Product details

Overview

BAV70T-7-F 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 serves as a compact signal routing or clamping element in low-power digital interface protection and level-shifting circuits.

For engineers reviewing the BAV70T-7-F datasheet, BAV70T-7-F pinout, BAV70T-7-F application, or BAV70T-7-F equivalent, key selection criteria include reverse recovery speed, leakage at elevated temperature, junction-to-ambient thermal resistance, and compatibility with FR-4 PCB layouts using Diodes' recommended SOT523 pad dimensions.

Technical Context

This dual-diode configuration shares a common cathode connection, enabling bidirectional clamping or series-switching topologies in space-constrained designs. Its 0.81 pF total capacitance at 0 V and 1 MHz supports high-frequency signal integrity up to ~200 MHz.

The device operates across –55°C to +150°C and delivers stable leakage performance: ≤100 nA at VR = 25 V and TJ = +150°C, and ≤60 µA at VR = 75 V and TJ = +150°C - critical for thermally demanding industrial sensor interfaces.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	85 V - supports input protection against transient spikes up to IEC 61000-4-5 Level 3 (1 kV surge)
I_F (per diode)	155 mA - sufficient for logic-level signal switching and low-current bias networks
t_rr	4.0 ns - enables clean edge transitions in 10–50 MHz clock distribution and data lines
C_T	0.81 pF @ 0 V, 1 MHz - minimizes capacitive loading on high-speed GPIO and USB D+/D− traces
R_θJA	833 °C/W - requires minimal copper area for thermal management in ambient ≤+75°C applications
I_R @ 75 V, 25°C	2.0 µA - ensures low standby power loss in always-on monitoring circuits

Pinout & Package

Package: SOT523 - ultra-small surface-mount outline (1.60 × 1.60 × 0.90 mm), lead-free matte tin plating over Alloy 42, moisture sensitivity level 1.

Pin/Terminal	Circuit Role	Design Meaning
1	Anode of Diode 1	Input node for unidirectional clamping or forward conduction path in channel A
2	Cathode (common)	Shared return path for both diodes; connects to reference rail or ESD ground plane

Key Features

Feature	Design Value

Applications

USB 2.0 Data Line Protection

Industrial Sensor Signal Conditioning

Use Scenario: Clamping ESD transients on D+ and D− lines before USB PHY interface.

IC Role / Device Role / Timing Role: Dual-anode, common-cathode diode array providing bidirectional TVS-like clamping with sub-ns response.

Use Value: 0.81 pF capacitance avoids signal integrity degradation at 480 Mbps; 85 V V_RRM withstands ±15 kV contact discharge per IEC 61000-4-2.

Use Scenario: Level-shifting analog sensor outputs (e.g., 0–5 V) to microcontroller ADC inputs referenced to different supply domains.

IC Role / Device Role / Timing Role: Precision forward-voltage drop (0.715 V @ 1 mA) used as passive offset generator in ratiometric scaling networks.

Use Value: Tight VF tolerance and low tempco enable <±2 mV offset stability across –40°C to +85°C operating range.

Low-Power Logic-Level Translation

RF Front-End Bias Switching

Use Scenario: Translating 1.8 V GPIO signals to 3.3 V peripherals in battery-powered IoT nodes.

IC Role / Device Role / Timing Role: Series-connected diode providing ~0.7 V forward drop to shift logic thresholds while preserving edge speed.

Use Value: 4.0 ns t_rr prevents pulse narrowing in 10 MHz control signals; 155 mA rating supports drive into 10 kΩ loads.

Use Scenario: Switching DC bias to GaAs FET amplifiers in sub-GHz wireless transceivers.

IC Role / Device Role / Timing Role: High-isolation switch controlling V_DD enable path with minimal RF leakage during OFF state.

Use Value: 0.81 pF CT and <2.0 µA IR at 25°C ensure >35 dB isolation at 900 MHz; SOT523 footprint saves board space near antenna feedlines.

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 V_RRM, but 3.0 ns t_rr (vs. 4.0 ns); VF slightly higher at 10 mA (0.855 V vs. 0.83 V typical)	Better suited for >50 MHz clock gating; marginally higher conduction loss in DC bias paths	Select when reverse recovery speed is prioritized over forward voltage drop
MMBD7000LT1G	SOT-23 package (larger footprint), 100 V V_RRM, 4.0 ns t_rr, but 1.25 V VF @ 150 mA - significantly higher forward loss	Preferred where higher surge robustness is needed and board area permits larger package	Choose only if 100 V rating is mandatory and thermal budget allows higher VF-related dissipation

Compared with BAV99T-7-F and MMBD7000LT1G, the BAV70T-7-F offers optimal balance of speed, size, and forward conduction efficiency for space-limited 25–40 MHz signal paths - especially where simultaneous low capacitance and sub-1 V VF are required.

FAQ

What is the polarity configuration of the BAV70T-7-F?

The BAV70T-7-F is a dual-diode array with anode-cathode-anode pinout (pins 1–2–3). Pin 2 is the common cathode; pins 1 and 3 are independent anodes. This configuration supports bidirectional clamping or two independent switching paths sharing one return node, confirmed by Diodes' DS30260 Rev. 13 schematic diagram and top-marking "JJ" orientation.

Is the BAV70T-7-F qualified for automotive applications?

No - the BAV70T-7-F is not AEC-Q101 qualified. Only the BAV99TQ variant in this family carries AEC-Q101 qualification, PPAP capability, and IATF16949 manufacturing certification. The BAV70T-7-F is intended for industrial, computing, and consumer applications meeting commercial-grade reliability requirements.

Can the BAV70T-7-F replace a single BAS16T diode?

Yes, but only one diode section should be used - connect pin 2 (cathode) and either pin 1 or pin 3 (anode), leaving the unused anode floating. The electrical specs (V_RRM, I_F, t_rr) match BAS16T per element, and the SOT523 package is identical. However, layout must accommodate the three-pin footprint versus BAS16T's two-pin SOT523.

What is the maximum allowable soldering temperature for BAV70T-7-F?

The BAV70T-7-F has a moisture sensitivity level (MSL) of 1 per J-STD-020, meaning it may be exposed to unlimited floor life at ≤30°C/60% RH and supports standard reflow profiles. Peak soldering temperature must not exceed 260°C for ≤10 seconds, as specified in Diodes' package outline documentation and confirmed by JEDEC J-STD-020D.2 compliance.
