1PSxSB17 is a low capacitance Schottky diode from Philips. It is available in SOT666, SOD323 and SOD523 packages. The rated working voltage is 4V and the rated current is 30mA. The diode has low capacitance, low voltage drop and small package, which makes it suitable for digital and RF circuits.
This document is a product datasheet for the Philips 1PSxSB17 series of planar low capacitance Schottky barrier diodes. These devices are encapsulated in very small surface-mount device (SMD) plastic packages designed for digital and RF applications, including ultra high-speed switching, clamping circuits, diode ring mixers, RF detectors, and RF voltage doublers.
The datasheet provides comprehensive technical details including pinning information for three package configurations: SOT666 (triple isolated), SOD323 (SC-76 single), and SOD523 (SC-79 single). It lists quick reference data such as a maximum continuous forward current of 30 mA and a reverse voltage of 4 V, along with detailed characteristics for forward voltage, reverse current, and diode capacitance under various conditions.
| Continuous forward current (IF) | 30 mA |
|---|---|
| Continuous reverse voltage (VR) | 4 V |
| Diode capacitance (Cd) typical | 0.8 pF |
| Junction temperature (Tj) | -65 +150 °C |
| Thermal resistance (SOD323) | 450 K/W |
The device is available in three packages: SOT666 (triple isolated), SOD323 (SC-76 single), and SOD523 (SC-79 single).
It is used in digital applications like ultra high-speed switching and clamping circuits, as well as RF applications such as diode ring mixers and RF detectors.
