Product details
Overview
1PS70SB14 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, 400 mV typical forward voltage at 10 mA, 10 pF capacitance at 1 V/1 MHz, and AEC-Q101 qualification - enabling use in automotive-grade line termination and reverse polarity protection circuits.
For engineers reviewing the 1PS70SB14 datasheet, 1PS70SB14 pinout, 1PS70SB14 application, or 1PS70SB14 equivalent, key selection criteria include its low VF (400 mV @ 10 mA), ultra-low Cd (10 pF), series-connected dual-diode topology, AEC-Q101 qualification, and SC-70 footprint compatibility with high-density PCB layouts.
Technical Context
The 1PS70SB14 integrates two Schottky diodes in series - anode1–cathode1–anode2–cathode2 - sharing terminal 3 as K1/A2. This configuration enables bidirectional clamping and unidirectional current blocking across compact signal paths without external series wiring.
Its planar Schottky structure ensures fast switching (no minority-carrier storage), while the integrated guard ring enhances ESD robustness and reverse-bias stability up to 30 V. Thermal resistance of 625 K/W (junction-to-ambient, FR4, single-sided copper) defines power derating limits under real-world board conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | Dual Schottky diodes in series (A1–K1/A2–K2) |
| VR (Reverse Voltage) | 30 V - sets maximum allowable DC or peak AC reverse bias before breakdown |
| VF (Forward Voltage) | 400 mV @ IF = 10 mA, 25 °C - enables low-loss signal clamping and voltage translation |
| Cd (Capacitance) | 10 pF @ VR = 1 V, f = 1 MHz - supports >100 MHz signal integrity in RF and high-speed digital lines |
| IF (Forward Current) | 200 mA continuous per diode - supports moderate-power rail protection and termination loads |
| AEC-Q101 Qualified | Validated for automotive applications including engine control, infotainment, and body electronics |
Pinout & Package

| 3 | Cathode of Diode 1 / Anode of Diode 2 (K1, A2) | Internal series junction - electrically isolated from PCB; no external connection required |
Key Features

Applications
| Automotive CAN Bus Termination | USB Port Reverse Polarity Protection |
|---|---|
Use Scenario: Termination of high-speed CAN FD differential pairs in vehicle ECUs and gateway modules.

IC Role / Device Role / Timing Role: Bidirectional clamping diode pair shunts transients to rails before reaching precision op-amps or ADC inputs. Use Value: Provides 30 V standoff and sub-ns response to protect 24 V sensor supplies and 3.3 V signal chains simultaneously. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-series Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSR20F30HT1G | Single Schottky diode (not dual-series); VF = 450 mV @ 10 mA; same SOT-23 package | Lacks built-in series configuration - requires external series routing for equivalent clamping topology | Select only if discrete layout control is preferred and board area permits added trace routing |
| Vishay VS-2EDH01-M3/84A | Dual common-cathode Schottky (not series); VR = 40 V; VF = 490 mV @ 10 mA; SOD-323 package | Supports parallel channel operation but cannot replicate series-clamp function without redesign | Prefer for dual-rail independent protection; avoid when series-path clamping is mandatory |
Compared with NSR20F30HT1G and VS-2EDH01-M3/84A, the 1PS70SB14 uniquely provides monolithic series-diode topology in SC-70, eliminating interconnect inductance and ensuring matched thermal behavior - critical for high-frequency clamping where timing skew between diodes degrades performance.

FAQ
What is the maximum continuous forward current per diode in the 1PS70SB14?
The 1PS70SB14 supports 200 mA continuous forward current per diode at Tamb < 25 °C. Derating is required above ambient temperature - for example, at 85 °C ambient, maximum continuous current drops to approximately 120 mA based on its 200 mW total power dissipation limit and 625 K/W thermal resistance.
Can the 1PS70SB14 be used for bidirectional ESD protection?
No - the 1PS70SB14 is configured as two Schottky diodes in series (A1–K1/A2–K2), forming a unidirectional conduction path from Pin 1 to Pin 2. For bidirectional ESD clamping, a dual-common-anode or dual-common-cathode arrangement would be required; this device functions as a series-blocking or forward-clamping element only.
Is the shared terminal (Pin 3) electrically accessible on the PCB?
No - Pin 3 (K1/A2) is the internal series junction between the two Schottky diodes and is not bonded to an external lead. It is fully encapsulated within the SOT323 package and has no PCB pad or solder land; only Pins 1 and 2 are externally routed and usable in circuit design.
How does the guard ring improve reliability in automotive environments?
The integrated guard ring reduces electric field crowding at the diode junction edge during high-voltage transients, suppressing premature avalanche and improving resistance to repetitive ESD pulses (e.g., ISO 10605) and load-dump surges. This directly extends operational lifetime in under-hood ECUs exposed to harsh thermal cycling and electrical noise.
