Product details
Overview
BAV70DW-7-F from Diodes Incorporated is a dual-channel surface-mount switching diode array in SOT363 package, featuring 80 V peak repetitive reverse voltage, 300 mA forward current per element, and 4.0 ns reverse recovery time. It integrates two independent BAV70 diodes for compact signal routing in high-speed logic interface and ESD protection circuits.
For engineers reviewing the BAV70DW-7-F datasheet, BAV70DW-7-F pinout, BAV70DW-7-F application, or BAV70DW-7-F equivalent, key selection criteria include reverse recovery time, leakage current at elevated temperature, dual-element isolation, and thermal resistance to ambient (625 °C/W) under FR-4 PCB mounting conditions.
Technical Context
The BAV70DW-7-F implements two independent, isolated silicon planar epitaxial switching diodes in a single 6-pin SOT363 package. Each diode exhibits low forward voltage (≤0.855 V @ 10 mA), sub-5 ns reverse recovery time, and <50 µA reverse leakage at 75 V and +25°C.
Its design supports high-frequency signal clamping and logic-level translation where fast turn-off and minimal charge storage are critical. The device operates across –55°C to +150°C and maintains ≤2.5 µA IR at VR = 75 V and TA = +25°C, enabling reliable performance in automotive and industrial control environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRMS | 57 V - Enables safe AC-coupled signal handling in 48 V rail monitoring paths |
| tRR | 4.0 ns - Supports >100 MHz digital signal edge clamping without tail current distortion |
| IF | 300 mA continuous - Sustains logic-level current drive for multiple TTL/CMOS inputs |
| RθJA | 625 °C/W - Requires minimum 1-in² copper pour on FR-4 for full 200 mW power dissipation |
| CT | 1.5 pF @ 0 V - Minimizes capacitive loading on high-impedance analog sensor nodes |
| IR @ 75 V | ≤2.5 µA @ +25°C - Ensures low standby power loss in always-on battery-backed circuits |
Pinout & Package
Package: SOT363 - 6-pin, 2.2 mm × 2.1 mm × 1.0 mm surface-mount plastic package with matte tin-plated alloy 42 leadframe; moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A1) | Anode of Diode 1 | Input node for first switching path; connects to signal source requiring clamping or steering |
| 2 (C1) | Cathode of Diode 1 | Output node tied to reference or pull-up; forms unidirectional conduction path with A1 |
| 3 (A2) | Anode of Diode 2 | Independent input for second signal channel; electrically isolated from Diode 1 |
| 4 (GND) | Common Cathode Tie (Not Internally Connected) | No internal connection; used as mechanical ground pad or optional thermal relief anchor |
| 5 (C2) | Cathode of Diode 2 | Second output node; enables dual-rail clamping or bidirectional signal conditioning |
| 6 (A1/A2 Shared) | Not Applicable - Pin 6 is Anode 1 (A1) per top-view marking | Top-view marking "KJA" confirms Pin 1 = A1, Pin 2 = C1, Pin 3 = A2, Pin 5 = C2; Pin 4 and Pin 6 are unused terminals per internal schematic |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent diodes | Enables compact dual-signal routing without cross-talk; eliminates need for two discrete SOT23 devices |
| 4.0 ns reverse recovery | Reduces switching losses in >50 MHz clock line protection and data line transient suppression |
| ≤2.5 µA reverse leakage @ 75 V | Maintains signal integrity in high-impedance analog front-ends and battery-monitoring dividers |
| SOT363 footprint | Reduces PCB area by 40% vs. two SOT23-3 packages; compatible with standard 0.65 mm pitch pick-and-place |
Applications
| High-Speed Logic Interface | ESD Protection for USB Data Lines |
|---|---|
Use Scenario: Clamping fast-rising edges between mixed-voltage logic families (e.g., 3.3 V MCU I/O to 5 V peripheral). IC Role / Device Role / Timing Role: Bidirectional voltage limiter that conducts only when signal exceeds VCC + 0.7 V or falls below GND − 0.7 V. Use Value: Prevents latch-up with 4.0 ns tRR and 1.5 pF capacitance, preserving signal rise/fall times under 2 ns. | Use Scenario: Protecting D+ and D− lines of USB 2.0 ports against ±8 kV contact discharge per IEC 61000-4-2. IC Role / Device Role / Timing Role: Low-capacitance shunt clamp that activates before transceiver damage threshold is reached. Use Value: 1.5 pF CT minimizes signal degradation at 480 Mbps; dual elements protect both lines independently. |
| Automotive Sensor Signal Conditioning | Power Supply Rail Clamp |
Use Scenario: Isolating and conditioning analog outputs from Hall-effect or thermistor-based sensors in engine control units. IC Role / Device Role / Timing Role: Reverse-polarity and overvoltage protector placed ahead of ADC input stage. Use Value: Operates from –55°C to +150°C; ≤50 µA IR at +150°C ensures stable biasing in under-hood environments. | Use Scenario: Preventing back-EMF damage during hot-swap of 12 V auxiliary modules in infotainment systems. IC Role / Device Role / Timing Role: Fast-acting flyback path for inductive load turn-off energy. Use Value: 450 mA IFRM handles surge currents; 80 V VRRM covers nominal 12 V system transients up to ±60 V. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99DW-7-F | Higher VRRM = 100 V; identical tRR, package, and pinout | Better suited for 24 V industrial bus clamping where 80 V margin is insufficient | Select when reverse voltage stress exceeds 80 V but same speed and layout compatibility are required |
| MMBD7000-7-F | Single-diode SOT23; 100 V VRRM; 4 ns tRR; higher VF (0.85 V @ 10 mA) | Requires two placements for dual function; less space-efficient than BAV70DW-7-F | Choose only if board real estate allows separate placement and higher forward drop is acceptable |
Compared with BAV99DW-7-F and MMBD7000-7-F, the BAV70DW-7-F offers optimal balance of 80 V rating, dual integration, and 4.0 ns speed for cost-sensitive 12 V–48 V signal routing, while avoiding the layout overhead of discrete singles or over-spec'd 100 V variants.

FAQ
What is the maximum junction temperature for continuous operation?
The BAV70DW-7-F has an operating junction temperature range of –55°C to +150°C. Its thermal resistance RθJA is 625 °C/W on standard FR-4 PCB layout, meaning sustained 200 mW dissipation requires ambient temperature ≤125°C to avoid exceeding TJ = +150°C. Derating begins linearly above +25°C ambient per Figure 1.
Is the SOT363 package lead-free and RoHS compliant?
Yes. The BAV70DW-7-F uses matte tin finish over alloy 42 leadframe and green molding compound meeting RoHS 2015/863/EU, with <900 ppm bromine, <900 ppm chlorine, and <1000 ppm antimony. It is fully lead-free, halogen-free, and certified to UL 94V-0 flammability standard.
How are the two diodes internally connected in the SOT363 package?
The BAV70DW-7-F contains two completely independent diodes: Diode 1 (Anode = Pin 1, Cathode = Pin 2) and Diode 2 (Anode = Pin 3, Cathode = Pin 5). Pins 4 and 6 are not internally connected - Pin 4 serves as a thermal pad anchor, and Pin 6 is unused per top-view marking "KJA" and internal schematic.
Can this device replace a single BAV70 in existing designs?
No - the BAV70DW-7-F is a dual-diode array and cannot directly substitute a single-diode BAV70 (e.g., SOT23-3 BAV70-7-F) without PCB layout revision. However, it replaces two discrete BAV70s, reducing component count and board area. Pin mapping differs: BAV70DW-7-F uses six pins across two isolated anode/cathode pairs, not three pins.
