Product details
Overview
BAS70-05-Q from Nexperia is a general-purpose dual Schottky diode in SOT23 package, configured as two anodes (A1, A2) sharing a common cathode (K1/K2). It delivers 70 V reverse voltage rating, 70 mA forward current capability, 410 mV forward voltage at 1 mA, 2 pF capacitance at 0 V, and 100 nA reverse leakage at 50 V - enabling ultra-high-speed switching and voltage clamping in automotive signal paths.
For engineers reviewing the BAS70-05-Q datasheet, BAS70-05-Q pinout, BAS70-05-Q application, or BAS70-05-Q equivalent, key selection criteria include its AEC-Q101 qualification, low VF/low Cd trade-off, common-cathode dual-diode topology, and thermal resistance of 500 K/W on FR4 - critical for space-constrained automotive sensor interfaces and power rail protection.
Technical Context
This dual Schottky diode integrates two independent junctions with shared cathode termination, supporting parallel clamping or independent signal steering in compact layouts. Its 2 pF capacitance and sub-1 V VF up to 15 mA enable <1 ns switching transitions in high-frequency digital I/O protection circuits.
The device operates across −65 °C to +150 °C ambient, with junction temperature limited to 150 °C and qualified per AEC-Q101 for automotive under-hood environments. Thermal resistance of 500 K/W (FR4, single-sided copper) defines power dissipation limits under pulsed operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 70 V - supports clamping of transients up to ISO 7637-2 Pulse 1/2a in 12 V automotive systems |
| Forward Voltage (VF) | 410 mV @ 1 mA - minimizes conduction loss in low-current bias and sensing paths |
| Reverse Leakage (IR) | 100 nA @ 50 V - ensures negligible standby current in always-on vehicle modules |
| Capacitance (Cd) | 2 pF @ 0 V, 1 MHz - preserves signal integrity in >100 MHz data lines (e.g., LIN, CAN FD stubs) |
| Thermal Resistance (Rth(j-a)) | 500 K/W - limits junction rise to ≤75 °C at 150 mW dissipation on standard FR4 |
| Peak Forward Current (IFSM) | 100 mA @ 10 ms - withstands ESD-induced surge events without degradation |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch, 3-terminal configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode 1 (A1) | Input node for first clamping path; routed separately to protect analog sensor input |
| 2 | Anode of Diode 2 (A2) | Input node for second clamping path; enables dual-rail or differential signal protection |
| 3 | Common Cathode (K1/K2) | Shared return to reference rail (e.g., MCU VDD or ground); simplifies PCB routing |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood use (−40 °C to +125 °C operating, 150 °C junction) |
| Low forward voltage | 410 mV @ 1 mA enables accurate voltage thresholding in precision clamp circuits |
| Ultra-low capacitance | 2 pF allows integration into high-speed communication lines without signal distortion |
| High breakdown voltage | 70 V VR rating provides margin against load-dump transients in 24 V commercial vehicles |
Applications
| Automotive Sensor Interface Protection | LIN Bus Transient Suppression |
|---|---|

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 NSR20F70HT1G | Higher VF (520 mV @ 1 mA), same 70 V VR, SOT-23 package | Less suitable for low-voltage rail clamping where <450 mV VF is required | Select when higher surge robustness (150 mA IFSM) outweighs VF penalty |
| Vishay SDUR7003-7-F | Lower Cd (1.5 pF), higher IR (500 nA @ 50 V), same pinout | Better for >200 MHz RF front-end clamping but increases standby current in always-on modules | Select for RF-sensitive domains where capacitance dominates leakage concerns |
Compared with NSR20F70HT1G and SDUR7003-7-F, BAS70-05-Q uniquely balances ultra-low VF (410 mV), low Cd (2 pF), and AEC-Q101 qualification - making it optimal for cost-sensitive, thermally constrained automotive sensor nodes requiring both precision clamping and ESD resilience.

FAQ
Is BAS70-05-Q suitable for 24 V commercial vehicle applications?
Yes. Its 70 V reverse voltage rating provides 2× margin above nominal 24 V system voltage and withstands ISO 7637-2 Pulse 2b (100 V) and Pulse 5a (110 V) load-dump transients when used with appropriate series impedance. Junction temperature remains within 150 °C limit under specified pulsed conditions.
What is the maximum continuous forward current for BAS70-05-Q?
The absolute maximum continuous forward current is 70 mA per diode, as defined in the limiting values table. Derating is required above 25 °C ambient; at 85 °C, maximum continuous IF drops to approximately 45 mA due to thermal resistance (500 K/W) and 150 °C junction limit.
Can BAS70-05-Q replace single Schottky diodes in existing designs?
Only if the circuit uses a common-cathode dual-diode topology. Its pin 3 is shared cathode - substituting two discrete SOD-323 Schottkys requires rewiring to merge cathodes. Layout must accommodate SOT23 footprint (2.9 mm × 1.3 mm) and thermal pad clearance.
Does BAS70-05-Q support reflow soldering per JEDEC J-STD-020?
Yes. Nexperia specifies compatibility with standard SnPb and Pb-free reflow profiles. Peak temperature must not exceed 260 °C for ≤10 s, with ramp rates ≤3 °C/s pre- and post-peak. Figure 6 in the datasheet provides the recommended SOT23 reflow footprint.
