Product details
Overview
BAS70-05 from Nexperia is a general-purpose dual Schottky diode in SOT23 package, configured as two anodes (A1, A2) sharing a common cathode (K1/K2). It delivers 70 V reverse voltage rating, 70 mA forward current capability, and 410 mV typical forward voltage at 1 mA, enabling ultra-high-speed switching and low-loss clamping in compact power management and signal routing circuits.
For engineers reviewing the BAS70-05 datasheet, BAS70-05 pinout, BAS70-05 application, or BAS70-05 equivalent, key selection criteria include its dual-anode/common-cathode topology, 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 BAS70-05 integrates two independent Schottky junctions in a single SOT23-3 package with shared cathode termination, supporting parallel or independent anode routing. Its low forward voltage (≤750 mV at 10 mA) and minimal junction capacitance (2 pF) enable fast transient response in high-frequency clamp and steering applications.
Thermal performance is defined by a junction-to-ambient thermal resistance of 500 K/W on standard FR4 PCB, with absolute maximum junction temperature of 150 °C and storage/ambient range spanning −65 °C to +150 °C - confirming robustness for industrial ambient conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 70 V - supports clamping in 48 V and 36 V supply rails without breakdown |
| Forward Current (IF) | 70 mA continuous - sufficient for biasing, level-shifting, and low-power signal path protection |
| Forward Voltage (VF) | 410 mV at 1 mA - minimizes conduction loss in low-current sensing and reference paths |
| Reverse Leakage (IR) | 100 nA at 50 V - ensures negligible standby current in battery-backed or energy-harvesting circuits |
| Capacitance (Cd) | 2 pF at 0 V - preserves signal integrity up to ~100 MHz in RF detector or high-speed data line clamping |
| Thermal Resistance (Rth(j-a)) | 500 K/W - requires no heatsink on standard PCB; derating begins above ~85 °C ambient |
Pinout & Package
Package: SOT23 (TO-236AB), 3-terminal surface-mount plastic package, 2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode 1 (A1) | Input node for first Schottky path; connects to source of clamped signal or supply rail |
| 2 | Anode of Diode 2 (A2) | Independent input node for second Schottky path; enables dual-rail or redundant clamping |
| 3 | Common Cathode (K1/K2) | Shared output node; routes both diode currents to ground or reference potential |
Key Features
| Feature | Design Value |
|---|---|
| High switching speed | Enabled by low stored charge and Schottky barrier - supports >100 MHz pulse clamping |
| Low leakage current | 100 nA at 50 V ensures <1 µW standby dissipation in always-on monitoring circuits |
| High breakdown voltage | 70 V VR rating allows direct use in 48 V telecom and industrial control bus interfaces |
| Low capacitance | 2 pF junction capacitance avoids signal distortion in USB 2.0 or CAN FD data line protection |
Applications
| Power Supply Feedback Clamping | Digital Logic Level Translation |
|---|---|
Use Scenario: Clamp error amplifier output in isolated DC-DC converters to prevent overvoltage during load transients. IC Role / Device Role / Timing Role: Dual-anode Schottky provides bidirectional clamping between reference and feedback nodes using shared cathode. Use Value: 410 mV VF ensures tight voltage window (±0.4 V) around reference without loading the op-amp output. |
Use Scenario: Translate 3.3 V logic signals to 5 V tolerant inputs in mixed-voltage microcontroller systems. IC Role / Device Role / Timing Role: A1 clamps high-side, A2 clamps low-side; common cathode tied to 5 V rail for active pull-up/pull-down. Use Value: 2 pF capacitance prevents signal edge degradation at 25 MHz clock rates. |
| RF Detector Output Protection | USB Data Line ESD Clamping |
Use Scenario: Protect logarithmic amplifier input in RF power measurement circuits from antenna-induced transients. IC Role / Device Role / Timing Role: Dual diodes steer positive/negative surges to common cathode tied to VDD or ground via series resistor. Use Value: 100 nA IR prevents DC offset drift in µA-range detector bias networks. |
Use Scenario: Clamp D+ and D− lines in USB 2.0 host ports against ±8 kV contact ESD per IEC 61000-4-2. IC Role / Device Role / Timing Role: A1 and A2 connect to D+ and D−; common cathode routed to VBUS through current-limiting resistor. Use Value: 70 mA IF rating handles ESD pulse energy without thermal runaway under standard test conditions. |
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 package, 30 V VR, 200 mA IF | Lacks dual-anode topology; unsuitable for common-cathode clamping configurations | Select only when single-diode function suffices and board space permits larger footprint |
| Diodes Incorporated BAV99,215 | Two separate diodes in SOT23, no shared cathode; 70 V VR, 215 mA IF | Requires external cathode tie; higher VF (1.25 V typ.) reduces clamping precision | Prefer for discrete dual-path designs where independent cathode routing is needed |
Compared with BAS70-05, NSR0230HT1G offers higher current but lacks dual functionality, while BAV99,215 provides greater current headroom but sacrifices the integrated common-cathode advantage critical for compact feedback clamping.

FAQ
What is the maximum pulsed forward current rating for BAS70-05?
The non-repetitive peak forward current (IFSM) is rated at 100 mA for pulses ≤10 ms with initial junction temperature at 25 °C. This rating supports short-duration surge events such as ESD or inrush transients, provided average power dissipation remains within thermal limits defined by Rth(j-a) = 500 K/W.
Can BAS70-05 be used in automotive applications?
No - the BAS70-05 is explicitly designated as non-automotive qualified per Nexperia's revision history. It lacks AEC-Q101 qualification, temperature cycling validation, and automotive-specific reliability testing. For automotive use, Nexperia recommends the BAS70-05-Q variant or other AEC-Q101-certified dual Schottky alternatives.
How does the common cathode configuration affect PCB layout?
The shared cathode (Pin 3) simplifies routing by eliminating one net; both anodes (Pins 1 and 2) can be independently connected to different signal sources while referencing the same return path. This reduces trace count and parasitic inductance in high-speed clamp layouts, especially beneficial in feedback loops where ground bounce must be minimized.
Is BAS70-05 compatible with lead-free reflow soldering processes?
Yes - the SOT23 package is qualified for standard lead-free reflow profiles per JEDEC J-STD-020. The device withstands peak temperatures up to 260 °C for ≤40 seconds, and the recommended footprint matches Nexperia's sot023_fr land pattern with 0.5 mm solder mask defined pads and 0.6 mm paste apertures for optimal wetting and void control.
