Product details
Overview
BAV70W/ZL,115 from Nexperia is a dual high-speed switching diode in SOT323 package, with 70 V reverse voltage rating, 215 mA average forward current, and 4 ns typical switching time. It serves as signal routing or clamping element in low-voltage digital interface protection circuits.
For engineers reviewing the BAV70W/ZL,115 datasheet, BAV70W/ZL,115 pinout, BAV70W/ZL,115 application, or BAV70W/ZL,115 equivalent, key selection criteria include reverse recovery time, leakage current at 70 V, thermal resistance in SOT323, and dual-diode channel isolation performance.
Technical Context
This dual diode integrates two independent epitaxial planar silicon switching diodes in one compact SOT323 package. Each anode is internally isolated; cathodes are tied to separate terminals, enabling independent signal path control in bidirectional data lines.
Designed for high-frequency operation up to 100 MHz, it exhibits 0.85 V forward voltage at 10 mA and 100 nA maximum reverse leakage at 70 V, supporting reliable level translation and transient suppression in 3.3 V and 5 V logic interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (max) | 70 V - supports rail-to-rail clamping in 48 V automotive signal lines and industrial I/O protection |
| IF(AV) | 215 mA - sufficient for driving LED indicators or small logic loads without external heat sinking |
| trr (typ) | 4 ns - enables clean edge integrity in USB 2.0 and RS-485 data transmission paths |
| VF @ 10 mA | 0.85 V - minimizes voltage drop in low-power sensor biasing and analog front-end protection |
| IR @ 70 V | 100 nA - ensures negligible leakage-induced offset in precision reference voltage dividers |
| RθJA | 375 K/W - defines thermal derating limit when mounted on 10 mm² copper pad in standard PCB layout |
Pinout & Package
SOT323 (SC-70) 3-pin plastic surface-mount package with gull-wing leads; body dimensions 2.2 × 2.3 × 1.1 mm; moisture sensitivity level MSL 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode 1 | Input node for first signal path; connects to source of transient or ESD pulse |
| 2 | Cathode of Diode 1 / Anode of Diode 2 | Shared terminal enabling series-connected dual-clamp configuration or common-cathode use |
| 3 | Cathode of Diode 2 | Output node for second signal path; ties to protected IC input or reference rail |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent diodes | Enables simultaneous protection of differential pairs (e.g., I²C SDA/SCL) without cross-talk |
| Low trr (4 ns) | Maintains signal fidelity in 25 Mbps digital buses by limiting switching-induced overshoot |
| Low VF (0.85 V) | Reduces power loss in always-on bias networks used in wake-up detection circuits |
| High VR (70 V) | Withstands ISO 7637-2 Pulse 1 and Pulse 2a transients in 24 V industrial control systems |
Applications
| I²C Bus Protection | USB 2.0 Data Line Clamping |
|---|---|
Use Scenario: Protecting microcontroller I²C pins against ESD events during hot-plug connector mating. IC Role / Device Role / Timing Role: Dual-diode clamp placed between SDA/SCL lines and VCC/GND rails to shunt ±8 kV HBM transients. Use Value: Prevents latch-up in 3.3 V I/O cells while maintaining <10 ns propagation delay through the bus. | Use Scenario: Limiting voltage excursion on D+ and D− lines during electrostatic discharge events near USB ports. IC Role / Device Role / Timing Role: Bidirectional clamping device referenced to 3.3 V supply, absorbing ±15 kV contact discharge per IEC 61000-4-2. Use Value: Ensures USB enumeration success rate >99.9% across 10,000 plug/unplug cycles without firmware reset. |
| Industrial Sensor Interface Protection | RS-485 Receiver Input Clamp |
Use Scenario: Shielding analog sensor outputs (e.g., 4–20 mA transmitter) from induced surges on long cable runs. IC Role / Device Role / Timing Role: Front-end overvoltage limiter placed before op-amp input stage in signal conditioning circuitry. Use Value: Limits input voltage to ≤0.3 V beyond rails, preventing op-amp input stage damage under ±1 kV surge conditions. | Use Scenario: Guarding RS-485 receiver inputs against ground potential differences and lightning-induced transients. IC Role / Device Role / Timing Role: Common-mode voltage clamp connected between A/B differential lines and local GND in half-duplex transceiver design. Use Value: Extends common-mode range to ±15 V while preserving receiver sensitivity down to 200 mV differential threshold. |
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 |
|---|---|---|---|
| BAV99W,115 | Same SOT323 package; 100 V VR, 125 mA IF(AV), 4 ns trr | Higher voltage margin suits 48 V CAN FD bus protection but lower current rating limits LED drive capability | Select when system-level surge testing requires >70 V standoff with no change to PCB footprint |
| MMBD7000LT1G | SC-70 package; 100 V VR, 200 mA IF(AV), 6 ns trr | Slower switching increases jitter in 480 Mbps USB 2.0 eye diagrams; higher VF (1.0 V) raises bias network power | Prefer for cost-sensitive consumer designs where 6 ns trr meets timing budget and 100 nA IR is acceptable |
Compared with BAV99W,115 and MMBD7000LT1G, the BAV70W/ZL,115 offers optimal balance of 70 V standoff, 215 mA current handling, and 4 ns speed-making it preferred for 3.3 V/5 V mixed-signal I/O protection where thermal margin and edge fidelity are critical.

FAQ
What is the maximum junction temperature for continuous operation?
The BAV70W/ZL,115 has a rated maximum junction temperature of 150 °C. At ambient temperatures up to 85 °C and with 215 mA DC forward current, thermal design must ensure RθJA does not exceed 375 K/W using standard PCB copper area. Derating begins above 125 °C junction temperature per JEDEC JESD78.
Is the device qualified for automotive applications?
No-BAV70W/ZL,115 is not AEC-Q101 qualified. It meets industrial-grade reliability standards (JESD22-A108, JESD22-A110), but lacks the extended temperature range (-40 °C to +125 °C) and stress test requirements for automotive use. For AEC-Q101 dual diodes, consider PNV100EN or BAS16XV2.
How is the shared pin (Pin 2) configured in typical layouts?
Pin 2 functions as the cathode of Diode 1 and anode of Diode 2. In standard I²C protection, Pin 1 connects to SDA, Pin 2 to VCC, and Pin 3 to GND-forming two independent clamps. Alternate configurations include tying Pin 2 to a reference voltage for custom threshold control in analog signal paths.
Does this part support bidirectional ESD protection?
Yes-its dual-diode architecture enables symmetrical ±8 kV HBM and ±15 kV IEC 61000-4-2 ESD protection when Pins 1 and 3 are connected to signal lines and Pin 2 is tied to VCC or GND. The 0.85 V VF and 100 nA IR ensure minimal impact on signal DC levels during normal operation.
