Product details
Overview
1PS76SB10-QX from Nexperia is a planar Schottky barrier single 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/1 MHz - optimized for ultra-high-speed switching and reverse polarity protection in automotive power rails.
For engineers reviewing the 1PS76SB10-QX datasheet, 1PS76SB10-QX pinout, 1PS76SB10-QX application, or 1PS76SB10-QX equivalent, key selection criteria include low VF consistency across temperature, AEC-Q101 qualification, SOD323 footprint compatibility, and sub-1 ns reverse recovery performance confirmed in pulsed test conditions.
Technical Context
This Schottky diode uses a planar silicon structure with guard ring to suppress edge breakdown under transient stress, enabling reliable operation up to 125 °C junction temperature. Its low 10 pF capacitance and sub-1 ns reverse recovery support high-frequency line termination and clamping in CAN FD and LIN bus interfaces.
The device operates within strict AEC-Q101 automotive stress limits: 30 V VR, 200 mA continuous IF, and 600 mA non-repetitive IFSM. Thermal resistance of 450 K/W (junction-to-ambient, FR4 PCB) defines its derating behavior in compact automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Voltage (VF) | 400 mV @ 10 mA, pulsed - enables low-loss 3.3 V/5 V rail clamping without thermal runaway |
| Reverse Voltage (VR) | 30 V - supports 24 V automotive systems with 2× safety margin against load dump transients |
| Diode Capacitance (Cd) | 10 pF @ 1 V, 1 MHz - preserves signal integrity in >100 MHz data lines and ESD-coupled paths |
| Reverse Current (IR) | 2 µA @ 25 V - ensures minimal leakage in always-on battery monitoring circuits |
| Junction Temperature (Tj) | 125 °C max - validated for under-hood ECUs and ADAS domain controllers per AEC-Q101 |
| Thermal Resistance (Rth(j-a)) | 450 K/W - defines maximum power dissipation of 111 mW on standard FR4 PCB |
Pinout & Package
Encapsulated in a 1.7 mm × 1.25 mm × 0.95 mm SOD323 plastic surface-mount package with 1.3 mm lead pitch and cathode-marked top-side bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to system ground or lower-potential node; marked by visible bar on package top |

Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Prevents premature edge breakdown under repetitive voltage transients in automotive environments |
| AEC-Q101 qualification | Validated for automotive use including temperature cycling, HTRB, and ESD testing per JESD22-A114 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSR0230HT1G | Higher VF (450 mV @ 10 mA), same SOD-323 package, no AEC-Q101 qualification | Acceptable for consumer-grade USB power paths but not qualified for automotive ECU use | Select when AEC-Q101 is not required and 50 mV higher VF is tolerable |
| Vishay VS-2EDH01-M3/84A | Higher VR (40 V), larger SOD-123 package (2.7 mm × 1.6 mm), VF = 410 mV @ 10 mA | Better surge margin for 36 V industrial systems but occupies 2.3× more PCB area | Select when 40 V VR is mandatory and board space allows SOD-123 footprint |
Compared with NSR0230HT1G and VS-2EDH01-M3/84A, the 1PS76SB10-QX uniquely balances AEC-Q101 compliance, SOD323 miniaturization, and 400 mV VF - making it optimal for space-constrained automotive modules where qualification and size are non-negotiable.

FAQ
Is the 1PS76SB10-QX suitable for continuous DC blocking in 24 V automotive systems?
Yes. With a rated 30 V reverse voltage and 200 mA continuous forward current, it supports sustained operation in 24 V nominal systems, including worst-case scenarios like 28.5 V alternator regulation and ISO 7637-2 pulse 5a (load dump). Derating per Rth(j-a) = 450 K/W is required above 85 °C ambient.
What does the "S0" marking on the device indicate?
The "S0" marking is the manufacturer-specific code for the 1PS76SB10-QX variant, as defined in Nexperia's ordering information table. It appears adjacent to the cathode bar on the top surface of the SOD323 package and serves as a visual identification aid during manual inspection and automated optical recognition.
How does the guard ring improve reliability in automotive applications?
The integrated guard ring mitigates electric field crowding at the silicon periphery, preventing premature avalanche breakdown during repetitive transients such as ISO 7637-2 pulses or ESD events. This extends operational lifetime in under-hood environments where thermal cycling and voltage stress coexist.
Can this diode be used in reflow soldering processes?
Yes. The SOD323 package is qualified for standard lead-free reflow profiles (J-STD-020), with peak temperatures up to 260 °C. Nexperia provides specific footprint dimensions in Figure 5 of the datasheet, including solder land size, solder resist openings, and paste stencil recommendations for optimal wetting and void control.
