Product details
Overview
BAS70-06B5003 from Infineon Technologies is a dual common-anode silicon Schottky diode in SOT23 package, rated for 70 V reverse voltage and 70 mA continuous forward current, with low forward voltage (600 mV typ. at 10 mA) and ultrafast recovery time (≤100 ps), used in high-speed switching and voltage clamping circuits in consumer power management.
For engineers reviewing the BAS70-06B5003 datasheet, BAS70-06B5003 pinout, BAS70-06B5003 application, or BAS70-06B5003 equivalent, key selection criteria include VF matching (≤20 mV max ΔVF), low CT (1.5 pF typ. at 0 V), thermal resistance (RthJS ≤ 195 K/W), and SOT23-compatible layout for space-constrained DC-DC feedback paths and signal-level protection.
Technical Context
This dual-diode configuration shares a common anode (Pin 1), with cathodes on Pins 2 and 3, enabling independent clamping or steering functions in compact layouts. Its Schottky barrier construction eliminates minority-carrier storage, delivering sub-100 ps reverse recovery and minimal switching loss.
The device operates across –55 °C to +125 °C, supported by low thermal resistance (≤195 K/W junction-to-soldering-point) and stable VF over temperature (300–1000 mV range at IF = 1–15 mA), making it suitable for ambient-variable industrial signal conditioning and low-power RF detector stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 70 V - supports clamping in 48 V and 24 V rail protection without breakdown |
| Forward Current (IF) | 70 mA - sufficient for biasing, level-shifting, and low-current detection circuits |
| Forward Voltage (VF) | 600 mV typ. @ 10 mA - reduces conduction loss and self-heating in battery-powered signal paths |
| Diode Capacitance (CT) | 1.5 pF typ. @ 0 V, 1 MHz - preserves high-frequency integrity in RF mixer and detector nodes |
| Reverse Recovery Time (τrr) | ≤100 ps - enables clean switching up to ~1 GHz without tail current or ringing |
| Thermal Resistance (RthJS) | ≤195 K/W - allows sustained operation at TS ≤ 101 °C under 250 mW dissipation |
| VF Matching (ΔVF) | ≤20 mV @ 10 mA - ensures balanced current sharing in dual-path sensing or redundancy circuits |
Pinout & Package
SOT23-3 plastic surface-mount package with gull-wing leads; standardized footprint per Infineon outline drawing (pin pitch 0.95 mm, body size 2.9 × 1.3 × 1.0 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Common Anode | Shared positive terminal for both diodes; connects to supply or bias node |
| Pin 2 | Cathode 1 | Output/switching node for first diode path; routed to clamp or steer target net |
| Pin 3 | Cathode 2 | Independent output node for second diode path; enables dual-rail or differential clamping |
Key Features
| Feature | Design Value |
|---|---|
| Dual common-anode topology | Reduces PCB area vs. two discrete SOT23 diodes; simplifies routing in feedback and protection nets |
| Ultra-low reverse recovery charge | Enables zero-crossing switching in high-frequency rectifier and snubber applications without oscillation |
| Low thermal resistance (RthJS ≤ 195 K/W) | Permits higher ambient operation in sealed enclosures without derating beyond 70 mA |
| Matched VF (≤20 mV ΔVF) | Supports precision dual-path current sensing or balanced signal limiting without calibration |
Applications
| Power Rail Clamping | RF Signal Detection |
|---|---|
Use Scenario: Protecting 3.3 V and 5 V microcontroller I/O pins from ESD-induced voltage spikes during hot-plug events. IC Role / Device Role: Fast clamping diode shunting transient energy to ground before IC damage threshold is exceeded. Use Value: Sub-100 ps τrr and 0.6 V VF ensure clamping activates within one nanosecond, limiting overshoot to <5.5 V. | Use Scenario: Demodulating AM signals in low-power IoT sensor transceivers operating at 433 MHz. IC Role / Device Role: Passive envelope detector converting RF carrier amplitude to baseband voltage. Use Value: 1.5 pF CT and matched VF enable accurate low-distortion detection with minimal loading of tank circuit. |
| DC-DC Feedback Path | Logic-Level Translation |
Use Scenario: Isolating feedback voltage from secondary-side error amplifier in isolated flyback converters. IC Role / Device Role: Bidirectional voltage limiter preventing op-amp saturation during startup or fault conditions. Use Value: Common-anode configuration allows single-device bidirectional clamping between FB and COMP pins. | Use Scenario: Level-shifting UART signals between 1.8 V MCU and 3.3 V peripheral in wearables. IC Role / Device Role: Passive OR-ing diode enabling safe bidirectional logic translation without active drivers. Use Value: ≤20 mV VF mismatch ensures consistent threshold across both signal directions, minimizing timing skew. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSR0230HT1G | Single diode, SOD-123, 30 V VR, 200 mA IF - higher current but lower voltage rating | Not pin-compatible; requires two devices for dual function; unsuitable for >40 V clamping | Select only when higher IF and lower VF (370 mV @ 10 mA) outweigh need for dual integration |
| BAT54C | Dual common-cathode SOT23, 30 V VR, 200 mA IF - opposite polarity and lower VR rating | Requires board redesign (cathode-common vs. anode-common); incompatible in existing clamp topologies | Choose only if system uses cathode-referenced clamping and VR ≤ 30 V is acceptable |
Compared with NSR0230HT1G and BAT54C, BAS70-06B5003 uniquely delivers 70 V capability in a common-anode dual configuration with sub-100 ps recovery-critical for high-voltage, high-frequency protection where layout density and polarity alignment constrain alternatives.

FAQ
What is the maximum junction temperature for BAS70-06B5003?
The absolute maximum junction temperature (Tj) is 150 °C, validated per Infineon's datasheet revision 2006-02-01. Operation above this limit risks permanent degradation of the Schottky barrier and increased leakage. Derating begins at TS = 101 °C, where total power dissipation must be limited to 250 mW.
Is BAS70-06B5003 qualified for automotive use?
No - the datasheet explicitly states "Not for automotive applications" and notes that automotive qualification was "ongoing" as of 2006-08-04. It lacks AEC-Q101 certification and is intended for industrial, consumer, and computing applications only.
How does the common-anode configuration affect PCB layout?
The common-anode (Pin 1) simplifies routing in clamping applications where both cathodes connect to separate nets needing protection to the same rail. It eliminates the need for a shared trace to two discrete anodes, reducing parasitic inductance and improving high-frequency transient response.
Can BAS70-06B5003 replace BAS70-04 in the same footprint?
Yes - both share identical SOT23-3 packaging and pinout, but differ in internal configuration: BAS70-04 is common-cathode, while BAS70-06 is common-anode. Replacement requires verifying circuit topology compatibility; swapping without schematic review may invert clamping polarity or disable functionality.
