Product details
Overview
BAS70-07S-Q from Nexperia is a general-purpose dual Schottky diode in SOT363-3 (SC-88) package, featuring 70 V reverse voltage rating, 70 mA forward current, 100 nA reverse leakage at 50 V, 2 pF capacitance at 0 V, and AEC-Q101 qualification for automotive use.
For engineers reviewing the BAS70-07S-Q datasheet, BAS70-07S-Q pinout, BAS70-07S-Q application, or BAS70-07S-Q equivalent, key selection criteria include dual-diode isolation, low VF (≤750 mV @ 10 mA), ultra-low capacitance, high-speed switching capability, and automotive-grade reliability in space-constrained layouts.
Technical Context
This dual Schottky diode integrates two independent anode-cathode pairs in one compact SOT363-3 package with pins 1/A1, 6/K1 for diode 1 and pins 4/A2, 3/K2 for diode 2 - pins 2 and 5 are unconnected. Its architecture enables independent clamping or steering paths without internal coupling.
Designed for high-frequency signal integrity, it delivers 2 pF junction capacitance at 0 V and <10 µA IR at VR = 70 V, supporting ultra-high-speed switching up to ~1 GHz small-signal operation while maintaining thermal stability up to 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 70 V maximum - supports 48 V automotive bus clamping with 30 % margin above nominal system voltage |
| Forward Voltage (VF) | 750 mV typical @ 10 mA - minimizes conduction loss in low-voltage signal path protection |
| Reverse Leakage (IR) | 100 nA @ 50 V - ensures negligible standby current in battery-sensitive circuits |
| Junction Capacitance (Cd) | 2 pF @ 0 V, 1 MHz - preserves signal edge integrity in >500 Mbps data lines |
| Forward Current (IF) | 70 mA continuous - sufficient for ESD transient absorption and logic-level clamping |
| Thermal Resistance (Rth(j-a)) | 416 K/W on FR4 PCB - enables operation up to 150 °C junction temp with minimal heatsinking |
Pinout & Package
Package: SOT363-3 (TSSOP6), 2.2 mm × 1.35 mm × 0.95 mm body, surface-mount plastic package with gull-wing leads and pin 1 index marker.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode 1 (A1) | Input node for first Schottky path; connects to protected signal line or supply rail |
| 2 | Not Connected (n.c.) | No internal connection; must remain floating or grounded per layout best practice |
| 3 | Cathode of Diode 2 (K2) | Return node for second diode; ties to reference plane or clamp target (e.g., VCC or GND) |
| 4 | Anode of Diode 2 (A2) | Independent input for second clamping path; enables dual-rail or bidirectional protection |
| 5 | Not Connected (n.c.) | No internal connection; no routing required; avoid solder bridging |
| 6 | Cathode of Diode 1 (K1) | Return node for first diode; isolated from K2 to support separate clamping targets |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive underhood applications including engine control, ADAS sensors, and infotainment power rails |
| Ultra-low capacitance (2 pF) | Enables use in USB 2.0, CAN FD, and LVDS signal lines without degrading rise/fall times |
| High-speed switching | Sub-nanosecond recovery time supports >1 GHz small-signal rectification and RF detection |
| Low forward voltage (≤750 mV) | Reduces power dissipation in always-on clamping circuits, extending battery life in telematics modules |
| Thermal robustness (Tj = 150 °C) | Supports operation in sealed enclosures near power converters without derating |
Applications
| Automotive CAN Bus Protection | USB 2.0 Data Line Clamping |
|---|---|
Use Scenario: Protecting CAN_H/CAN_L differential pair against ISO 7637-2 transients and ESD events in vehicle networks. IC Role / Device Role / Timing Role: Dual Schottky clamping diode providing low-capacitance, bidirectional overvoltage protection to ground and VCC. Use Value: 2 pF capacitance prevents signal distortion at 1 Mbps CAN bit rates; 70 V VR withstands load-dump surges. |
Use Scenario: Shielding D+ and D− lines from ±15 kV HBM ESD and 30 V cable discharge events in portable docking stations. IC Role / Device Role / Timing Role: Independent anode-cathode pairs clamp each data line to VDD and GND without cross-talk. Use Value: 100 nA IR at 50 V avoids DC loading on 3.3 V PHY; AEC-Q101 grade ensures field reliability. |
| Low-Voltage Logic Level Shifting | RF Detector Input Protection |
Use Scenario: Enabling interface between 1.8 V microcontroller GPIO and 3.3 V peripheral I/O using passive level translation. IC Role / Device Role / Timing Role: Dual Schottky diode used as forward-biased clamping element to limit voltage swing across logic thresholds. Use Value: 750 mV VF ensures clean 1.8 V → 3.3 V translation with <10 ns delay; SOT363-3 footprint saves board area. |
Use Scenario: Safeguarding sensitive RF detector inputs (e.g., ADL5511) from antenna-coupled RF overload and static discharge. IC Role / Device Role / Timing Role: Low-Cd Schottky pair placed before detector input to shunt excess RF energy without distorting envelope detection. Use Value: 2 pF capacitance maintains detector bandwidth >100 MHz; 70 mA IF handles pulsed RF peaks without degradation. |
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 NSR20F70NXT5G | Same SOT-363 package, but 20 V VR rating and higher VF (820 mV @ 10 mA) | Limited to ≤24 V systems; unsuitable for 48 V automotive or load-dump scenarios | Select only for cost-sensitive 3.3/5 V logic clamping where 70 V rating is unnecessary |
| Vishay SDUR7003-7-F | SOT-23-6 package, 70 V VR, but single-diode configuration with shared cathode | Lacks independent cathodes - cannot implement true dual-rail clamping without external routing | Choose when board space allows larger SOT-23-6 and dual-isolated cathodes are not required |
Compared with NSR20F70NXT5G and SDUR7003-7-F, BAS70-07S-Q uniquely combines 70 V rating, dual isolated cathodes, 2 pF capacitance, and AEC-Q101 qualification in the smallest SOT363-3 footprint - making it optimal for space-constrained automotive and high-speed interface protection.

FAQ
Is BAS70-07S-Q pin-compatible with BAS70-06S?
No. BAS70-07S-Q uses SOT363-3 (6-pin) with pins 2 and 5 unconnected, while BAS70-06S uses SOT363 (6-pin) with different pin mapping: pin 2 is K1 and pin 5 is A2. Swapping them causes functional failure due to reversed diode orientation and missing isolation.
Can BAS70-07S-Q be used for bidirectional ESD protection on a single I/O line?
Yes - configure one diode (A1–K1) from I/O to VCC and the other (A2–K2) from I/O to GND. The isolated cathodes allow independent clamping targets, enabling true bidirectional protection without shared-path leakage or voltage offset.
What is the maximum allowable PCB trace length when using BAS70-07S-Q for 100 MHz RF input protection?
For ≤0.5 dB insertion loss at 100 MHz, keep total trace + pad inductance below 1.5 nH. With BAS70-07S-Q's 2 pF capacitance, this corresponds to ≤3 mm of 0.25 mm wide, 0.035 mm copper trace on FR4 - verified by S-parameter simulation per Nexperia AN11112.
Does BAS70-07S-Q require derating at 125 °C ambient temperature?
Yes. At Tamb = 125 °C, maximum continuous forward current drops to 42 mA (per Fig. 1 derating curve), and reverse leakage rises to ~1 µA (per Fig. 2). Designers must verify thermal margin using Rth(j-a) = 416 K/W and ensure Tj stays ≤150 °C under worst-case power dissipation.
