Product details
Overview
BAV70T-7 from Diodes Incorporated is a dual high-speed switching diode in SOT523 package, rated for 85 V peak reverse voltage, 155 mA forward current per diode, and 4.0 ns reverse recovery time. It delivers low forward voltage (0.855 V at 10 mA) and low junction capacitance (0.81 pF at 0 V), enabling use in high-frequency signal routing and clamping in compact consumer and industrial power management circuits.
For engineers reviewing the BAV70T-7 datasheet, BAV70T-7 pinout, BAV70T-7 application, or BAV70T-7 equivalent, key selection criteria include reverse recovery speed, dual-diode configuration in ultra-small SOT523, thermal resistance (833 °C/W), leakage current at elevated temperature, and compatibility with automated SMT assembly on FR-4 PCBs.
Technical Context
The BAV70T-7 integrates two independent silicon epitaxial planar diodes in a single SOT523 package with common cathode configuration confirmed by Diodes' marking diagram and internal schematic. Its fast switching behavior stems from low carrier lifetime design, enabling sub-4 ns trr under 10 mA IF/IR conditions with 0.1×IR tail current.
Thermal performance is defined for FR-4 mounting with recommended pad layout: maximum junction temperature is +150°C, and derating begins at +25°C ambient, reaching zero current capability at +150°C for double-diode operation. The device operates reliably from –55°C to +150°C with moisture sensitivity level 1 per J-STD-020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 85 V - supports DC blocking and transient suppression up to 85 V peak reverse stress without breakdown |
| trr | 4.0 ns - enables reliable operation in >100 MHz signal switching and RF detector applications |
| VF @ 10 mA | 0.855 V - minimizes conduction loss in low-voltage logic-level clamping and level-shifting circuits |
| CT @ 0 V | 0.81 pF - reduces capacitive loading in high-speed data line protection and antenna switching paths |
| IR @ 75 V | 2.0 µA - ensures low standby leakage in battery-powered sensor interface and always-on monitoring nodes |
| RθJA | 833 °C/W - defines thermal limit for continuous 75 mA double-diode operation on standard FR-4 with minimal copper area |
| TJ Range | –55°C to +150°C - qualified for extended-temperature industrial control and automotive under-hood auxiliary circuits |

Applications
| USB Data Line Protection | RF Signal Routing Switch |
|---|---|
Use Scenario: Protecting USB 2.0 D+/D− lines from ESD transients and overvoltage during hot-plug events. IC Role / Device Role / Timing Role: Dual-anode clamping diode with common cathode to ground, providing bidirectional low-capacitance surge shunting. Use Value: 0.81 pF capacitance avoids signal integrity degradation at 480 Mbps; 4.0 ns trr prevents latch-up during fast ESD pulses. | Use Scenario: Selecting between two antenna inputs in a dual-band IoT transceiver module. IC Role / Device Role / Timing Role: High-speed RF switch using forward-biased diodes as low-resistance paths and reverse-biased state as isolation element. Use Value: 0.855 V VF ensures minimal insertion loss at 2.4 GHz; 85 V VRRM supports bias voltage headroom for PA output coupling. |
| Low-Voltage Logic Level Shifter | Power Supply OR-ing Circuit |
Use Scenario: Translating 1.8 V GPIO signals to 3.3 V domain in microcontroller-based sensor hubs. IC Role / Device Role / Timing Role: Passive level translator using forward voltage drop across one diode leg to offset logic thresholds. Use Value: Tight VF distribution (0.715–1.25 V) ensures predictable threshold shift; dual configuration allows simultaneous up/down translation. | Use Scenario: Combining outputs from redundant 5 V DC-DC converters in industrial PLC power supplies. IC Role / Device Role / Timing Role: Low-loss OR-ing diode pair preventing backfeed while supporting load current sharing. Use Value: 155 mA per diode rating handles typical 100 mA rail loads; 0.855 V VF limits power dissipation to <86 mW per diode at full load. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99T-7-F | Identical SOT523 package, same 85 V VRRM and 4.0 ns trr, but optimized for higher-reliability automotive-grade screening (AEC-Q101 qualified). | Required for automotive infotainment power sequencing where PPAP documentation and IATF16949 traceability are mandatory. | Select BAV99T-7-F when AEC-Q101 qualification and change-controlled manufacturing are contractually required. |
| MMBD7000LT1G | Same dual-common-cathode topology in SOT-23 package; slightly higher VF (0.88 V @ 10 mA) and larger footprint (3.0 mm × 1.4 mm vs. 1.6 mm × 1.6 mm). | Suitable for legacy designs with SOT-23 land patterns; not viable for space-constrained wearables or miniaturized modules. | Choose MMBD7000LT1G only if board real estate permits larger package and existing SOT-23 tooling eliminates requalification cost. |
Compared with BAV99T-7-F, the BAV70T-7 offers identical electrical performance at lower qualification cost, while MMBD7000LT1G trades size for broader distributor availability and longer production history-making BAV70T-7 optimal for cost-sensitive, space-constrained industrial and consumer designs.

FAQ
What is the polarity configuration of the BAV70T-7?
The BAV70T-7 uses a common-cathode dual-diode configuration: Pin 1 is Anode 1, Pin 2 is the shared Cathode, and Pin 3 is Anode 2. This is confirmed by Diodes' official marking diagram in DS30260 Rev. 13–2, where "JJ" marking aligns with the SOT523 top-view orientation showing Pin 1 left, Pin 2 center, Pin 3 right.
Is the BAV70T-7 suitable for automotive applications?
The BAV70T-7 is not AEC-Q101 qualified and lacks PPAP documentation or IATF16949-certified manufacturing records. For automotive use, Diodes specifies the BAV99TQ-13-F variant, which undergoes additional screening, change control, and process validation per AEC-Q101 requirements.
What is the maximum continuous forward current per diode?
The maximum continuous forward current per diode is 155 mA at TA = +25°C, derating linearly to 0 mA at +150°C ambient per the current derating curve in DS30260 Rev. 13–2 Figure 4. This rating assumes mounting on FR-4 with Diodes' recommended pad layout and no forced airflow.
Does the BAV70T-7 have a built-in thermal pad or exposed metal slug?
No. The SOT523 package used for BAV70T-7 has no exposed thermal pad or metal slug; thermal dissipation occurs solely through the leads and molded plastic body. Its RθJA of 833 °C/W reflects this limitation and requires careful PCB copper area allocation for thermal management.
