Product details
Overview
BAS70-06W from Nexperia is a general-purpose dual Schottky diode in SOT323 (SC-70) package, featuring common-anode configuration, 70 V reverse voltage rating, 70 mA forward current capability, and 410 mV forward voltage at 1 mA - used for ultra high-speed switching and voltage clamping in compact power management and signal routing circuits.
For engineers reviewing the BAS70-06W datasheet, BAS70-06W pinout, BAS70-06W application, or BAS70-06W equivalent, key selection criteria include its dual-cathode/common-anode topology, low 2 pF capacitance at 0 V, 100 nA reverse leakage at 50 V, thermal resistance of 500 K/W, and suitability for space-constrained DC-DC feedback paths and logic-level clamping.
Technical Context
The BAS70-06W integrates two independent Schottky diodes sharing a single anode terminal, enabling compact dual-clamp or dual-switching functions in a 3-pin SOT323 footprint. Its low forward voltage and fast recovery support efficient operation in high-frequency switching regulators and level-shifting interfaces.
Designed for ambient temperatures from −65 °C to 150 °C and junction temperatures up to 150 °C, it delivers stable performance under pulsed conditions (tp ≤ 300 µs, duty cycle ≤ 0.02) with verified 100 mA non-repetitive peak forward current capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Voltage (VF) | 410 mV at 1 mA pulsed - enables low-loss biasing and clamping in low-voltage logic interfaces |
| Reverse Voltage (VR) | 70 V - supports use in 48 V industrial bus protection and 24 V DC-DC secondary-side snubbing |
| Forward Current (IF) | 70 mA continuous - sufficient for LED indicator drive and small-signal rectification |
| Diode Capacitance (Cd) | 2 pF at 0 V, 1 MHz - minimizes signal distortion in RF detector and high-speed data line clamping |
| Reverse Leakage (IR) | 100 nA at 50 V - ensures minimal quiescent current in battery-powered voltage reference circuits |
| Thermal Resistance (Rth(j-a)) | 500 K/W on FR4 PCB - defines derating curve for sustained operation in unheatsinked layouts |
Pinout & Package
Package: SOT323 (SC-70), 3-lead surface-mount plastic package, 2.0 mm × 1.25 mm × 0.95 mm body, 1.3 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Provides dedicated cathode path for first Schottky diode; routed separately for dual-clamp independence |
| 2 | Cathode (Diode 2) | Independent cathode node for second diode; enables differential or mirrored clamping configurations |
| 3 | Common Anode (A1/A2) | Shared anode connection - simplifies PCB layout for dual-diode functions without discrete wiring |
Key Features
| Feature | Design Value |
|---|---|
| High switching speed | Sub-nanosecond recovery enabled by Schottky barrier structure - critical for >100 MHz signal clamping |
| Low leakage current | 100 nA max at 50 V reverse bias - preserves accuracy in precision voltage reference and sensor bias networks |
| Low capacitance | 2 pF typical at zero bias - maintains signal integrity in USB 2.0, I²C, and CAN FD ESD protection paths |
| High breakdown voltage | 70 V VR rating - exceeds industrial 48 V rail transients and allows margin in 36 V automotive accessory designs |
Applications
| USB 2.0 Data Line Protection | DC-DC Converter Feedback Clamp |
|---|---|
|
Use Scenario: Clamping ESD transients on D+ and D− lines before USB PHY input. IC Role / Device Role / Timing Role: Dual-cathode Schottky clamp with shared anode tied to VBUS - provides symmetrical bidirectional clamping. Use Value: 2 pF capacitance avoids signal rise-time degradation; 410 mV VF ensures clamping threshold stays below 3.3 V logic tolerance. |
Use Scenario: Preventing op-amp saturation in isolated flyback feedback loop by limiting optocoupler LED current. IC Role / Device Role / Timing Role: Common-anode dual diode routes excess current from TL431 cathode to ground or reference via either cathode. Use Value: 70 mA IF rating handles transient overloads; low VF avoids false regulation during startup surges. |
| Logic-Level Voltage Translation | Low-Power Sensor Bias Network |
|
Use Scenario: Level-shifting between 1.8 V microcontroller GPIO and 3.3 V peripheral using passive diode-based translation. IC Role / Device Role / Timing Role: Dual diode provides matched forward characteristics for bidirectional translation paths. Use Value: Matched VF across both diodes (≤10 mV mismatch) ensures consistent high/low thresholds; SOT323 saves board area vs. discrete diodes. |
Use Scenario: Providing temperature-stable bias current to silicon photomultiplier (SiPM) anode while blocking reverse leakage. IC Role / Device Role / Timing Role: One diode supplies regulated bias; second blocks dark-current return path in multi-channel arrays. Use Value: 100 nA IR at 25 °C minimizes added noise; 150 °C Tj rating supports operation near heat-generating FPGAs. |
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 NSR20F70NXT5G | Higher IF (200 mA), higher VF (550 mV @ 1 mA), same SOT323 package and common-anode pinout | Better suited for higher-current clamping but increases voltage drop in low-VF-sensitive feedback loops | Select when surge current handling >100 mA is required and 140 mV higher VF is acceptable |
| Diodes Incorporated BAV99WQ-7-F | Lower VR (60 V), higher IR (500 nA @ 50 V), same pinout and package | Limited to ≤48 V systems; higher leakage may affect long-term stability in precision bias networks | Choose only for cost-sensitive consumer applications where 10 V VR margin and 400 nA extra leakage are tolerable |
Compared with NSR20F70NXT5G and BAV99WQ-7-F, the BAS70-06W offers the optimal balance of low VF, low Cd, and 70 V VR in a proven industrial-grade SOT323 package - making it preferred for space-constrained, low-noise, and medium-voltage clamping designs.

FAQ
Is BAS70-06W suitable for automotive applications?
No. The BAS70-06W is explicitly marked as non-automotive qualified in its revision history. It lacks AEC-Q101 qualification, has no automotive-grade screening, and is not tested to automotive temperature or reliability standards. For automotive use, Nexperia offers the BAS70-06W-Q variant with full AEC-Q101 compliance and extended qualification testing.
What is the maximum allowable soldering temperature profile for BAS70-06W?
The BAS70-06W supports standard lead-free reflow per J-STD-020, with peak temperature up to 260 °C for ≤30 seconds. Its SOT323 package requires a recommended reflow footprint (Fig. 6 in datasheet) with 0.55 mm solder paste stencil openings and 1.325 mm land width to ensure coplanarity and void-free joints.
Can BAS70-06W replace a single discrete Schottky diode in a circuit?
Yes, but only if the circuit uses only one of the two diodes and leaves the unused cathode floating or grounded - the common-anode configuration means both diodes share the same anode potential. Using only one diode does not degrade performance, though the second cathode must be properly terminated to avoid parasitic coupling.
How does BAS70-06W's thermal resistance compare to similar dual-diode packages?
At 500 K/W (junction-to-ambient, FR4 PCB, single-sided copper), BAS70-06W matches industry-standard SOT323 thermal performance. This is 15–20% higher than larger SOT23-3 dual diodes (~420 K/W) but remains adequate for ≤70 mA continuous operation without heatsinking in typical industrial ambient conditions.
