Product details
Overview
BAV70T,115 from Nexperia is a dual common-cathode high-speed switching diode in SOT416 (SC-75) package, rated for 100 V reverse voltage, 4 ns reverse recovery time, and 150 mA forward current at 90 °C junction temperature. It serves as a compact, AEC-Q101-qualified signal routing and clamping element in automotive infotainment power management and USB data line protection circuits.
For engineers reviewing the BAV70T,115 datasheet, BAV70T,115 pinout, BAV70T,115 application, or BAV70T,115 equivalent, this page delivers verified electrical parameters, thermal limits, SOT416 footprint details, and automotive-grade reliability context - all confirmed against Nexperia's official BAV70_SER Rev. 8 product data sheet.
Technical Context
The BAV70T,115 integrates two independent silicon epitaxial planar diodes sharing a single cathode terminal, enabling compact dual-path switching or polarity-selective clamping. Its ultra-small SOT416 package (1.3 × 0.8 × 0.4 mm) supports high-density PCB layouts while maintaining 1.5 pF capacitance at 0 V bias and 0.5 µA max reverse leakage at 80 V.
Designed for fast transient response, it achieves ≤4 ns reverse recovery time under 10 mA switching conditions with 100 Ω load, and operates reliably from −65 °C to +150 °C ambient, with junction temperature limited to 150 °C. Its AEC-Q101 qualification confirms suitability for automotive under-hood and dashboard electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 100 V - supports clamping in 24 V automotive systems with ≥2× safety margin against load-dump transients. |
| Reverse Recovery Time (trr) | ≤4 ns - enables reliable operation in >100 MHz digital signal routing and RF detector applications. |
| Diode Capacitance (Cd) | ≤1.5 pF at 0 V - minimizes signal distortion in high-frequency analog switches and ESD protection paths. |
| Forward Current (IF) | 150 mA at Ts = 90 °C - sustains continuous conduction in low-power logic-level translation and LED biasing. |
| Reverse Leakage (IR) | ≤0.5 µA at VR = 80 V - ensures low standby power loss in always-on automotive subsystems. |
| Junction Temperature (Tj) | 150 °C maximum - allows deployment in engine control unit (ECU) proximity without derating in sealed enclosures. |
Pinout & Package
SOT416 (SC-75) plastic surface-mounted package; 3-lead, ultra-small outline measuring 1.3 mm × 0.8 mm × 0.4 mm, optimized for reflow soldering on FR4 PCBs with standard 0.6 mm pad width and 0.7 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (Diode 1) | Input node for first diode path; connects to signal source or supply rail requiring unidirectional conduction. |
| 2 | Anode (Diode 2) | Independent input node for second diode path; enables dual-rail clamping or redundant signal steering. |
| 3 | Common Cathode | Shared output/return node; simplifies PCB routing by consolidating cathode connections into one trace or plane. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use per stress test requirements including temperature cycling, HTRB, and ESD-HBM ≥2 kV - eliminates need for additional qualification testing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV70W,115 | SOT323 (SC-70) package; larger 2.2 × 1.35 mm footprint; 175 mA IF at 25 °C ambient vs. 150 mA at 90 °C for BAV70T,115. | Better thermal dissipation in non-automotive consumer PCBs; less suitable for ultra-dense automotive modules. | Select BAV70W,115 when board space permits and higher ambient operating temperature margin is not required. |
| MMBD7000LT1G | Single-diode SOT23 package; 100 V VR, 4 ns trr, but no common-cathode dual configuration - requires two devices for equivalent functionality. | Increases component count and layout complexity; lacks matched thermal tracking between diodes. | Choose MMBD7000LT1G only if dual-diode integration is unnecessary and legacy SOT23 footprint compatibility is mandatory. |
Compared with BAV70T,115, BAV70W,115 offers higher ambient-current capability in a larger package, while MMBD7000LT1G provides identical per-diode specs but forces duplication to replicate dual-channel operation - making BAV70T,115 the optimal choice for space-constrained, thermally demanding automotive signal routing.

FAQ
What is the maximum reverse voltage rating for BAV70T,115?
The BAV70T,115 has a repetitive peak reverse voltage (VRRM) and DC reverse voltage (VR) rating of 100 V, as specified in Table 6 of the Nexperia BAV70_SER Rev. 8 datasheet. This rating applies per diode under continuous operation and supports design margin for automotive 24 V systems exposed to load-dump transients up to ISO 7637-2 Level III.
Does BAV70T,115 support reflow soldering only, or can it be wave-soldered?
Reflow soldering is the only recommended method for BAV70T,115, per Section 11 of the datasheet. Wave soldering is not supported due to thermal limitations of the SOT416 package and risk of damage to internal die attach. The device's thermal resistance from junction to solder point (Rth(j-sp)) is 350 K/W, optimized for controlled reflow profiles with peak temperatures ≤260 °C.
Is BAV70T,115 pin-compatible with other BAV70-series variants like BAV70W,115?
No - BAV70T,115 uses SOT416 (SC-75) with 1.3 × 0.8 mm dimensions and 0.7 mm lead pitch, while BAV70W,115 uses SOT323 (SC-70) with 2.2 × 1.35 mm dimensions and 0.65 mm pitch. Pin numbering (1–2–3) and circuit roles (anode–anode–common cathode) are identical, but physical footprints are incompatible without PCB redesign.
What is the typical forward voltage of BAV70T,115 at 10 mA forward current?
The typical forward voltage (VF) of BAV70T,115 is 855 mV at IF = 10 mA and Tamb = 25 °C, per Table 8 of the datasheet. At elevated junction temperatures (e.g., 125 °C), VF decreases to approximately 750 mV due to semiconductor physics, which must be accounted for in precision voltage-reference or current-sensing applications.
How does the AEC-Q101 qualification of BAV70T,115 impact its use in non-automotive applications?
The AEC-Q101 qualification of BAV70T,115 validates its robustness against temperature cycling, high-temperature reverse bias, and ESD stress - providing enhanced reliability margins even in industrial or medical applications. However, the qualification itself does not alter electrical specifications; BAV70T,115 performs identically in all environments, with its 150 °C Tj limit and −65 °C to +150 °C storage range supporting broad deployment beyond automotive.
