This document describes the features and characteristics of the dual series switching diodes, LBAV99WT1 and LBAV99RWT1, produced by LESHAN RADIO COMPANY, LTD. They have a reverse voltage of 70V and a forward current of 215mA. They are suitable for applications such as ESD protection, polarity reversal protection, data line protection, inductive load protection, and steering logic.
The LBAV99WT1 and LBAV99RWT1 are dual‑series switching diodes offered in a compact SOT‑323 (SC‑70) package. They are intended for applications such as ESD protection, polarity reversal protection, data line protection, inductive load protection, and steering logic.
The datasheet lists key electrical ratings (70 V reverse voltage, 215 mA forward current, 500 mA peak surge), thermal characteristics (200 mW dissipation, 625 °C/W thermal resistance for FR‑5 board), and ordering information (tape & reel, device marking).
| Forward Current | 215 mA |
|---|---|
| Peak Forward Surge Current | 500 mA |
| Total Device Dissipation (FR‑5 board) | 200 mW |
| Thermal Resistance (FR‑5 board) | 625 °C/W |
| Junction and Storage Temperature | -65 to +150 °C |
| Diode Capacitance | 15 pF |
| Forward Voltage (1 mA) | 0.715 V |
| Reverse Recovery Time | 6.0 ns |
They are recommended for ESD protection, polarity reversal protection, data line protection, inductive load protection, and steering logic.
Both diodes are supplied in a SOT‑323 (SC‑70) tape & reel package.
The thermal resistance from junction to ambient is 625 °C/W for the FR‑5 board.
