Product details
Overview
BAS70-05-QR from Nexperia is a general-purpose dual Schottky diode in SOT23 package, featuring 70 V reverse voltage rating, 70 mA forward current, 410 mV forward voltage at 1 mA, 2 pF capacitance at 0 V, and AEC-Q101 qualification for automotive use.
For engineers reviewing the BAS70-05-QR datasheet, BAS70-05-QR pinout, BAS70-05-QR application, or BAS70-05-QR equivalent, this device supports ultra-high-speed switching and voltage clamping where low VF, low IR, and fast recovery are critical in space-constrained PCB layouts.
Technical Context
The BAS70-05-QR integrates two independent Schottky diodes sharing a common cathode (pin 3), enabling compact dual-channel clamping or steering without discrete pairing. Its low 2 pF junction capacitance and sub-1 ns reverse recovery support >100 MHz signal integrity in RF front-ends and high-frequency power rail protection.
Thermal resistance of 500 K/W (junction-to-ambient, FR4 single-sided copper) and 150 °C max junction temperature allow operation in under-hood automotive environments. AEC-Q101 qualification confirms robustness against temperature cycling, humidity, and mechanical stress per automotive reliability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Reverse Voltage) | 70 V - Enables clamping of transients up to 70 V without breakdown in 12 V/24 V automotive systems. |
| VF (Forward Voltage) | 410 mV @ 1 mA - Minimizes conduction loss in low-current bias and sensing paths. |
| IR (Reverse Current) | 100 nA @ 50 V - Ensures negligible leakage in high-impedance voltage reference or sample-and-hold circuits. |
| Cd (Capacitance) | 2 pF @ 0 V, 1 MHz - Preserves signal edge fidelity in ESD protection and RF detector applications. |
| IF (Forward Current) | 70 mA continuous - Supports moderate-power logic-level clamping and level-shifting functions. |
| Tj (Junction Temp) | 150 °C - Allows sustained operation in engine control units and powertrain modules with ambient up to 125 °C. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-terminal, 1.9 mm pitch, 2.9 mm × 1.3 mm × 1.0 mm body, optimized for reflow and wave soldering per IPC-7351B footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (Diode 1) | Input node for first Schottky path; used for signal steering or rail clamping in channel A. |
| 2 | Anode (Diode 2) | Independent input node for second Schottky path; enables dual-rail or differential clamping. |
| 3 | Common Cathode | Shared output node; simplifies PCB routing and reduces trace inductance in parallel configurations. |
Key Features
| Feature | Design Value |
|---|---|
| High Switching Speed | Sub-1 ns reverse recovery time - Critical for minimizing pulse distortion in digital signal conditioning and transient suppression. |
| Low Leakage Current | 100 nA @ 50 V - Maintains accuracy in precision analog monitoring and battery-backed circuits. |
| AEC-Q101 Qualified | Validated for automotive grade-1 (−40 °C to +125 °C ambient) - Meets OEM requirements for under-hood electronics. |
| Low Capacitance | 2 pF - Reduces loading on high-frequency clock lines and RF antenna matching networks. |
Applications
| Automotive CAN Bus Protection | USB Port ESD Clamping |
|---|---|
Use Scenario: Protecting CAN_H/CAN_L lines from ISO 7637-2 load dump and ESD events in vehicle ECUs. IC Role / Device Role / Timing Role: Dual Schottky clamping diode providing bidirectional transient suppression with minimal signal delay. Use Value: 70 V VR withstands 24 V system load dumps; 2 pF Cd avoids CAN bit timing skew at 1 Mbps. | Use Scenario: Safeguarding USB 2.0 D+/D− data lines against ±15 kV contact ESD per IEC 61000-4-2. IC Role / Device Role / Timing Role: Low-capacitance dual clamp shunting ESD current to ground while preserving signal integrity. Use Value: 410 mV VF ensures fast turn-on during ESD pulses; common cathode simplifies PCB layout. |
| DC-DC Converter Feedback Snubbing | Logic-Level Signal Steering |
Use Scenario: Snubbing feedback node transients in isolated flyback or buck-boost converters. IC Role / Device Role / Timing Role: Fast-recovery dual diode absorbing voltage spikes at optocoupler or error amplifier inputs. Use Value: 70 mA IF rating handles typical feedback current surges; 150 °C Tj supports high-density power designs. | Use Scenario: Routing multiple microcontroller GPIO signals to shared peripherals (e.g., I²C bus arbitration). IC Role / Device Role / Timing Role: OR-ing diode array enabling wired-AND logic with minimal forward drop. Use Value: 410 mV VF at 1 mA preserves logic high margin; SOT23 footprint saves board area vs. discrete diodes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSR0230HT1G | Single diode, SOD-123, 30 V VR, 200 mA IF - lower voltage rating, higher current, no common cathode. | Not suitable for dual-rail clamping; requires two devices for equivalent function. | Select only when single-diode topology and higher current are prioritized over dual integration. |
| Diodes Inc. BAV99WQ-7-F | Dual common-cathode Schottky, SOT-323, 70 V VR, 215 mA IF, 1.25 pF Cd - smaller package, higher IF, lower capacitance. | Higher current handling but tighter thermal limits due to smaller pad area; less robust for 150 °C junction operation. | Prefer for space-constrained consumer designs where peak current exceeds 70 mA and ambient < 85 °C. |
Compared with NSR0230HT1G and BAV99WQ-7-F, the BAS70-05-QR uniquely balances AEC-Q101 compliance, 70 V standoff, common-cathode dual integration, and 150 °C junction capability-making it optimal for automotive signal protection where reliability and layout efficiency are jointly critical.

FAQ
What is the maximum pulsed forward current rating for BAS70-05-QR?
The non-repetitive peak forward current (IFSM) is 100 mA for tp ≤ 10 ms at Tj(init) = 25 °C. This rating applies to short-duration surge events such as ESD-induced current spikes or inductive kickback, not continuous operation.
Does BAS70-05-QR support bidirectional clamping?
No-it is a dual unidirectional Schottky diode with anodes on pins 1 and 2 and a common cathode on pin 3. Bidirectional clamping requires external configuration (e.g., back-to-back placement) or a dedicated TVS device.
Can BAS70-05-QR be used in place of a single Schottky diode?
Yes, by connecting one anode (pin 1 or 2) and the common cathode (pin 3); the unused anode must be left floating or tied to a non-active potential. The electrical characteristics remain identical to those specified for the individual diode path.
Is the marking code "75%" on BAS70-05-QR consistent across production lots?
The "75%" marking denotes the type number; the "%" is a placeholder for the manufacturing site code (e.g., "75A" for one fab, "75B" for another). Site codes vary by lot but do not affect electrical or mechanical specifications.
