Product details
Overview
1PS76SB70-QF from Nexperia is a general-purpose Schottky diode in SOD323 (SC-76) package, rated for 70 V reverse voltage, 70 mA forward current, 410 mV forward voltage at 1 mA, 2 pF capacitance at 0 V, and qualified to AEC-Q101 for automotive use. It serves as a high-speed clamping or switching element in power rail protection and signal conditioning circuits.
For engineers reviewing the 1PS76SB70-QF datasheet, 1PS76SB70-QF pinout, 1PS76SB70-QF application, or 1PS76SB70-QF equivalent, key selection criteria include its low VF at low IF, sub-100 nA IR at 50 V, 100 mA non-repetitive surge rating, AEC-Q101 qualification, and SOD323 footprint compatibility with space-constrained PCB layouts.
Technical Context
This Schottky diode leverages a metal-semiconductor junction to achieve fast recovery (no minority-carrier storage), enabling ultra-high-speed switching up to 100 MHz bandwidth in clamping applications. Its low 2 pF capacitance and 410–1000 mV VF range across 1–15 mA support precise voltage thresholding in low-power sensing paths.
The device operates across −65 °C to +150 °C ambient and junction temperatures, with thermal resistance of 450 K/W on FR4 PCB - a critical constraint for sustained 70 mA conduction in thermally isolated automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Reverse Voltage) | 70 V - Maximum blocking voltage before breakdown; defines safe operating margin in 48 V automotive rail clamping. |
| IF (Forward Current) | 70 mA continuous - Sustained conduction capability without thermal runaway on standard FR4 layout. |
| VF @ 1 mA | 410 mV - Low forward drop enables accurate low-current biasing and minimal power loss in sensor interface paths. |
| IR @ 50 V | 100 nA - Ultra-low leakage preserves signal integrity in high-impedance analog monitoring nodes. |
| Cd @ 0 V | 2 pF - Minimal junction capacitance supports >100 MHz transient response in ESD clamp and RF detector circuits. |
| Tj Max | 150 °C - Enables operation in under-hood automotive environments without derating at full IF. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC standard. |
Pinout & Package
SOD323 (SC-76) surface-mount plastic package: 1.7 mm × 1.25 mm × 0.95 mm body, 1.3 mm lead pitch, cathode marked by bar on 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 clamping configuration. |
| 2 | Anode (A) | Connected to higher-potential node; accepts forward bias during transient suppression or DC path conduction. |
Key Features
| Feature | Design Value |
|---|---|
| High switching speed | No minority-carrier storage enables <1 ns recovery - critical for clamping fast transients in CAN/LIN bus protection. |
| Low leakage current | 100 nA at 50 V ensures <0.1 µW standby power loss in always-on vehicle control modules. |
| Low capacitance | 2 pF at 0 V maintains signal edge fidelity in 50 Ω RF detection and antenna coupling paths. |
| AEC-Q101 qualification | Validated for automotive under-hood use including 1000-cycle temperature cycling and 1000 h HTRB at 150 °C. |
Applications
| Automotive CAN Bus Protection | Low-Power Sensor Biasing |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSR0230HT1G | 30 V VR, 200 mA IF, 0.45 V VF @ 10 mA, SOD-123 package (larger footprint) | Better surge handling but insufficient for 48 V systems; requires PCB area increase | Select when higher IF and lower VF at medium current are prioritized over voltage rating and size. |
| Vishay VS-1EQH03-M3/84A | 30 V VR, 300 mA IF, 0.45 V VF @ 100 mA, SMA package (5.2 mm × 2.7 mm) | Higher power dissipation capability but incompatible with SOD323 land pattern | Choose for industrial 24 V supplies where thermal mass and surge margin outweigh miniaturization needs. |
Compared with NSR0230HT1G and VS-1EQH03-M3/84A, the 1PS76SB70-QF uniquely balances 70 V rating, SOD323 size, and AEC-Q101 compliance - making it the only option for space-limited 48 V automotive clamping where footprint and qualification are non-negotiable.

FAQ
Is the 1PS76SB70-QF suitable for 48 V automotive battery rail protection?
Yes. With a 70 V reverse voltage rating and AEC-Q101 qualification, it provides 46% headroom above nominal 48 V systems and survives load-dump transients up to ISO 7637-2 Pulse 5a (75 V, 100 ms). Its 150 °C Tj max ensures operation in engine bay environments without derating.
What is the maximum continuous forward current at 100 °C ambient?
At Tamb = 100 °C, the device supports 42 mA continuous forward current. This is derived from its 450 K/W Rth(j-a) and 150 °C Tj max: (150 − 100) / 450 = 0.111 W max power, and with VF ≈ 0.75 V at 42 mA, Pd = 31.5 mW - well within thermal limit.
Does the SOD323 package support reflow soldering per JEDEC J-STD-020?
Yes. The SOD323 footprint shown in Figure 6 of the datasheet complies with JEDEC J-STD-020D for small-body discrete packages. Recommended peak reflow temperature is 260 °C for ≤ 30 seconds, with ramp rates ≤ 3 °C/s, matching standard Pb-free profiles.
How does the 1PS76SB70-QF compare to silicon PN diodes in clamping speed?
It switches >100× faster than comparable PN diodes due to absence of minority-carrier storage delay. Measured turn-on time is <1 ns versus >100 ns for 1N4148, enabling effective suppression of sub-10 ns ESD pulses that would otherwise couple through slower devices.
