Nexperia USA Inc. 1PS76SB10,135

Overview

1PS76SB10 from Nexperia is a planar Schottky barrier diode with integrated guard ring for stress protection, housed in an SOD323 surface-mount package. It delivers 400 mV forward voltage at 10 mA, 30 V reverse voltage rating, and 10 pF capacitance at 1 V - optimized for ultra-high-speed switching and reverse polarity protection in space-constrained portable electronics.

For engineers reviewing the 1PS76SB10 datasheet, 1PS76SB10 pinout, 1PS76SB10 application, or 1PS76SB10 equivalent, key selection criteria include low VF consistency across temperature, sub-10 pF junction capacitance, SOD323 footprint compatibility, and non-automotive qualification status per revision v.6 (July 2022).

Technical Context

This Schottky diode uses a planar silicon structure with an integrated guard ring to enhance ESD and transient robustness without compromising switching speed. Its low forward voltage drop and minimal junction capacitance stem from optimized metal-semiconductor interface design and shallow junction geometry.

The device operates within −55 °C to 125 °C ambient range, with thermal resistance of 450 K/W (junction-to-ambient, FR4 PCB, single-sided copper), and supports pulsed forward currents up to 600 mA (non-repetitive, 10 ms) while maintaining stable clamping behavior under line termination loads.

Key Specifications

Pinout & Package

Encapsulated in the SOD323 plastic surface-mount package (1.7 mm × 1.25 mm × 0.95 mm, 1.3 mm lead pitch), the device features a two-terminal configuration with cathode marked by a bar on the top surface.

FAQ

Is the 1PS76SB10 qualified for automotive applications?

No. Per revision v.6 (July 2022) of the datasheet, the 1PS76SB10 is explicitly designated as non-automotive qualified. Nexperia states that automotive alternatives (with -Q suffix) must be selected separately and verified against AEC-Q101 requirements. This part lacks automotive-grade process controls, testing, and documentation.

What does the 'S0' marking on the device indicate?

The 'S0' marking is the manufacturer's code for the 1PS76SB10 type, as confirmed in Table 4 of the datasheet. It appears adjacent to the cathode bar on the top surface of the SOD323 package and serves as the primary visual identification for assembly verification and traceability.

Can the 1PS76SB10 replace a standard silicon diode in reverse polarity protection?

Yes - with design validation. Its 400 mV VF at 10 mA is significantly lower than typical silicon diodes (~700–900 mV), reducing power loss and heat generation. However, its 30 V VR rating and 2 µA IR at 25 V require verification against system-level voltage transients and leakage sensitivity.

What is the maximum continuous forward current for reliable operation?

The absolute maximum continuous forward current is 200 mA (Table 5, Limiting Values). For sustained operation, thermal derating applies: at 25 °C ambient, full rating is usable; above that, power dissipation must stay below ~110 mW (based on R_th(j-a) = 450 K/W) to avoid exceeding 125 °C junction temperature.
