Product details
Overview
1PS76SB10-QZ 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 30 V reverse voltage rating, 200 mA continuous forward current, 400 mV forward voltage at 10 mA, 10 pF capacitance at 1 V, and 2 µA reverse leakage at 25 V - enabling ultra-high-speed switching and reverse polarity protection in automotive power rails.
For engineers reviewing the 1PS76SB10-QZ datasheet, 1PS76SB10-QZ pinout, 1PS76SB10-QZ application, or 1PS76SB10-QZ equivalent, key selection criteria include AEC-Q101 qualification, low VF/low Cd trade-off, thermal resistance (450 K/W), junction temperature limit (125 °C), and SOD323 footprint compatibility with high-density PCB layouts.
Technical Context
This Schottky diode uses a planar silicon structure with an integrated guard ring to suppress edge breakdown under transient stress, improving reliability in automotive environments. Its low 400 mV VF at 10 mA and 10 pF Cd at 1 V support fast switching in line termination and clamping circuits where minimal forward loss and capacitive loading are critical.
The device operates across –55 °C to +125 °C ambient and up to +125 °C junction temperature, with pulsed forward current capability up to 600 mA (10 ms). Thermal resistance of 450 K/W (junction-to-ambient, FR4, single-sided copper) defines its power dissipation limits in compact layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - maximum DC or repetitive peak reverse bias before breakdown; sets clamping threshold in protection circuits. |
| Forward Current (IF) | 200 mA continuous - defines steady-state conduction capacity without thermal runaway under rated ambient conditions. |
| Forward Voltage (VF) | 400 mV at IF = 10 mA - enables low-loss rectification and voltage clamping with minimal power dissipation. |
| Diode Capacitance (Cd) | 10 pF at VR = 1 V, f = 1 MHz - ensures minimal signal distortion and fast edge response in RF and high-speed digital interfaces. |
| Reverse Leakage (IR) | 2 µA at VR = 25 V - supports stable DC blocking and low quiescent current in always-on automotive modules. |
| Junction Temperature (Tj) | 125 °C max - constrains thermal design margin when operating near ambient limits in engine bay or infotainment enclosures. |
Pinout & Package
Encapsulated in a miniature SOD323 plastic surface-mount package (1.7 mm × 1.25 mm × 0.95 mm, 1.3 mm lead pitch), the device features a standard two-terminal configuration with cathode marked by a bar on the body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Negative terminal; marking bar on package identifies this pin - essential for correct orientation in reverse polarity protection paths. |
| 2 | Anode (A) | Positive terminal; connects to input rail or signal source - determines forward conduction direction in clamping and switching applications. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Stress-tested per automotive discrete semiconductor standard - enables use in engine control units, ADAS sensors, and body electronics without additional qualification. |
| Integrated guard ring | Suppresses edge-related avalanche breakdown - improves robustness against ESD and load dump transients in 12 V vehicle systems. |
| Low forward voltage | 400 mV at 10 mA - reduces conduction loss and self-heating in space-constrained power domains like USB-C PD and CAN bus protection. |
| Low capacitance | 10 pF at 1 V - preserves signal integrity in high-frequency data lines (e.g., LIN, SENT, or sensor analog outputs) without added filtering. |
Applications
| Ultra-High-Speed Switching | Line Termination |
|---|---|
Use Scenario: Fast-switching DC-DC converter synchronous rectification and flyback snubber networks. IC Role / Device Role / Timing Role: Low-loss freewheeling path during MOSFET off-time; replaces slower PN diodes to improve efficiency above 500 kHz. Use Value: 400 mV VF minimizes conduction loss; 10 pF Cd avoids resonance with trace inductance in <10 ns edge-rate circuits. |
Use Scenario: RS-485, CAN FD, and LVDS bus termination in automotive communication modules. IC Role / Device Role / Timing Role: AC-coupled termination clamp that absorbs overshoot while maintaining DC bias stability. Use Value: Low IR (2 µA) prevents DC offset drift; 30 V VR accommodates ±15 V common-mode swings in industrial-grade buses. |
| Voltage Clamping | Reverse Polarity Protection |
Use Scenario: Transient voltage suppression on 12 V supply inputs of telematics control units (TCUs) and head units. IC Role / Device Role / Timing Role: Fast-acting shunt clamp activated during load-dump events (>35 V spikes). Use Value: Guard ring enables reliable clamping at 30 V without premature edge breakdown; 600 mA IFSM handles 10 ms surge peaks. |
Use Scenario: Input protection for battery-powered infotainment modules connected to vehicle harnesses. IC Role / Device Role / Timing Role: Series-connected anode-to-rail diode blocking reverse connection during service or assembly. Use Value: 200 mA IF rating supports typical module loads (e.g., display backlight, MCU, audio amp); SOD323 footprint saves board area vs. larger packages. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB521S-30T2R | Higher VF (450 mV @ 10 mA), same VR (30 V), slightly higher Cd (12 pF) | Less optimal for ultra-low-loss clamping but acceptable for general-purpose reverse protection | Preferred where cost sensitivity outweighs 50 mV VF penalty and board layout allows minor Cd increase |
| NSR0230P2T5G | Lower IF rating (200 mA same, but lower IFRM = 250 mA), identical VF/Cd, no AEC-Q101 qualification | Not approved for automotive production; limited to consumer or industrial non-safety-critical use | Select only for non-automotive designs where AEC-Q101 compliance is not required and pulse current demands are modest |
Compared with RB521S-30T2R and NSR0230P2T5G, the 1PS76SB10-QZ provides the lowest VF among AEC-Q101-qualified SOD323 Schottkys and uniquely combines guard ring robustness with 600 mA surge capability - making it the preferred choice for automotive power rail protection where both efficiency and transient resilience are mandatory.

FAQ
Is the 1PS76SB10-QZ suitable for 24 V commercial vehicle applications?
No - its 30 V reverse voltage rating provides only 2 V margin above nominal 24 V systems, which is insufficient for load dump transients (up to 35–40 V). It is validated for 12 V automotive use only, where 30 V VR meets ISO 7637-2 Pulse 5a requirements with adequate safety margin.
What is the significance of the guard ring in the 1PS76SB10-QZ?
The integrated guard ring redistributes electric field concentration at the silicon periphery, preventing premature edge breakdown during voltage transients. This enhances ruggedness against ESD (IEC 61000-4-2 Level 4) and load dump surges, extending operational life in automotive power domains.
Can the 1PS76SB10-QZ be used in place of a standard 1N5817 in a PCB redesign?
Yes, but only if the SOD323 footprint and 200 mA IF rating meet the circuit's thermal and current demands. The 1PS76SB10-QZ offers lower VF (400 mV vs. ~450–600 mV) and smaller size, but lacks the 1N5817's DO-41 through-hole mounting and higher surge ratings - verify thermal performance on FR4 with 450 K/W Rth(j-a).
Does the 1PS76SB10-QZ have a specified junction-to-case thermal resistance?
No - the datasheet specifies only junction-to-ambient thermal resistance (450 K/W, FR4, single-sided copper). Junction-to-case (Rth(j-c)) is not published, as the SOD323 package lacks a defined thermal pad or metal slug; thermal design must rely on PCB copper area and airflow modeling.
