Product details
Overview
BAS70-07,215 from Nexperia is a general-purpose dual Schottky diode in SOT143B package, configured as two independent low-capacitance diodes with common cathode/anode pairing. It delivers 70 V reverse voltage rating, 410 mV forward voltage at 1 mA, and 2 pF capacitance at 0 V - enabling ultra-high-speed switching and voltage clamping in space-constrained signal paths.
For engineers reviewing the BAS70-07,215 datasheet, BAS70-07,215 pinout, BAS70-07,215 application, or BAS70-07,215 equivalent, key selection criteria include pulsed forward current capability (70 mA), low-leakage performance (100 nA at 50 V), thermal resistance (500 K/W), and dual-diode isolation for bidirectional clamping or level-shifting circuits.
Technical Context
This dual Schottky diode integrates two independent junctions in a single SOT143B package, with pin 1 (K1) and pin 2 (K2) serving as separate cathodes, and pins 4 (A1) and 3 (A2) as corresponding anodes. Its architecture supports independent biasing of each diode without internal connection between them.
Designed for high-frequency operation, it exhibits 2 pF junction capacitance at 0 V and 1 MHz, 10 µA max reverse leakage at 70 V, and differential forward resistance below 1 Ω at 10 mA - making it suitable for RF detector inputs, ESD protection clamps, and fast logic-level translation where low stored charge is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 70 V - supports clamping in 48 V telecom and 3.3–5 V logic interfaces without breakdown. |
| Forward Voltage (VF) | 410 mV at 1 mA - minimizes conduction loss in low-current sensing and bias networks. |
| Junction Capacitance (Cd) | 2 pF at 0 V, 1 MHz - preserves signal integrity in >500 MHz RF front-end and high-speed data lines. |
| Reverse Leakage (IR) | 100 nA at 50 V - ensures stable DC bias in precision analog sample-hold and reference circuits. |
| Thermal Resistance (Rth(j-a)) | 500 K/W - requires minimal PCB copper area for thermal management in ambient ≤85 °C environments. |
| Peak Forward Current (IFSM) | 100 mA (10 ms pulse) - handles transient overvoltage events in I/O protection applications. |
Pinout & Package
SOT143B surface-mount plastic package: 4-lead, 1.9 mm pitch, 2.9 × 1.3 × 1.0 mm body, optimized for reflow soldering on FR4 PCBs with standard footprint per Figure 6.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K1) | Cathode of Diode 1 | Reference node for first Schottky junction; connects to ground or lower-potential rail in clamp configuration. |
| 2 (K2) | Cathode of Diode 2 | Independent cathode for second junction; enables dual-rail clamping or differential signal routing. |
| 3 (A2) | Anode of Diode 2 | Input terminal for second diode; used for reverse-biased clamping or forward-biased rectification path. |
| 4 (A1) | Anode of Diode 1 | Primary input for first diode; commonly tied to signal line requiring fast turn-on and low VF response. |
Key Features
| Feature | Design Value |
|---|---|
| High switching speed | Sub-nanosecond recovery due to Schottky barrier structure - avoids minority-carrier storage delay in GHz-range signals. |
| Low leakage current | 100 nA at 50 V - maintains accuracy in high-impedance feedback networks and battery-monitoring dividers. |
| High breakdown voltage | 70 V VR rating - exceeds industrial 48 V bus and automotive 36 V transients without avalanche conduction. |
| Low capacitance | 2 pF at zero bias - reduces loading on high-Z nodes in RF mixers, crystal oscillator buffers, and ADC front-ends. |
Applications
| USB 2.0 Data Line Protection | RF Detector Input Clamp |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB751V-40T1G | Single diode, SOD-523, 40 V VR, 370 mV VF @ 1 mA | Lacks dual configuration; requires two devices for same functionality | Choose when board space permits discrete placement and lower VR suffices. |
| BAT54C,215 | Dual common-cathode Schottky, SOT-23, 30 V VR, 240 mV VF @ 10 mA | Lower VR and higher VF limit use in 48 V systems and precision low-VF paths | Prefer for cost-sensitive 3.3/5 V logic clamping where 30 V margin is adequate. |
Compared with RB751V-40T1G and BAT54C,215, the BAS70-07,215 uniquely combines 70 V standoff, dual independent terminals, and sub-2 pF capacitance - making it the only option among the three qualified for 48 V telecom surge protection and GHz RF signal path clamping.

FAQ
What is the maximum continuous forward current for BAS70-07,215?
The absolute maximum continuous forward current is 70 mA per diode, as specified in the Limiting Values table under IF. This rating applies at Tamb = 25 °C with free-air convection; derating is required above 25 °C ambient per the thermal resistance of 500 K/W.
Can BAS70-07,215 be used in automotive applications?
No - the 2023 datasheet explicitly states this part is non-automotive qualified. It lacks AEC-Q101 stress testing and qualification. For automotive use, Nexperia offers the -Q qualified variants such as BAS70-07W-Q, which undergo extended temperature cycling and humidity testing.
How does the SOT143B package affect PCB layout for high-frequency use?
The SOT143B's 1.9 mm lead pitch and 2.9 × 1.3 mm footprint enable tight trace routing with minimized loop inductance. Its symmetrical pinout (K1-A1-K2-A2) supports balanced differential clamping layouts, and the recommended reflow footprint in Figure 6 ensures reliable solder joint formation without tombstoning.
Is the forward voltage matched between the two diodes in BAS70-07,215?
Yes - characterization curves in Figures 1 and 2 show overlapping VF vs. IF traces for both diodes across −40 °C to 125 °C, confirming matched behavior. Typical VF spread is <20 mV at 1 mA, verified by Nexperia's production binning and process control for dual-die monolithic construction.
