Product details
Overview
1PS76SB40,115 from Nexperia is a general-purpose Schottky diode in SOD323 (SC-76) package, designed for ultra-high-speed switching and voltage clamping. It delivers 40 V reverse voltage rating, 120 mA forward current capability, 380 mV forward voltage at 1 mA, 5 pF capacitance at 0 V, and 1 µA reverse leakage at 30 V - enabling compact, low-loss signal path protection in space-constrained DC-DC converters and interface circuits.
For engineers reviewing the 1PS76SB40,115 datasheet, 1PS76SB40,115 pinout, 1PS76SB40,115 application, or 1PS76SB40,115 equivalent, key selection criteria include its low VF/low-Cd trade-off, SOD323 footprint compatibility, pulsed-current robustness (200 mA IFSM), thermal resistance (450 K/W), and non-automotive qualification status per revision v.12.
Technical Context
This Schottky diode uses a planar epitaxial construction to achieve fast recovery (no minority-carrier storage) and low forward conduction loss. Its junction temperature limit of 150 °C and ambient operating range of −65 °C to +150 °C support use in industrial power rails and portable electronics with intermittent high-current transients.
The device exhibits typical reverse current of 1 µA at VR = 30 V and 10 µA at VR = 40 V, confirming stable blocking behavior under bias. Capacitance drops from 5 pF at 0 V to ~1 pF at 30 V reverse bias (Fig. 4), supporting RF-coupling and ESD clamp applications where dynamic impedance matters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - maximum continuous blocking voltage before breakdown; defines safe operating margin in 24 V or 36 V rail clamping. |
| Forward Voltage (VF) | 380 mV @ 1 mA - enables low-loss biasing in precision reference paths and low-current signal steering. |
| Forward Current (IF) | 120 mA continuous - supports moderate-power logic-level clamping and flyback snubbing without derating. |
| Diode Capacitance (Cd) | 5 pF @ 0 V, 1 MHz - minimizes signal distortion in <100 MHz digital lines and high-frequency detector circuits. |
| Reverse Leakage (IR) | 1 µA @ 30 V - ensures minimal standby power loss in battery-backed hold-up and sensing nodes. |
| Thermal Resistance (Rth(j-a)) | 450 K/W - requires PCB copper area management for sustained 120 mA operation above 70 °C ambient. |
| Peak Surge Current (IFSM) | 200 mA @ 10 ms - withstands transient overloads such as hot-swap inrush or ESD-induced current spikes. |
Pinout & Package
Package: SOD323 (SC-76), plastic surface-mounted, 1.7 mm × 1.25 mm × 0.95 mm body, 1.3 mm lead pitch, marking bar indicates cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Negative terminal; connects to lower-potential node in clamping or rectification; marked by bar on top surface. |
| 2 | Anode (A) | Positive terminal; ties to higher-potential source; polarity must be observed to avoid reverse conduction failure. |
Key Features
| Feature | Design Value |
|---|---|
| High switching speed | No minority-carrier storage → sub-nanosecond recovery; eliminates turn-off delay in PWM feedback paths. |
| Low leakage current | 1 µA @ 30 V enables microamp-level sleep-mode integrity in always-on sensor interfaces. |
| High breakdown voltage | 40 V VR rating provides 2× margin over common 24 V industrial bus systems. |
| Low capacitance | 5 pF Cd preserves signal edge rate in USB 2.0 data lines and GPIO protection networks. |
Applications
| DC-DC Converter Output Clamp | USB Data Line ESD Protection |
|---|---|
Use Scenario: Clamps inductive kickback from synchronous buck converter high-side FET during dead-time transitions. IC Role / Device Role / Timing Role: Fast-recovery Schottky clamp placed between output rail and ground to absorb energy and suppress overshoot. Use Value: 380 mV VF minimizes conduction loss during clamping; 200 mA IFSM handles repetitive 100 ns spikes without degradation. |
Use Scenario: Protects USB 2.0 D+ and D− lines from ±8 kV contact ESD per IEC 61000-4-2. IC Role / Device Role / Timing Role: Low-capacitance bidirectional clamp (anode-to-rail, cathode-to-ground) shunts transient current away from PHY. Use Value: 5 pF Cd avoids signal integrity degradation at 480 Mbps; 40 V VR exceeds USB VBUS tolerance. |
| Low-Power Logic-Level Shifter | RF Detector Bias Network |
Use Scenario: Level-shifts 1.8 V I²C signals to 3.3 V domain using passive diode-resistor topology. IC Role / Device Role / Timing Role: Forward-biased Schottky isolates pull-up domains while passing SDA/SCL edges with minimal delay. Use Value: 380 mV VF ensures reliable turn-on at 1.8 V logic; SOD323 size fits dense routing near SoC BGA pads. |
Use Scenario: Provides temperature-stable DC bias to GaAs FET-based RF envelope detector in 2.4 GHz ISM band receivers. IC Role / Device Role / Timing Role: Low-leakage anode-to-VDD path establishes stable gate bias point independent of RF amplitude. Use Value: 1 µA IR at 30 V prevents drift in detector offset; 150 °C Tj rating supports operation near PA stages. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAS40-04,115 | Same SOD323 package; 40 V VR, but VF = 440 mV @ 1 mA (60 mV higher); IR = 0.5 µA @ 30 V (lower leakage). | Better leakage performance suits ultra-low-power RTC backup; higher VF reduces efficiency in high-duty-cycle clamping. | Select when leakage dominates design concern and VF margin >60 mV is acceptable. |
| 1PS79SB40,115 | Same family; identical VF/Cd/VR specs, but rated for automotive (-Q) qualification per AEC-Q101. | Qualified for under-hood automotive modules; same electrical behavior but higher test rigor and traceability. | Choose only if automotive qualification is contractually required; otherwise, 1PS76SB40,115 offers cost and lead-time advantage. |
Compared with BAS40-04,115, 1PS76SB40,115 trades 60 mV lower VF for slightly higher leakage - favoring efficiency-critical clamping. Versus 1PS79SB40,115, it omits automotive qualification, reducing cost and simplifying supply chain for industrial designs.

FAQ
Is the 1PS76SB40,115 qualified for automotive applications?
No. Per revision v.12 (January 2023), this part is explicitly designated non-automotive qualified. Nexperia offers the 1PS79SB40,115 as the automotive-qualified (-Q) alternative meeting AEC-Q101 requirements. Use of 1PS76SB40,115 in automotive systems voids warranty and violates safety compliance protocols.
What is the meaning of the 'S4' marking on the device?
The 'S4' laser marking on the top surface identifies the 1PS76SB40,115 per Table 4 of the datasheet. The bar adjacent to pin 1 denotes the cathode terminal. This marking is consistent across all SOD323-packaged units and enables visual polarity verification during manual assembly or optical inspection.
Can the 1PS76SB40,115 replace BAS40 in existing designs?
Yes, with validation. Both share SOD323 package, 40 V VR, and Schottky architecture, but 1PS76SB40,115 has 380 mV VF vs. BAS40's 440–500 mV, and 5 pF Cd vs. BAS40's 5–10 pF. Lower VF improves efficiency; tighter Cd tolerance aids high-frequency stability. Thermal resistance differs (450 K/W vs. ~400 K/W), so board layout review is recommended.
What is the maximum allowable soldering temperature profile for SOD323 reflow?
Per Figure 6, the recommended reflow profile uses standard SnPb or lead-free paste with peak temperature ≤260 °C for ≤10 seconds. The SOD323 package withstands JEDEC J-STD-020 moisture sensitivity level 1 (unlimited floor life), and the 0.95 mm max height allows compatibility with automated pick-and-place and 0201-class placement accuracy.
