This document provides an overview, features, and applications of a series of general-purpose surface-mounted diodes.
The BAS70 and 1PS7xSB70 series are general‑purpose Schottky diodes offered in a variety of small surface‑mount packages such as SOT23, SOT323, SOT363 and SOT666. They are intended for ultra‑high‑speed switching, voltage clamping and low‑leakage applications.
Key electrical parameters include a typical forward voltage of 410 mV at 1 mA, a reverse voltage rating of 70 V, and a maximum forward current of 70 mA. Thermal resistance values range from 416 K/W to 700 K/W depending on the package, and the devices are rated for junction temperatures up to 150 °C. Marking codes such as “73*” identify the BAS70 part.
| Forward voltage (typical, 1 mA) | 410 mV |
|---|---|
| Reverse voltage (maximum) | 70 V |
| Forward current (maximum) | 70 mA |
| Junction temperature (maximum) | 150 °C |
| Ambient temperature range | -65 °C to +150 °C |
| Marking code (BAS70) | 73* |
The BAS70 series is rated for a reverse voltage of up to 70 V.
Typical forward voltage is 410 mV when measured at 1 mA.
The BAS70 part is marked with the code “73*”.
