Product details
Overview
BAV70TA from Diodes Incorporated is a dual surface-mount switching diode in SOT23 package, featuring 75 V peak repetitive reverse voltage, 300 mA forward continuous current, 4.0 ns reverse-recovery time, and 2.0 pF total capacitance at 0 V - optimized for high-speed signal routing in compact consumer and industrial PCBs.
For engineers reviewing the BAV70TA datasheet, BAV70TA pinout, BAV70TA application, or BAV70TA equivalent, key selection criteria include fast switching performance (trr ≤ 4.0 ns), low junction-to-ambient thermal resistance (357 °C/W), dual-element integration in SOT23, and compatibility with automated SMT assembly lines requiring RoHS-compliant, halogen-free components.
Technical Context
The BAV70TA integrates two independent silicon switching diodes in a single SOT23-3 package with common cathode configuration (Pin 1: Anode 1, Pin 2: Cathode, Pin 3: Anode 2). It operates across –55 °C to +150 °C and supports repetitive surge currents up to 450 mA.
Its electrical behavior is defined by low forward voltage (0.715 V @ 1 mA), tight reverse leakage control (≤2.5 µA @ 75 V, 25 °C), and stable capacitance (2.0 pF @ 1 MHz, 0 V), enabling predictable timing and signal integrity in clamping, steering, and logic-level translation circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 75 V - Maximum working reverse voltage before breakdown; sets safe operating margin for 5 V–24 V rail protection |
| IFM | 300 mA - Continuous forward current per diode; supports moderate-signal switching without derating at 25 °C |
| trr | 4.0 ns - Reverse recovery time; enables reliable operation up to ~80 MHz digital signal frequencies |
| CT | 2.0 pF @ 0 V, 1 MHz - Junction capacitance per element; minimizes signal distortion in RF and high-speed data paths |
| RθJA | 357 °C/W - Thermal resistance on FR-4 board; requires minimal copper area for thermal management in space-constrained layouts |
| VF | 0.855 V @ 10 mA - Forward voltage drop; ensures low power loss and minimal voltage offset in level-shifting applications |
Pinout & Package
Package: SOT23 - 3-pin, surface-mount plastic package (2.90 mm × 1.30 mm × 1.03 mm), UL 94V-0 rated, moisture sensitivity level 1, matte tin-plated alloy 42 leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Diode 1 | Input node for first switching path; connects to signal source or pull-up network |
| Pin 2 | Common Cathode | Shared return path for both diodes; ties to ground or reference potential |
| Pin 3 | Anode of Diode 2 | Independent input node for second switching path; enables dual-channel isolation |
Key Features
| Feature | Design Value |
|---|---|
| Fast switching speed | 4.0 ns trr enables use in >50 MHz clock/data line clamping and pulse shaping |
| Dual-diode integration | Two independent switching elements in one SOT23 footprint saves 30% board area vs. discrete singles |
| Low forward voltage | 0.715 V @ 1 mA reduces conduction loss in battery-powered sensor interface circuits |
| Green compliance | Halogen- and antimony-free (<900 ppm Br/Cl, <1000 ppm Sb); meets IEC 61249-2-21 and JEDEC J-STD-020 |
Applications
| USB Data Line Protection | Logic-Level Translation |
|---|---|
Use Scenario: Bidirectional ESD and overvoltage protection on USB 2.0 D+ and D− lines. IC Role / Device Role / Timing Role: Dual clamping diode array shunting transients to VCC and GND while preserving signal integrity. Use Value: 2.0 pF capacitance and 4.0 ns trr prevent data eye closure at 480 Mbps; common-cathode layout simplifies PCB routing. | Use Scenario: Voltage-level shifting between 3.3 V microcontroller GPIO and 5 V peripheral inputs. IC Role / Device Role / Timing Role: Passive diode-based level translator using forward conduction and pull-up resistors. Use Value: 0.715 V VF at 1 mA ensures accurate threshold alignment; dual configuration supports simultaneous TX/RX translation. |
| RF Signal Steering | Power Supply OR'ing |
Use Scenario: Antenna switching in sub-GHz ISM band transceivers (e.g., 868/915 MHz). IC Role / Device Role / Timing Role: Low-capacitance RF path selector isolating transmit/receive paths during TDD operation. Use Value: 2.0 pF CT minimizes insertion loss; 75 V VRRM accommodates PA output swing margins. | Use Scenario: Redundant 3.3 V supply selection in industrial controllers with dual DC inputs. IC Role / Device Role / Timing Role: Discrete OR-ing diode pair preventing backfeed between supplies during switchover. Use Value: 300 mA IFM rating supports typical 200–250 mA load current; SOT23 allows placement near connectors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99LT1G | Same SOT23-3, common-cathode topology; trr = 4 ns, VRRM = 70 V, VF = 1.25 V @ 150 mA | Slightly lower reverse voltage rating; higher VF increases conduction loss above 50 mA | Preferred where cost sensitivity outweighs 5 V VRRM margin and higher-current efficiency |
| MMBD7000LT1G | Common-anode configuration; VRRM = 70 V, trr = 4 ns, CT = 2.5 pF @ 0 V | Pinout reversal requires PCB redesign; 0.5 pF higher capacitance affects >200 MHz RF paths | Selected when common-anode architecture matches existing schematic topology or legacy layout |
Compared with BAV70TA, BAV99LT1G trades 5 V reverse margin for broader cost availability, while MMBD7000LT1G offers identical speed but demands layout adaptation due to inverted terminal mapping and slightly higher capacitance.

FAQ
Is BAV70TA pin-compatible with BAV99?
Yes - BAV70TA and BAV99 share identical SOT23-3 pinout (Anode1–Cathode–Anode2) and common-cathode configuration. Both meet JEDEC TO-236AB mechanical standards, allowing direct PCB footprint reuse without layout modification.
What is the maximum junction temperature during continuous operation?
The BAV70TA has an absolute maximum junction temperature of +150 °C. At 25 °C ambient and 300 mA forward current, junction temperature rise is approximately 107 °C (calculated via RθJA × PD), staying within limit only with adequate copper thermal relief or forced airflow.
Does BAV70TA support automotive qualification?
No - standard BAV70TA is not AEC-Q101 qualified. The automotive-grade variant is BAV70Q, which adds PPAP capability, change control, and IATF 16949-certified manufacturing. BAV70TA is rated for industrial temperature range (–55 °C to +150 °C) but lacks automotive-specific test documentation.
Can BAV70TA be used in 5 V logic clamping applications?
Yes - with 75 V VRRM and 0.855 V VF @ 10 mA, BAV70TA provides robust 5 V rail clamping. Its 2.0 pF capacitance avoids signal degradation on 5 V CMOS/TTL lines up to 100 MHz, and its 4.0 ns trr prevents latch-up during fast edge transitions.
