Product details
Overview
BAV170T-7 from Diodes Incorporated is a surface-mount ultra-low-leakage dual diode in SOT-523 package, rated for 85 V peak reverse voltage and 125 mA forward current per diode, with typical reverse leakage of 5 nA at 75 V and 25°C - used in precision signal clamping and ESD protection circuits in automotive sensor interfaces.
For engineers reviewing the BAV170T-7 datasheet, BAV170T-7 pinout, BAV170T-7 application, or BAV170T-7 equivalent, key selection criteria include reverse leakage at high temperature, reverse recovery time under 3.0 μs, low capacitance (2 pF), AEC-Q101 qualification, and SOT-523 footprint compatibility in space-constrained PCB layouts.
Technical Context
This dual diode integrates two independent, isolated silicon junctions in a single ultra-small SOT-523 package. It operates across –65°C to +150°C with thermal resistance of 833°C/W and supports repetitive surge currents up to 500 mA.
The device exhibits tightly specified reverse breakdown ≥85 V at 100 μA, forward voltage ≤0.90 V at 1 mA, and reverse recovery time ≤3.0 μs under standardized 10 mA switching conditions - enabling reliable use in high-speed signal routing and transient suppression.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 85 V - maximum repetitive reverse voltage before breakdown; ensures robust blocking in 24 V/48 V automotive supply rails |
| IF (per diode) | 125 mA continuous - supports low-power signal path conditioning without thermal derating on standard FR-4 |
| IR @ 75 V | 5.0 nA @ 25°C - enables precision bias networks and high-impedance analog front-ends |
| trr | 3.0 μs - suitable for <1 MHz signal clamping and moderate-speed digital line protection |
| CT | 2 pF @ 0 V - minimizes capacitive loading on RF or high-frequency sensor signals |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling and HTRB |
| RθJA | 833 °C/W - requires minimal copper area for thermal management in compact layouts |
Pinout & Package
Package: SOT-523 - ultra-compact 3-terminal surface-mount plastic case (1.60 mm × 0.80 mm × 0.50 mm), lead-free matte tin plating, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (Pin 1) | First diode anode | Connected to input signal node for clamping or steering; shares common cathode with Anode 2 |
| Cathode (Pin 2) | Common cathode | Shared return path for both diodes; must be routed to reference rail with low inductance |
| Anode 2 (Pin 3) | Second diode anode | Enables dual-channel protection or bidirectional clamping in single-package layout |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low leakage | 5 nA @ 75 V, 25°C - preserves accuracy in high-Z feedback paths and battery-monitoring dividers |
| AEC-Q101 qualification | Validated for automotive underhood environments - supports deployment in engine control and ADAS sensor modules |
| SOT-523 footprint | 1.6 mm × 0.8 mm body - saves >60% board area vs. SOT-23 while maintaining solder joint reliability |
| Green molding compound | Halogen-free, UL 94V-0 rated - meets IPC-1752a environmental compliance for Tier 1 automotive supply chains |
Applications
| Automotive Sensor Signal Clamping | Low-Power ESD Protection |
|---|---|
Use Scenario: Protecting LIN bus transceiver inputs from load-dump transients and ESD events in cabin temperature sensors. IC Role / Device Role / Timing Role: Dual-diode clamp to VCC and GND, limiting signal swing to safe levels without loading the 12 kΩ LIN impedance. Use Value: 5 nA leakage prevents DC offset errors in ratiometric sensor outputs; 3.0 μs trr avoids distortion on 20.5 kbps LIN frames. | Use Scenario: I/O line protection for battery-powered IoT nodes with coin-cell supply and unshielded PCB traces. IC Role / Device Role / Timing Role: Low-capacitance (2 pF) bidirectional ESD clamp on UART/ADC lines, shunting ±8 kV contact discharge per IEC 61000-4-2. Use Value: Sub-1 V forward drop at 1 mA ensures clamping threshold remains below logic VIH/VIL margins; SOT-523 fits within 1.5 mm trace clearance zones. |
| Precision Reference Voltage Buffering | High-Impedance Analog Switch Interface |
Use Scenario: Isolating DAC output from multiplexer backfeed in medical-grade patient monitor front-ends. IC Role / Device Role / Timing Role: Back-to-back diode pair preventing reverse current flow into precision voltage references during channel switching. Use Value: 80 nA IR max at 150°C maintains reference stability over full industrial temperature range; 0.90 V VF at 1 mA minimizes voltage error. | Use Scenario: Steering logic-level signals between multiple ADC channels sharing a common reference buffer. IC Role / Device Role / Timing Role: Signal diode isolator ensuring no cross-talk between high-Z analog inputs during multiplexed sampling. Use Value: 2 pF capacitance avoids settling-time degradation on 16-bit SAR ADC inputs; SOT-523 allows placement directly at switch IC pins. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-leakage diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV199T-7-F | Same SOT-523 package; higher IF = 215 mA (single diode), but IR = 100 nA @ 75 V - 20× higher leakage than BAV170T-7 | Better for higher-current clamping; unsuitable where sub-10 nA leakage is required | Select when forward current >150 mA is needed and leakage tolerance >50 nA exists |
| BAS116T-7-F | Single diode, same package; VRRM = 85 V, IR = 5 nA @ 75 V, but no dual configuration | Requires two devices for dual-path protection; increases BOM count and layout area | Choose only if discrete single-diode implementation simplifies routing or thermal isolation is critical |
Compared with BAV199T-7-F, BAV170T-7 offers superior leakage performance for precision analog paths; compared with BAS116T-7-F, it delivers dual functionality in half the footprint - making it optimal for space- and leakage-sensitive dual-rail clamping.

FAQ
What is the polarity configuration of the BAV170T-7?
The BAV170T-7 is a dual-anode, common-cathode diode array. Pin 1 is Anode 1, Pin 2 is the shared Cathode, and Pin 3 is Anode 2. This configuration enables bidirectional clamping or independent signal steering with a single ground-return path, verified by Diodes Inc.'s official package diagram in DS30258 Rev. 12–2.
Is the BAV170T-7 suitable for 125°C ambient operation?
Yes - the device is rated for TJ and TSTG from –65°C to +150°C. At 125°C ambient, its leakage rises to 80 nA (max) at 75 V, and power dissipation must remain ≤50 mW per the derating curve in Figure 1, achievable with minimal copper pour on FR-4.
Does the BAV170T-7 have SPICE model support?
Yes - Diodes Incorporated provides a validated SPICE model for the BAV170T-7, accessible via their online SPICE models database referenced in DS30258 Rev. 12–2, page 1, under "Please click here to visit our online spice models database."
How does the SOT-523 package affect solder reflow yield?
The SOT-523's small size (1.6 mm × 0.8 mm) requires precise stencil aperture design and nitrogen-reflow profiling. Diodes Inc. specifies J-STD-020D Level 1 moisture sensitivity and MIL-STD-202-compliant solderability - confirmed with 99.8% first-pass yield using 0.15 mm laser-cut stencils and peak reflow at 245°C.
