Product details
Overview
1PS70SB16 from Nexperia is a dual Schottky barrier diode in common-anode configuration, housed in an SOT323 (SC-70) package. It delivers 30 V reverse voltage rating, 200 mA forward current per diode, 400 mV forward voltage at 10 mA, 10 pF capacitance at 1 V, and AEC-Q101 qualification for automotive stress environments - used for ultra-high-speed switching and reverse polarity protection in compact power rails.
For engineers reviewing the 1PS70SB16 datasheet, 1PS70SB16 pinout, 1PS70SB16 application, or 1PS70SB16 equivalent, key selection criteria include low VF for efficiency-critical biasing, low Cd for high-frequency line termination, common-anode topology for dual-rail clamping, and AEC-Q101 validation for under-hood signal integrity.
Technical Context
This dual Schottky diode integrates a guard ring for ESD and transient stress protection while maintaining planar junction geometry. Its common-anode configuration enables simultaneous clamping of two independent signal or supply lines to a shared reference rail.
The device operates with junction temperatures up to 150 °C and exhibits thermal resistance of 625 K/W (junction-to-ambient, FR4 PCB, single-sided copper), supporting reliable operation in thermally constrained automotive and industrial PCB layouts without forced cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - supports 24 V automotive systems with 25 % margin against load-dump transients |
| Forward Current (IF) | 200 mA per diode - sufficient for low-power logic-level clamping and bias networks |
| Forward Voltage (VF) | 400 mV at 10 mA - minimizes conduction loss in always-on protection paths |
| Diode Capacitance (Cd) | 10 pF at 1 V, 1 MHz - enables clean termination of >100 MHz digital signals without resonance |
| Reverse Current (IR) | 2 µA at 25 V - ensures negligible leakage in battery-backed or low-quiescent circuits |
| Thermal Resistance (Rth(j-a)) | 625 K/W - defines maximum power dissipation (200 mW) on standard FR4 layout |
Pinout & Package
Package: SOT323 (SC-70), 3-pin surface-mount plastic package with 1.3 mm × 1.8 mm footprint and 0.95 mm height - optimized for space-constrained automotive ECUs and portable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (cathode of diode 1) | Output node for first Schottky path; connects to protected signal or rail |
| 2 | K2 (cathode of diode 2) | Output node for second independent Schottky path; enables dual-rail clamping |
| 3 | A1,A2 (common anode) | Shared anode tied to reference potential (e.g., VCC or ground); defines clamping threshold |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | 400 mV @ 10 mA - reduces voltage drop in reverse-polarity protection and level-shifting paths |
| Low capacitance | 10 pF @ 1 V - preserves signal integrity in USB 2.0, CAN FD, and LVDS termination |
| Common-anode dual configuration | Single-package dual clamping - eliminates discrete pairing and layout mismatch in differential or dual-supply systems |
| AEC-Q101 qualification | Stress-tested for automotive temperature cycling, humidity, and mechanical shock - validated for engine control and body electronics |
Applications
| Automotive Body Control Module (BCM) | USB 2.0 Data Line Protection |
|---|---|
Use Scenario: Protecting LIN bus and sensor inputs from reverse battery connection and load-dump spikes in door modules and lighting controllers. IC Role / Device Role / Timing Role: Dual Schottky clamp - cathodes connected to protected lines, common anode tied to 12 V rail for positive clamping and reverse polarity blocking. Use Value: Prevents latch-up and damage during jump-start events while adding <1 ns propagation delay due to low Cd and VF. | Use Scenario: Clamping D+ and D− lines to VDD and GND in portable USB peripherals to suppress ESD and overshoot. IC Role / Device Role / Timing Role: Dual-line bidirectional clamp - each cathode tied to a data line, common anode to VDD for overvoltage protection and to GND via second device for undershoot suppression. Use Value: Meets IEC 61000-4-2 Level 4 (±15 kV air) without external TVS, leveraging 10 pF Cd to avoid signal distortion. |
| Industrial PLC Digital Input Stage | DC-DC Converter Feedback Path Protection |
Use Scenario: Isolating 24 V digital input channels from field wiring faults and induced transients in factory automation I/O modules. IC Role / Device Role / Timing Role: Input line clamp - cathodes connected to channel inputs, common anode tied to 24 V supply to limit negative excursions and absorb inductive kickback. Use Value: Enables robust 30 V-rated protection in sub-2 mm² area, reducing BOM count versus discrete diode pairs. | Use Scenario: Shielding optocoupler feedback pins in isolated flyback converters from output overvoltage and cross-regulation disturbances. IC Role / Device Role / Timing Role: Precision clamp - cathodes connected to FB and COMP nodes, common anode tied to reference voltage to prevent controller saturation during fault conditions. Use Value: Maintains regulation accuracy with <0.5 % error shift due to 400 mV VF stability across -40 to 125 °C. |
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 NSR20F30NXT5G | 30 V VR, 200 mA IF, VF = 450 mV @ 10 mA, SOT-323 package, AEC-Q101 qualified | Slightly higher VF increases conduction loss in always-on paths; identical pinout and thermal profile | Select when sourcing diversification is required and 50 mV VF penalty is acceptable for cost or lead-time reasons |
| Vishay VS-2EDH01HM3/85A | 30 V VR, 200 mA IF, VF = 390 mV @ 10 mA, SOT-323, AEC-Q101 qualified, lower Cd = 8 pF | Better high-frequency performance due to reduced capacitance; tighter VF distribution improves matching in dual-path designs | Prefer for USB 3.0 auxiliary lines or RF front-end bias networks where sub-10 pF is critical |
Compared with NSR20F30NXT5G and VS-2EDH01HM3/85A, the 1PS70SB16 offers balanced VF/Cd trade-off and broad automotive qualification history, making it optimal for cost-sensitive, thermally constrained BCM and PLC input stages where 10 pF and 400 mV meet system margins.

FAQ
Is the 1PS70SB16 suitable for reverse polarity protection in 24 V automotive systems?
Yes. With a 30 V reverse voltage rating and AEC-Q101 qualification, the 1PS70SB16 withstands typical 24 V system transients including ISO 7637-2 pulse 1 (−150 V, 2 Ω) when used with appropriate series impedance. Its 400 mV forward voltage ensures minimal voltage drop during normal operation, preserving headroom for downstream regulators.
What is the maximum continuous power dissipation for the 1PS70SB16 on a standard PCB?
The 1PS70SB16 has a total power dissipation limit of 200 mW at Tamb < 25 °C. With Rth(j-a) = 625 K/W on FR4 (single-sided copper), junction temperature rises ~125 °C per watt - so at 200 mW, ΔTj ≈ 125 °C, reaching the 150 °C max Tj only near ambient extremes. Derating is required above 25 °C ambient.
Can the 1PS70SB16 be used for high-speed data line termination?
Yes. Its 10 pF capacitance at 1 V and 1 ns typical reverse recovery time enable clean termination of signals up to 200 MHz. It is widely deployed in USB 2.0, CAN, and RS-485 interfaces where low Cd prevents signal ringing and maintains eye diagram integrity without requiring additional RC damping.
Does the common-anode configuration support independent cathode routing?
Yes. Pins 1 and 2 are electrically isolated cathodes (K1 and K2), allowing separate connection to distinct signal lines or rails. The shared anode (Pin 3) must be connected to a single reference potential - enabling coordinated clamping action while preserving functional independence between the two diode paths.
