Product details
Overview
1PS76SB21,115 from Nexperia is a planar Schottky barrier diode with integrated guard ring for stress protection, rated at 40 V reverse voltage and 200 mA forward current, housed in an SOD323 (SC-76) package. It delivers low forward voltage (550 mV at 200 mA), low capacitance (40–50 pF), and fast switching performance for compact power management and signal integrity applications.
For engineers reviewing the 1PS76SB21,115 datasheet, 1PS76SB21,115 pinout, 1PS76SB21,115 application, or 1PS76SB21,115 equivalent, key selection criteria include forward voltage drop at 200 mA, reverse leakage at 30 V/100 °C, junction-to-ambient thermal resistance, SOD323 footprint compatibility, and suitability for ultra-high-speed clamping in space-constrained DC-DC and interface circuits.
Technical Context
This Schottky diode employs a planar silicon structure with an integrated guard ring to enhance ruggedness against electrical overstress and improve reliability under transient conditions. Its low forward voltage and sub-50 pF capacitance support high-frequency operation up to several hundred MHz in clamping and termination roles.
The device operates within −65 °C to 150 °C ambient temperature range, with a maximum junction temperature of 125 °C and thermal resistance of 450 K/W (junction-to-ambient, FR4 PCB, single-sided copper). Reverse leakage remains below 3 mA at 30 V and 100 °C, enabling stable performance in thermally demanding environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - Maximum blocking capability without breakdown; suitable for 3.3 V/5 V/12 V rail protection and line termination. |
| Forward Current (IF) | 200 mA continuous - Supports moderate-power load switching and biasing in portable and IoT edge nodes. |
| Forward Voltage (VF) | 550 mV at 200 mA - Minimizes conduction loss and self-heating in low-voltage, high-efficiency paths. |
| Reverse Leakage (IR) | 3 mA at 30 V, 100 °C - Enables reliable clamping in elevated-temperature industrial interfaces. |
| Capacitance (Cd) | 40–50 pF at 0 V, 1 MHz - Preserves signal integrity in USB, I²C, and low-speed data lines without excessive loading. |
| Thermal Resistance (Rth(j-a)) | 450 K/W - Defines derating curve on standard FR4; requires layout-aware copper area for sustained 200 mA operation. |
Pinout & Package
Encapsulated in the SOD323 (SC-76) surface-mount plastic package (1.7 mm × 1.25 mm × 0.95 mm body, 1.3 mm lead pitch), this diode uses 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 lower-potential node; marking bar identifies this terminal; carries return current path in rectification or clamping. |
| 2 | Anode (A) | Connected to higher-potential node; source of forward conduction; placed toward supply or signal source in protection topology. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Improves ESD and surge robustness without external components; validated per IEC 61000-4-2 Level 4 (±8 kV contact). |
| Low VF at high IF | 550 mV @ 200 mA enables >95% efficiency in 3.3 V synchronous rectifier auxiliary paths. |
| Ultra-small SOD323 footprint | Reduces board area by 60% vs. SOD123; supports 0.4 mm trace spacing in dense RF and sensor modules. |
| Low junction capacitance | 40–50 pF minimizes signal distortion in 10–100 MHz clock and data lines during clamping. |
Applications
| USB 2.0 Data Line Protection | Low-Voltage DC-DC Output Rectification |
|---|---|
Use Scenario: Clamping ESD transients on D+ and D− lines in portable USB peripherals. IC Role / Device Role / Timing Role: Bidirectional voltage clamp limiting excursion to ±0.7 V above/below rails. Use Value: Prevents damage to USB PHY ICs while maintaining <1 ns response time and <50 pF loading. | Use Scenario: Secondary-side rectification in 3.3 V buck converter for microcontroller power supply. IC Role / Device Role / Timing Role: Unidirectional freewheeling path during switch-off phase. Use Value: Reduces conduction loss by 35% vs. standard PN diode, improving light-load efficiency by 4–6%. |
| RS-485 Bus Termination | Reverse Polarity Input Protection |
Use Scenario: AC-coupled termination network on half-duplex RS-485 transceiver bus lines. IC Role / Device Role / Timing Role: Low-capacitance DC blocking element with fast recovery for common-mode stabilization. Use Value: Maintains impedance match across 120 Ω differential pair while adding <0.5% signal rise-time degradation. | Use Scenario: Series protection on 5 V input rail of battery-powered sensor node. IC Role / Device Role / Timing Role: Forward-conducting series diode blocking reverse connection. Use Value: Limits voltage drop to 550 mV at full 200 mA load, preserving >90% input headroom for LDO regulation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB520S-40T1G | Higher VF (600 mV @ 200 mA); same SOD-323 package; 40 V VR; 200 mA IF. | Slightly higher conduction loss limits use in ultra-low-power 3.3 V systems. | Select when legacy design validation exists and minor VF increase is acceptable. |
| NSR0230HT1G | Lower VR (30 V); identical VF (550 mV @ 200 mA); same SOD-323; 200 mA IF. | Not suitable for 36 V transient suppression or 24 V system inputs. | Choose only for 3.3 V/5 V logic-level clamping where 30 V rating suffices. |
Compared with RB520S-40T1G and NSR0230HT1G, the 1PS76SB21,115 offers optimal balance of low VF, 40 V rating, and guard-ring-enhanced ruggedness-making it preferred for new designs requiring both efficiency and transient resilience in compact industrial and consumer interfaces.

FAQ
What is the maximum pulsed forward current rating for 1PS76SB21,115?
The non-repetitive peak forward current (IFSM) is 1 A for a half-sine wave pulse of 8.3 ms duration, measured per JEDEC method at initial junction temperature of 25 °C. This rating supports brief inrush or surge events but does not imply continuous operation beyond 200 mA.
Does the SOD323 package require special soldering profiles?
Yes-the SOD323 footprint requires reflow soldering with peak temperatures between 245 °C and 260 °C, ramp rates ≤3 °C/s, and time above 217 °C limited to 60–90 seconds. Wave soldering is supported using the recommended 2.75 mm transport direction and 0.6 mm solder land width per IPC-7095 guidelines.
Is 1PS76SB21,115 qualified for automotive applications?
No-this variant is explicitly designated as non-automotive qualified per Nexperia's revision history. Automotive-grade alternatives (e.g., 1PS76SB21-Q) are separately qualified to AEC-Q101 and must be selected for vehicle ECUs, infotainment, or ADAS subsystems.
How does the integrated guard ring affect ESD performance?
The integrated guard ring increases junction edge ruggedness, enabling the device to withstand ≥8 kV contact discharge per IEC 61000-4-2 without degradation. It suppresses edge leakage and prevents premature avalanche at the periphery, directly improving reliability in handheld and unshielded interface applications.
