Product details
Overview
BAS70-05B5000 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 BAS70-05B5000 datasheet, BAS70-05B5000 pinout, BAS70-05B5000 application, or BAS70-05B5000 equivalent, key selection criteria include VF matching (≤20 mV at IF = 10 mA), low CT (1.5–2 pF at VR = 0 V, f = 1 MHz), fast τrr (≤100 ps), thermal resistance RthJS ≤ 220 K/W, and SOT23 footprint compatibility with space-constrained PCB layouts.
Technical Context
This dual-diode device integrates two Schottky junctions sharing a common anode terminal, enabling balanced clamping or steering functions in bidirectional signal conditioning. Its low forward voltage (VF = 375–705 mV typ. at IF = 10 mA) and minimal charge carrier lifetime (τrr ≤ 100 ps) support sub-nanosecond switching transitions.
The common-anode configuration allows simultaneous reverse-bias operation of both diodes when cathodes are driven independently, making it suitable for rail-to-rail input protection and precision detector front-ends where matched VF and low capacitance are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 70 V - supports clamping up to ±70 V transients without breakdown |
| Forward Current (IF) | 70 mA - continuous DC current handling per diode leg at TS ≤ 95 °C |
| Forward Voltage (VF) | 375–705 mV typ. at IF = 10 mA - enables low-loss signal rectification and biasing |
| Diode Capacitance (CT) | 1.5–2 pF at VR = 0 V, f = 1 MHz - minimizes signal distortion in RF/mixing applications |
| Reverse Current (IR) | ≤ 0.1 µA at VR = 50 V - ensures high isolation in sampling and hold circuits |
| Thermal Resistance (RthJS) | ≤ 220 K/W - limits junction temperature rise under sustained 70 mA load in SOT23 |
| Reverse Recovery Time (τrr) | ≤ 100 ps - supports >1 GHz small-signal switching in detector and mixer stages |
Pinout & Package
SOT23-3 package with gull-wing leads; standardized 2.4 mm × 1.3 mm footprint and 1.15 mm height; marking "75" on top surface per Infineon standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode (common) | Shared anode connection for both diodes; ties to positive supply or bias node |
| Pin 2 | Cathode 1 | First diode cathode; used for clamping or steering one signal path |
| Pin 3 | Cathode 2 | Second diode cathode; enables independent control or differential clamping |
Key Features
| Feature | Design Value |
|---|---|
| Common-anode dual configuration | Enables symmetrical clamping of complementary signals without external node tying |
| VF matching (ΔVF ≤ 20 mV) | Ensures consistent turn-on behavior across both diodes in precision detector applications |
| Low thermal resistance (RthJS ≤ 220 K/W) | Permits higher sustained current in thermally constrained SOT23 layouts |
| Sub-100 ps reverse recovery | Supports clean high-frequency signal routing in RF front-ends and sampling circuits |
Applications
| High-Speed Signal Clamping | RF Detector Front-End |
|---|---|
Use Scenario: Protecting ADC inputs from ESD-induced overvoltage during hot-plug events in industrial data acquisition systems. IC Role / Device Role / Timing Role: Dual Schottky clamp limiting input swing to ±0.7 V while preserving signal integrity below 100 MHz. Use Value: Prevents latch-up and damage using matched VF and <2 pF capacitance per diode leg. | Use Scenario: Demodulating AM signals in 868 MHz ISM-band receivers for smart metering nodes. IC Role / Device Role / Timing Role: Common-anode pair acting as envelope detector with minimal forward loss and fast recovery.

| Dual-Rail Input Protection | Precision Level Shifting |
Use Scenario: Safeguarding op-amp inputs in rail-to-rail sensor interfaces exposed to ±15 V transients. IC Role / Device Role / Timing Role: Cathodes tied to ±15 V rails; common anode connected to op-amp input for bidirectional clamping. Use Value: Leverages matched VF and low IR (<0.1 µA) to avoid DC offset drift during normal operation. | Use Scenario: Translating logic-level signals between 3.3 V microcontroller I/O and 5 V analog subsystems. IC Role / Device Role / Timing Role: One diode forward-biased to lift low-state voltage; second diode reverse-biased to block leakage. Use Value: Achieves <10 ns propagation delay and <20 mV VF mismatch for deterministic level shift accuracy. |
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, VF = 450 mV typ. @ 10 mA, CT = 2.5 pF | Requires two devices for dual function; larger footprint; no VF matching | Use only if board area permits discrete placement and matching is not required |
| BAT54C | Common-cathode dual, SOT23, VF = 350–600 mV @ 10 mA, CT = 10 pF | Higher capacitance degrades RF performance above 100 MHz; opposite polarity configuration | Select when common-cathode topology aligns with existing schematic and speed < 100 MHz suffices |
Compared with NSR0230HT1G and BAT54C, the BAS70-05B5000 uniquely delivers common-anode topology, sub-2 pF capacitance, and ≤20 mV VF matching-critical for high-frequency detector and matched-clamp designs where layout symmetry and timing consistency are non-negotiable.

FAQ
What is the maximum operating temperature for BAS70-05B5000?
The junction temperature limit is 150 °C, but the device must be operated within a soldering-point temperature (TS) of ≤95 °C to maintain its rated 250 mW power dissipation. Derating curves in the datasheet show usable forward current drops to ~60 mA at TS = 125 °C.
Is BAS70-05B5000 pin-compatible with BAS70-04 or BAS70-06?
Yes-BAS70-05B5000 shares the same SOT23-3 package and pinout (common anode at Pin 1), but differs in thermal design: BAS70-05 has lower max TS (95 °C vs. 101 °C for -04/-06), reflecting tighter thermal resistance (RthJS ≤ 220 K/W). Electrical specs are otherwise identical.
Does BAS70-05B5000 meet automotive qualification standards?
No-Infineon explicitly states this part is "not for automotive applications" and notes that automotive qualification was "ongoing" as of the 2006 datasheet edition. It lacks AEC-Q101 stress testing and is intended for industrial and commercial use only.
How is forward voltage matching measured in BAS70-05B5000?
ΔVF is defined as the difference between the lowest and highest measured forward voltage across the two diodes at IF = 10 mA, guaranteed ≤20 mV. This matching is verified per unit during production test and applies only to dual-diode configurations like BAS70-05, not single variants.
