Product details
Overview
1PS70SB14F from Nexperia is a dual Schottky barrier diode in series configuration with integrated guard ring for stress protection, housed in an SOT323 (SC-70) package. It delivers 30 V reverse voltage rating, 200 mA forward current per diode, and 400 mV typical forward voltage at 10 mA, enabling ultra-high-speed switching and reverse polarity protection in space-constrained automotive and industrial circuits.
For engineers reviewing the 1PS70SB14F datasheet, 1PS70SB14F pinout, 1PS70SB14F application, or 1PS70SB14F equivalent, key selection criteria include its AEC-Q101 qualification, low 10 pF capacitance at 1 V, 2 µA max reverse leakage at 25 V, and series-connected dual-diode topology for compact clamping and termination designs.
Technical Context
The 1PS70SB14F integrates two Schottky diodes in series-Anode1–Cathode1–Anode2–Cathode2-with shared terminal 3 serving as both K1 and A2. This configuration enables bidirectional clamping or unidirectional current steering without external interconnection.
Its planar Schottky construction ensures low forward voltage and fast recovery, while the integrated guard ring enhances ESD and transient robustness. Thermal resistance is 625 K/W (junction-to-ambient, FR4 PCB), and operation is specified from −55 °C to +150 °C ambient.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSR20F30HT1G | Single dual-Schottky in SOD-323; 30 V VR, 200 mA IF, VF = 450 mV @ 10 mA; no AEC-Q101 rating. | Not qualified for automotive use; suitable for commercial-grade USB/LVDS protection only. | Select when AEC-Q101 is not required and board space allows SOD-323 footprint. |
| Vishay VS-2EDH03-M3/84A | Series dual Schottky in SOT-23; 30 V VR, 200 mA IF, VF = 420 mV @ 10 mA; AEC-Q101 qualified. | SOT-23 package (larger than SOT323); higher thermal resistance (500 K/W vs. 625 K/W). | Choose when existing SOT-23 layout exists and tighter thermal margin is acceptable. |
Compared with NSR20F30HT1G and VS-2EDH03-M3/84A, the 1PS70SB14F uniquely combines AEC-Q101 qualification, SC-70 footprint, and 10 pF capacitance-making it optimal for space-limited automotive signal protection where low parasitic loading is critical.

FAQ
What is the maximum peak forward current the 1PS70SB14F can handle?
The 1PS70SB14F supports a non-repetitive peak forward current (IFSM) of 600 mA for pulses less than 10 ms at 25 °C initial junction temperature. Its repetitive peak forward current (IFRM) is rated at 300 mA for duty cycles ≤ 0.5 and pulse widths ≤ 1 s. These values define safe surge-handling limits during ESD or load-dump events.
Can the 1PS70SB14F be used for bidirectional ESD protection?
No-the 1PS70SB14F has a fixed series configuration (A1–K1/A2–K2) and is unidirectional. It provides clamping from signal to VCC or GND depending on biasing, but lacks symmetrical anode-cathode symmetry required for true bidirectional TVS action. For bidirectional protection, discrete back-to-back Schottky pairs or dedicated TVS arrays are required.
Is thermal derating required for operation above 25 °C ambient?
Yes-total power dissipation is limited to 200 mW at Tamb < 25 °C. With a thermal resistance of 625 K/W, each 1 °C rise above 25 °C reduces allowable power by ~0.32 mW. At 85 °C ambient, maximum continuous power drops to ~10 mW per diode, requiring current reduction to ~25 mA to maintain safe junction temperature.
Does the 1PS70SB14F require external biasing for clamping operation?
No-clamping occurs passively when the applied voltage exceeds the forward voltage of either diode branch. When used for supply rail clamping, connect Pin 1 to the protected line, Pin 2 to GND (for positive clamping) or VCC (for negative clamping), and leave Pin 3 floating or tie to reference as needed. No external bias circuitry is required.
