This data sheet provides information on the 1N6469US to 1N6476US series of voidless hermetically sealed surface mount unidirectional transient voltage suppressors (TVS) with 1500W ratings.
The Microsemi 1N6469US‑1N6476US series are voidless‑hermetically sealed surface‑mount unidirectional transient voltage suppressors (TVS) designed for high‑reliability applications where failure cannot be tolerated. They are MIL‑PRF‑19500/552 qualified and offered in both surface‑mount and axial‑lead (thru‑hole) packages.
Key features include a wide working peak standoff voltage range, high peak pulse power capability, robust glass construction with internal metallurgical bonds, and compliance with ESD, EFT, and lightning protection standards. The datasheet provides detailed electrical characteristics, mechanical dimensions, and recommended mounting guidelines.
| Working Peak Standoff Voltage (Vy) | 5.0 V – 51.6 V |
|---|---|
| Peak Pulse Power (Ppp) | 1500 W @ 10/1000 µs |
| Forward Surge Current | 130 A @ 8.33 ms one‑half sine wave |
| Operating & Storage Temperature | -55 °C to +175 °C |
| Maximum Solder Temperature | 260 °C for 10 s |
| Weight | 1100 mg |
The devices are rated for a peak pulse power of 1500 W at 25 °C (10/1000 µs pulse).
They operate from –55 °C up to +175 °C for both storage and normal operation.
The forward surge current is rated at 130 A for an 8.33 ms half‑sine waveform.
