Product details
Overview
BAV70HDW-7 from Diodes Incorporated is a dual high-speed switching diode array in SOT363 package, featuring 100 V peak reverse voltage, 4.0 ns reverse recovery time, and 1.5 pF capacitance at 0 V. It integrates two independent BAV70 circuits for signal routing or protection in compact analog interfaces and digital I/O conditioning.
For engineers reviewing the BAV70HDW-7 datasheet, BAV70HDW-7 pinout, BAV70HDW-7 application, or BAV70HDW-7 equivalent, key selection criteria include low-leakage performance (≤0.5 µA @ 80 V), fast switching capability, dual-diode integration in a 6-pin surface-mount package, and automotive-grade qualification path via BAV70HDWQ.
Technical Context
This dual diode array implements two independent, isolated silicon PN junctions optimized for high-frequency signal switching and clamping. Each element supports 250 mA forward current and exhibits matched electrical characteristics across temperature (−55°C to +150°C).
The device uses a common-cathode configuration per pair (pins 1–2–3 and pins 4–5–6), with low thermal resistance (357 °C/W) enabling stable operation under pulsed loads up to 450 mA peak forward surge current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage per diode, suitable for 24 V/48 V industrial bus clamping |
| tRR | 4.0 ns - Reverse recovery time at IF = IR = 10 mA, enabling >100 MHz signal switching |
| CT | 1.5 pF @ 0 V - Low junction capacitance minimizes signal distortion in RF and data line applications |
| IF | 250 mA continuous - Per-element forward current rating supports moderate-power level-shifting circuits |
| IR | ≤0.5 µA @ 80 V - Low leakage ensures minimal standby power loss in battery-backed systems |
| PD | 350 mW - Total package power dissipation on standard FR-4 board, defining thermal derating envelope |
Pinout & Package
SOT363 is a 6-pin, surface-mount plastic package measuring 2.15 mm × 2.10 mm × 0.95 mm, with matte tin-plated alloy 42 leadframe and UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode 1 | Input terminal for first diode element; connects to signal source in clamp or steering configuration |
| 2 | Cathode 1 | Common cathode node for first diode; ties to reference rail or logic threshold in level-shifting |
| 3 | Anode 2 | Input terminal for second independent diode; enables dual-path signal conditioning |
| 4 | Cathode 2 | Common cathode node for second diode; electrically isolated from Pin 2 for split-rail use |
| 5 | Anode 1 (redundant) | Not connected - internal bond wire stub; no functional connection per datasheet schematic |
| 6 | Anode 2 (redundant) | Not connected - internal bond wire stub; no functional connection per datasheet schematic |
Key Features

Applications
| USB Data Line Protection | LVDS Receiver Input Clamp |
|---|---|
Use Scenario: Protecting USB 2.0 D+/D− lines against ESD and overvoltage transients during hot-plug events. IC Role / Device Role / Timing Role: Bidirectional clamping diode array limiting voltage excursions to ±0.7 V above/below rails. Use Value: 1.5 pF capacitance avoids signal integrity degradation at 480 Mbps; 4.0 ns recovery prevents latch-up during fast transients. | Use Scenario: Preventing input stage damage in LVDS receivers exposed to ground bounce or crosstalk-induced overshoot. IC Role / Device Role / Timing Role: Low-capacitance shunt clamp placed between differential inputs and supply rails. Use Value: ≤0.5 µA leakage preserves receiver common-mode range; matched dual elements ensure symmetrical clamping behavior. |
| Microcontroller GPIO Protection | Industrial Sensor Signal Conditioning |
Use Scenario: Safeguarding 3.3 V/5 V microcontroller I/O pins against inductive kickback and external ESD. IC Role / Device Role / Timing Role: Discrete-level protection diode array routed between I/O pin and VCC/GND rails. Use Value: Dual configuration allows simultaneous protection of two GPIOs with shared cathode routing, reducing trace count. | Use Scenario: Conditioning analog output signals from pressure or temperature sensors before ADC sampling. IC Role / Device Role / Timing Role: Signal steering diode pair isolating sensor output from multiplexer backfeed or supply rail noise. Use Value: 100 V VRRM accommodates transient surges in 24 V industrial environments without breakdown. |
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 |
|---|---|---|---|
| BAV99DW-7 | Same SOT363 package, identical pinout, but 70 V VRRM and 3.0 ns tRR | Lower voltage rating limits use in 48 V systems; faster recovery suits higher-frequency RF detection | Select when 70 V blocking suffices and sub-4 ns recovery is critical |
| MMBD7000LT1G | SC-70-6 package, 100 V VRRM, 4.0 ns tRR, but higher IR (1 µA @ 80 V) | Smaller footprint (2.2 mm × 1.35 mm), but less thermal margin due to lower PD (200 mW) | Select for space-constrained designs where leakage <0.5 µA is not required |
Compared with BAV99DW-7 and MMBD7000LT1G, BAV70HDW-7 uniquely balances 100 V blocking, 4.0 ns speed, ultra-low leakage, and automotive qualification readiness-making it optimal for industrial I/O and robust USB interface protection.

FAQ
What is the maximum operating temperature for BAV70HDW-7?
The BAV70HDW-7 is rated for junction and storage temperatures from −55°C to +150°C. Its thermal resistance (RθJA = 357 °C/W) requires derating above +70°C ambient per Figure 1; at +125°C ambient, maximum continuous power drops to ~100 mW.
Is BAV70HDW-7 pin-compatible with BAV99DW-7?
Yes-BAV70HDW-7 and BAV99DW-7 share identical SOT363 pinout, internal dual-diode topology, and mechanical dimensions. They differ only in VRRM (100 V vs. 70 V) and tRR (4.0 ns vs. 3.0 ns), allowing direct substitution where voltage margin permits.
Does BAV70HDW-7 meet automotive qualification standards?
BAV70HDW-7 itself is not AEC-Q101 qualified, but its automotive-grade counterpart BAV70HDWQ is fully qualified to AEC-Q101, manufactured in IATF 16949 facilities, and supports PPAP documentation-enabling drop-in replacement in automotive designs.
How does the dual-diode configuration affect layout routing?
The BAV70HDW-7 contains two independent diodes with separate anodes (Pins 1 & 3) and separate cathodes (Pins 2 & 4); Pins 5 and 6 are NC. This allows flexible routing: each diode can be used in distinct signal paths, or cathodes can be tied together for common-rail clamping without cross-talk.
