Product details
Overview
1PS76SB70 from Nexperia is a general-purpose Schottky diode in SOD323 (SC-76) package, designed for ultra-high-speed switching and voltage clamping. It delivers 70 V reverse voltage rating, 70 mA forward current capability, 410 mV forward voltage at 1 mA, 2 pF capacitance at 0 V, and 100 nA reverse leakage at 50 V - enabling compact, low-loss signal path protection in space-constrained consumer and industrial power rails.
For engineers reviewing the 1PS76SB70 datasheet, 1PS76SB70 pinout, 1PS76SB70 application, or 1PS76SB70 equivalent, key selection criteria include its low VF/low-Cd trade-off, cathode-marked SOD323 footprint compatibility, pulsed forward voltage behavior, and thermal resistance of 450 K/W on FR4 - critical for high-frequency clamp and flyback snubber designs.
Technical Context
This Schottky diode leverages a planar epitaxial construction to achieve fast recovery with negligible minority-carrier storage, supporting operation up to several hundred MHz in clamping and RF detector roles. Its junction temperature limit of 150 °C and ambient range of −65 °C to +150 °C support deployment in extended-temperature industrial modules.
The device exhibits strong temperature dependence in forward voltage (VF drops ~1.2 mV/°C) and reverse leakage (IR increases >10× from 25 °C to 125 °C), requiring thermal-aware layout in high-reliability DC-DC feedback paths and ESD-coupled I/O protection circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 70 V - supports clamp operation across 48 V industrial bus transients without breakdown. |
| Forward Voltage (VF) | 410 mV @ 1 mA - minimizes conduction loss in low-current bias and sensing paths. |
| Reverse Leakage (IR) | 100 nA @ 50 V - ensures minimal standby current drain in battery-backed circuits. |
| Capacitance (Cd) | 2 pF @ 0 V, 1 MHz - enables clean high-frequency signal routing without parasitic loading. |
| Thermal Resistance (Rth(j-a)) | 450 K/W - defines derating curve on standard FR4; limits continuous IF to ~35 mA at Tamb = 85 °C. |
| Peak Forward Current (IFSM) | 100 mA @ 10 ms - withstands short-duration surge events like ESD-induced current spikes. |
Pinout & Package
Package: SOD323 (SC-76), surface-mount plastic package, 1.7 mm × 1.25 mm × 0.95 mm body, 1.3 mm lead pitch, cathode indicated by marking bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to lower-potential node; marking bar aligns with this pin for visual polarity verification during placement. |
| 2 | Anode (A) | Connected to higher-potential node; forms forward-biased path when A > K by ≥410 mV. |
Key Features
| Feature | Design Value |
|---|---|
| High switching speed | Sub-nanosecond recovery enabled by Schottky barrier - avoids minority-carrier delay in pulse shaping. |
| Low leakage current | 100 nA at 50 V allows use in microamp-level sensor bias networks without offset drift. |
| Low capacitance | 2 pF enables integration into 500 MHz+ RF detector front-ends without signal attenuation. |
| High breakdown voltage | 70 V VR rating permits direct use in 24–48 V system clamping without series stacking. |
Applications
| USB Data Line Protection | DC-DC Converter Feedback Clamp |
|---|---|
Use Scenario: Protecting USB 2.0 D+/D− lines from ESD and overvoltage transients while preserving signal integrity. IC Role / Device Role / Timing Role: Low-capacitance shunt clamp that conducts only above 70 V, remaining transparent below. Use Value: 2 pF capacitance avoids signal rise-time degradation; 410 mV VF ensures no forward conduction during normal 3.3 V signaling. |
Use Scenario: Clamping error amplifier output in isolated flyback converters to prevent saturation during load dump. IC Role / Device Role / Timing Role: Fast-reacting voltage limiter placed between optocoupler input and reference node. Use Value: 100 mA non-repetitive peak rating absorbs transient energy; 450 K/W Rth(j-a) allows safe dissipation on small PCB copper areas. |
| Low-Power Sensor Bias Network | RF Detector Diode |
Use Scenario: Providing stable reverse-biased bias to photodiode or MEMS sensor elements in battery-powered IoT nodes. IC Role / Device Role / Timing Role: Reverse-blocking element maintaining high impedance above 50 V while leaking <100 nA at operating voltage. Use Value: Ultra-low IR prevents battery drain over years; 150 °C Tj rating supports sealed enclosure thermal profiles. |
Use Scenario: Demodulating 433 MHz ISM band RF signals in wireless sensor receivers. IC Role / Device Role / Timing Role: Zero-bias envelope detector leveraging Schottky's low turn-on voltage and minimal junction capacitance. Use Value: 2 pF Cd and sub-500 mV VF enable efficient rectification at −20 dBm input levels without external bias. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAS70-04,115 | Same SOD323 package; 70 V VR, but VF = 800 mV @ 10 mA - higher conduction loss at moderate currents. | Less suitable for low-current bias networks where <500 mV VF is required. | Prefer when higher surge robustness (IFSM = 200 mA) outweighs VF penalty. |
| 1PS79SB70,115 | Identical electrical specs and pinout; differs only in marking code (S3 vs S2) and minor process revision. | No functional difference; fully interchangeable in all designs. | Select for dual-sourcing continuity if 1PS76SB70 supply is constrained. |
Compared with BAS70-04,115, 1PS76SB70 offers lower VF for precision low-current clamping; compared with 1PS79SB70,115, it shares identical performance but reflects an earlier production revision - both support drop-in replacement in legacy and new designs.

FAQ
Is the 1PS76SB70 suitable for automotive applications?
No. The 1PS76SB70 is not AEC-Q200 qualified and lacks automotive-grade screening, temperature cycling validation, or PPAP documentation. Nexperia explicitly states non-automotive qualification in its legal disclaimers. For automotive use, consider AEC-Q200-certified alternatives such as PMEG2010CPA or BAS70J.
What is the maximum continuous forward current at 85 °C ambient?
Based on Rth(j-a) = 450 K/W and Tj(max) = 150 °C, the allowable temperature rise is 65 K. With θja = 450 K/W, maximum steady-state power dissipation is 144 mW. Using VF ≈ 0.75 V at 15 mA (per datasheet Fig. 1), continuous IF is limited to approximately 35 mA at Tamb = 85 °C to maintain Tj ≤ 150 °C.
Does the marking 'S2' correspond to the full part number?
Yes. Per Table 4 of the datasheet, 'S2' is the official top-side marking for 1PS76SB70. This two-character code is laser-etched on the cathode end of the SOD323 body and aligns with the cathode bar - serving as the sole visual identifier for automated optical inspection and manual verification.
Can the 1PS76SB70 be used in place of a 1N5711?
No. Although both are Schottky diodes, the 1N5711 uses DO-35 glass package (5.2 mm length), has VR = 70 V but VF = 1 V @ 10 mA, and Cd = 5 pF - making it incompatible with SOD323 footprints and unsuitable for high-frequency or low-VF applications. Physical and electrical mismatches preclude substitution without board redesign.
