal entry points in motor drives, building automation controllers, and communication interface cards.
How does the axial 1.5KE package of 1N6385-E3/54 compare physically to surface-mount TVS alternatives?
The 1N6385-E3/54 uses a 2-pin axial through-hole 1.5KE package measuring approximately 7.5 mm in body length, which allows higher power dissipation through board and lead thermal paths compared to smaller SMD TVS packages rated for lower surge currents.
When is 1N6385-E3/54 preferred over a unidirectional TVS diode for line protection?
1N6385-E3/54 is preferred when protecting AC voltage lines or differential signal pairs where transients can arrive with either polarity. Its bi-directional 1500W peak clamping handles both positive and negative surges in a single component, eliminating the need for two back-to-back unidirectional TVS diodes.
