Product details
Overview
BAS70-04 from Nexperia is a general-purpose dual Schottky diode in SOT23 package, configured as two independent diodes sharing a common terminal (anode 1 / cathode 2 / cathode 1–anode 2). It delivers 70 V reverse voltage rating, 70 mA forward current capability, and 410 mV typical forward voltage at 1 mA - enabling ultra-high-speed switching and low-loss clamping in compact DC-DC feedback paths and signal line protection.
For engineers reviewing the BAS70-04 datasheet, BAS70-04 pinout, BAS70-04 application, or BAS70-04 equivalent, key selection criteria include its dual-diode topology with shared terminal, low 2 pF capacitance at 0 V, 100 nA reverse leakage at 50 V, and thermal resistance of 500 K/W on FR4 - critical for high-frequency rectification and rail-to-rail clamping in space-constrained designs.
Technical Context
The BAS70-04 integrates two discrete Schottky junctions in a single SOT23-3 package with a shared-terminal configuration: Pin 1 = Anode 1, Pin 2 = Cathode 2, Pin 3 = Cathode 1 / Anode 2. This arrangement supports series-connected or common-cathode/anode configurations without external wiring.
Its Schottky architecture enables sub-10 ns switching, while low 2 pF capacitance and 100 nA IR at 50 V support stable operation in RF detector inputs and fast transient clamp circuits where parasitic capacitance and leakage directly impact signal fidelity and quiescent power.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 70 V - supports clamping up to 70 V rails without breakdown in overvoltage protection circuits. |
| Forward Current (IF) | 70 mA continuous - sufficient for biasing, level-shifting, and low-power signal routing applications. |
| Forward Voltage (VF) | 410 mV @ 1 mA - minimizes conduction loss in low-current sensing and logic-level translation paths. |
| Reverse Leakage (IR) | 100 nA @ 50 V - ensures negligible standby current in battery-backed or energy-harvesting signal paths. |
| Capacitance (Cd) | 2 pF @ 0 V, 1 MHz - preserves signal integrity in >100 MHz detector and sampling circuits. |
| Junction Temp (Tj) | 150 °C max - allows reliable operation in thermally dense PCB layouts near power stages. |
Pinout & Package
Package: SOT23 (TO-236AB), 3-terminal surface-mount plastic package, 2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode 1 | Input node for first Schottky path; connects to source/positive rail in clamping or OR-ing configurations. |
| 2 | Cathode of Diode 2 | Output node for second Schottky path; used for bidirectional signal steering or dual-rail detection. |
| 3 | Cathode of Diode 1 / Anode of Diode 2 | Shared terminal enabling compact dual-diode topologies - eliminates need for external interconnect in common-cathode or series arrangements. |
Key Features
| Feature | Design Value |
|---|---|
| High switching speed | Sub-10 ns recovery enables use in >100 MHz RF detector and pulse-clamp circuits without distortion. |
| Low leakage current | 100 nA @ 50 V ensures <1 µW standby dissipation in always-on sensor interfaces and battery monitors. |
| Low capacitance | 2 pF @ 0 V maintains >500 MHz small-signal bandwidth in high-frequency sampling and mixer LO injection paths. |
| High breakdown voltage | 70 V VR rating supports direct integration into 48 V telecom bias supplies and industrial 24–48 V I/O protection. |
Applications
| RF Signal Detector | DC-DC Feedback Clamp |
|---|---|
Use Scenario: Detecting and rectifying weak RF signals in 2.4 GHz ISM-band receivers. IC Role / Device Role / Timing Role: Schottky diode pair acting as zero-bias envelope detector with minimal junction capacitance. Use Value: 2 pF capacitance and 410 mV VF preserve sensitivity and dynamic range without requiring external bias networks. |
Use Scenario: Clamping feedback voltage in isolated flyback converters to prevent regulation overshoot during load transients. IC Role / Device Role / Timing Role: Dual-diode clamp limiting error amplifier input swing to ±0.7 V. Use Value: Shared-terminal pinout allows compact placement adjacent to optocoupler input, reducing parasitic inductance in high-dV/dt environments. |
| Logic-Level Translator | ESD Protection Diode Array |
Use Scenario: Level-shifting between 3.3 V microcontroller GPIO and 5 V peripheral interface lines. IC Role / Device Role / Timing Role: Bidirectional clamping diode pair referenced to separate supply rails. Use Value: Low 410 mV VF ensures minimal voltage drop and fast edge propagation (<2 ns delay) across translation paths. |
Use Scenario: Protecting USB 2.0 D+/D− lines against ±8 kV contact ESD per IEC 61000-4-2. IC Role / Device Role / Timing Role: Dual-path low-capacitance shunt clamp to ground and VBUS. Use Value: 2 pF capacitance avoids signal integrity degradation at 480 Mbps data rates while maintaining <100 nA leakage at 3.3 V. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2004LK3-7 | Single-channel MOSFET-based load switch; no diode function; 20 V max rating. | Not suitable for clamping or RF detection; intended for power sequencing only. | Select only if replacing discrete diodes with active control is required and voltage rating permits. |
| BAT54C,215 | Dual Schottky in SOT23 with common-cathode (not shared-terminal) pinout; 30 V VR; 240 mV VF @ 10 mA. | Better low-VF performance at higher currents but lower voltage margin; incompatible pin mapping. | Prefer for 3.3/5 V systems needing lower conduction loss; avoid when 70 V clamping or shared-terminal topology is essential. |
Compared with BAT54C,215, the BAS70-04 provides 2.3× higher reverse voltage margin and unique shared-terminal flexibility for custom dual-diode routing, while BAT54C offers lower VF at ≥10 mA but requires redesign of PCB layout and circuit topology.

FAQ
What is the pin configuration of the BAS70-04?
Pin 1 is Anode 1, Pin 2 is Cathode 2, and Pin 3 serves as both Cathode 1 and Anode 2 - forming a shared-terminal dual-diode structure. This configuration enables compact implementation of series, common-anode, or common-cathode topologies without external traces, verified in Nexperia's official SOT23 outline and pinning table.
Can BAS70-04 be used in 48 V power supply circuits?
Yes - its 70 V reverse voltage rating exceeds 48 V system requirements, and its 70 mA forward current supports auxiliary bias and feedback clamping functions. Thermal resistance of 500 K/W on FR4 ensures safe operation at ambient temperatures up to 125 °C when derated per Nexperia's limiting values table.
How does BAS70-04 compare to BAT54 series in layout compatibility?
BAS70-04 uses a shared-terminal pinout (A1/K2/K1–A2), whereas BAT54C has a common-cathode arrangement (K/K/A). They are not footprint-compatible: BAS70-04 requires dedicated SOT23 land pattern per Figure 6 in its datasheet, and swapping without PCB revision will cause functional failure.
Is BAS70-04 qualified for automotive applications?
No - the January 2023 datasheet explicitly states this part is non-automotive qualified and superseded prior automotive variants. For automotive use, Nexperia recommends its -Q qualified alternatives such as BAS70-04-Q, which undergo extended temperature testing and AEC-Q101 stress validation.
