Product details
Overview
1PS76SB10Z 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 - enabling ultra-high-speed switching and reverse polarity protection in space-constrained portable electronics.
For engineers reviewing the 1PS76SB10Z datasheet, 1PS76SB10Z pinout, 1PS76SB10Z application, or 1PS76SB10Z equivalent, key selection criteria include low VF for power efficiency, low Cd for high-frequency signal integrity, thermal resistance of 450 K/W on FR4, and SOD323 footprint compatibility with automated assembly.
Technical Context
This Schottky diode uses a planar silicon structure with an integrated guard ring to suppress edge breakdown and improve ruggedness under transient stress. Its low-barrier metal-semiconductor junction enables fast recovery (no minority-carrier storage) and minimal reverse recovery charge.
The device operates across –55 °C to +125 °C ambient, with junction temperature limited to 125 °C. Thermal resistance of 450 K/W (junction-to-ambient, FR4, single-sided copper) defines its power dissipation ceiling at ~111 mW under natural convection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VF @ 10 mA | 400 mV - Enables <110 mW conduction loss in 3.3 V rail clamping paths |
| VR | 30 V - Supports USB 2.0/3.0 and 24 V industrial I/O line termination |
| Cd @ 1 V | 10 pF - Maintains signal integrity up to ~1.6 GHz in RF front-end bias networks |
| IF(max) | 200 mA continuous - Suitable for low-power load-switching and ESD clamp hold-off |
| Rth(j-a) | 450 K/W - Limits thermal rise to ~50 K at 111 mW on standard FR4 PCB |
| IR @ 25 V | 2 µA - Ensures <50 nW leakage in battery-backed backup circuits |
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 package top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to circuit ground or lower-potential node; marking bar aligns with this pin |
| 2 | Anode (A) | Connected to input voltage or signal source; current flows from A to K during forward bias |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Suppresses edge leakage and improves voltage standoff reliability under ESD or surge stress |
| Low forward voltage | 400 mV @ 10 mA reduces conduction loss in battery-powered load switches |
| Low capacitance | 10 pF @ 1 V minimizes signal distortion in high-speed data line termination (e.g., USB D+/D–) |
| SOD323 footprint | Enables high-density placement in wearables and IoT sensor nodes with <2.2 mm² board area |
Applications
| USB Data Line Protection | Portable Device Reverse Polarity Protection |
|---|---|
Use Scenario: Clamping D+ and D− lines against ESD transients in smartphone accessory ports. IC Role / Device Role / Timing Role: Passive voltage clamp placed directly at connector interface, operating in reverse-biased standby and forward-conducting during overvoltage events. Use Value: 10 pF capacitance preserves USB 2.0 signal rise/fall times; 400 mV VF ensures minimal insertion loss during normal operation. | Use Scenario: Preventing damage when users incorrectly insert barrel-jack power adapters into handheld medical monitors. IC Role / Device Role / Timing Role: Series anode-cathode path in main power input, conducting only when polarity is correct. Use Value: 400 mV VF limits voltage drop to <0.5% on a 12 V supply, preserving regulation margin for downstream LDOs. |
| High-Speed Logic Interface Termination | Low-Power Signal-Level Shifting |
Use Scenario: Terminating LVDS or CMOS clock outputs in FPGA-to-ADC interconnects on compact PCBs. IC Role / Device Role / Timing Role: DC-coupled termination to VCC or ground, absorbing reflections without adding RC delay. Use Value: 10 pF capacitance avoids degrading edge rates beyond 1 ns; 30 V VR accommodates 3.3 V/5 V logic swing margins. | Use Scenario: Level-shifting I²C signals between 1.8 V microcontroller GPIOs and 3.3 V sensor modules. IC Role / Device Role / Timing Role: Cathode-connected to higher-voltage rail, anode to lower-rail signal line - enabling passive bidirectional translation. Use Value: 2 µA IR at 25 V ensures <100 nA leakage per bus line, preventing false ACK/NACK in multi-drop configurations. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB520S-30T1G | VF = 370 mV @ 10 mA; Cd = 15 pF @ 1 V; same SOD-323 package | Higher capacitance limits use above 1 GHz; better VF suits ultra-low-power bias networks | Prefer for lowest conduction loss where RF bandwidth <1 GHz is acceptable |
| BAT54C,215 | VF = 420 mV @ 10 mA; Cd = 12 pF @ 1 V; dual-diode SOT-323 package | Dual configuration supports complementary signal paths; larger footprint increases board area by 2.5× | Choose when dual-channel clamping or matched pair routing is required |
Compared with RB520S-30T1G and BAT54C,215, the 1PS76SB10Z offers the best balance of low capacitance (10 pF) and compact size (SOD323), making it optimal for high-frequency, space-constrained applications where single-diode functionality suffices.

FAQ
What is the maximum continuous forward current rating for 1PS76SB10Z?
The absolute maximum continuous forward current (IF) is 200 mA at Tamb = 25 °C. Derating applies above 25 °C ambient: junction temperature must remain ≤125 °C, and thermal resistance is 450 K/W on standard FR4 PCB. At 85 °C ambient, max IF drops to approximately 133 mA to maintain Tj ≤125 °C.
Does 1PS76SB10Z have automotive qualification?
No. The 1PS76SB10Z is explicitly designated as non-automotive qualified per Nexperia's revision history (v.6, July 2022). It lacks AEC-Q101 qualification and is not tested to automotive reliability standards. For automotive applications, Nexperia recommends its -Q qualified equivalents such as 1PS76SB10Q.
How is the cathode identified on the 1PS76SB10Z package?
The cathode is marked by a visible bar on the top surface of the SOD323 package and corresponds to Pin 1 per the official pinning diagram. This marking aligns with the cathode symbol (K) in the simplified outline and matches industry-standard SOD323 orientation conventions used in pick-and-place and solder paste stencil design.
Can 1PS76SB10Z be used in RF matching networks?
Yes - its 10 pF capacitance at 1 V reverse bias and low series resistance support use in UHF matching (up to ~1.6 GHz) for antenna tuning or PA bias networks. However, it is not characterized for RF-specific parameters like Q-factor or S-parameters; designers should validate impedance behavior empirically at target frequencies and bias points.
