Product details
Overview
BAS70-05B5003 from Infineon Technologies is a silicon Schottky diode in SOT23 package configured as common anode dual diode, rated for 70 V reverse voltage, 70 mA forward current, and 250 mW total power dissipation at TS ≤ 95 °C, used for high-speed switching and voltage clamping in signal path protection circuits.
For engineers reviewing the BAS70-05B5003 datasheet, BAS70-05B5003 pinout, BAS70-05B5003 application, or BAS70-05B5003 equivalent, key selection criteria include VF matching (≤20 mV at IF = 10 mA), low CT (1.5–2 pF @ VR = 0 V, f = 1 MHz), fast τrr (≤100 ps), thermal resistance RthJS ≤ 220 K/W, and SOT23 common-anode layout for compact dual-diode routing.
Technical Context
This dual Schottky diode integrates two anode-connected junctions in a single SOT23 footprint, enabling balanced clamping or steering functions without external node tying. Its low forward voltage (VF = 375–750 mV at IF = 10 mA) and minimal charge carrier lifetime (τrr ≤ 100 ps) support sub-nanosecond switching transitions in RF detector and high-frequency mixer stages.
The device exhibits tight VF matching (ΔVF ≤ 20 mV) between channels, critical for precision signal routing and differential sensing. Its thermal design targets TS ≤ 95 °C under full load, reflecting higher junction-to-solder-point resistance (RthJS ≤ 220 K/W) compared to single-diode variants like BAS70 (≤165 K/W).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 70 V - supports clamping of transient spikes up to 70 V without breakdown |
| Forward Current (IF) | 70 mA - continuous DC current handling per diode channel |
| Forward Voltage (VF) | 375–750 mV @ IF = 10 mA - enables low-loss signal steering with minimal voltage drop |
| Diode Capacitance (CT) | 1.5–2 pF @ VR = 0 V, f = 1 MHz - preserves high-frequency signal integrity above 500 MHz |
| Reverse Current (IR) | ≤ 0.1 µA @ VR = 50 V - ensures negligible leakage in high-impedance bias networks |
| Reverse Recovery Time (τrr) | ≤ 100 ps - allows operation in >1 GHz RF detection and mixing applications |
| Thermal Resistance (RthJS) | ≤ 220 K/W - defines maximum allowable power derating above ambient for TS-limited operation |
Pinout & Package
SOT23-3 package with standard JEDEC outline; 3-pin configuration where Pin 1 and Pin 2 are anodes, Pin 3 is common cathode. Marking "75s" identifies BAS70-05 variant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode 1 | Input node for first Schottky junction; tied internally to common cathode via low-VF junction |
| Pin 2 | Anode 2 | Independent input node for second junction; enables dual-path clamping or signal selection |
| Pin 3 | Common Cathode | Shared output terminal; simplifies PCB routing for bidirectional clamp or OR-ing configurations |
Key Features
| Feature | Design Value |
|---|---|
| Common-anode dual configuration | Enables compact, matched-pair clamping or signal steering without external interconnect |
| VF matching (ΔVF) | ≤20 mV at IF = 10 mA - ensures balanced conduction across both diodes for differential applications |
| Ultra-low reverse recovery time | τrr ≤ 100 ps - minimizes switching distortion in RF detector and mixer front-ends |
| Low diode capacitance | CT = 1.5–2 pF - maintains impedance stability and bandwidth in >500 MHz signal paths |
Applications
| RF Signal Detector | High-Speed Logic Clamp |
|---|---|
Use Scenario: Demodulating AM/ASK signals in 868 MHz ISM-band receivers using envelope detection. IC Role / Device Role / Timing Role: Dual-anode Schottky detector diode converting RF envelope to baseband DC voltage. Use Value: Low CT (1.5 pF) and fast τrr (≤100 ps) preserve modulation fidelity; matched VF ensures symmetric positive/negative half-cycle response. | Use Scenario: Protecting FPGA I/O pins from ESD-induced overvoltage during hot-plug events. IC Role / Device Role / Timing Role: Common-anode dual clamp limiting input swing to VCC + 0.3 V and GND − 0.3 V. Use Value: Sub-ns recovery and ≤0.1 µA IR prevent latch-up or false triggering while maintaining signal integrity at 100+ MHz data rates. |
| Dual-Path Signal Selector | Low-Voltage Level Shifter |
Use Scenario: Selecting between two analog sensor outputs (e.g., thermistor and photodiode) feeding a shared ADC input. IC Role / Device Role / Timing Role: Dual-anode steering diode routing active sensor signal while blocking idle channel. Use Value: Tight ΔVF (≤20 mV) ensures <0.5% gain error between paths; SOT23 footprint saves board space vs discrete diodes. | Use Scenario: Translating 1.8 V logic from a microcontroller to 3.3 V interface on a sensor hub PCB. IC Role / Device Role / Timing Role: Forward-biased Schottky diode shifting logic high level by ~0.4 V (VF ≈ 400 mV). Use Value: Predictable VF (375–750 mV @ 10 mA) enables accurate level translation without external resistors or active circuitry. |
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 (ON Semiconductor) | Single Schottky, 40 V VR, VF = 370 mV @ 1 mA, SOD-523 | Lacks dual configuration and common-anode topology; requires two devices for equivalent function | Choose when lower VR rating is acceptable and board area permits dual placement |
| NSR0230HT1G (onsemi) | Single Schottky, 30 V VR, VF = 420 mV @ 100 mA, SOD-123 | Higher IF rating but incompatible voltage range and no channel matching spec | Prefer only for cost-sensitive, non-matched, low-voltage (<30 V) clamping tasks |
Compared with RB751V-40T1G and NSR0230HT1G, BAS70-05B5003 uniquely delivers matched dual-channel performance in one SOT23 footprint-critical for RF detectors and differential clamps where timing skew and VF imbalance degrade system accuracy.

FAQ
What is the pin configuration of BAS70-05B5003?
BAS70-05B5003 uses a SOT23-3 package with Pin 1 and Pin 2 as independent anodes and Pin 3 as the common cathode. This common-anode arrangement is confirmed in Infineon's 2006 datasheet revision and matches the "75s" marking code. The layout enables dual-path signal routing without external node connection.
Does BAS70-05B5003 meet automotive qualification standards?
No-BAS70-05B5003 is explicitly marked "Not for automotive applications" in the original Infineon documentation. Although automotive qualification was noted as "ongoing" in 2006, no AEC-Q101 qualification status or automotive-grade part number (e.g., BAS70-05H) has been published or verified for this B5003 reel variant.
How does thermal resistance affect its power handling?
RthJS ≤ 220 K/W means that at TA = 25 °C, the junction temperature rises 220 K per watt dissipated. With Ptot = 250 mW and TS ≤ 95 °C, the maximum allowable ambient temperature before derating is approximately 39 °C-requiring careful thermal layout or power reduction above that point.
Can BAS70-05B5003 replace BAS70-05E6327?
Yes-BAS70-05B5003 and BAS70-05E6327 share identical electrical specs, SOT23 package, common-anode configuration, and "75s" marking. The difference lies only in packaging format (3k reel vs tape-and-reel variant) and date-code batch; no parametric or reliability divergence is documented.
