Product details
Overview
BAV70S-QF from Nexperia is a high-speed switching double diode in SOT363-3 (TSSOP6) package, configured as two independent anode-cathode pairs sharing common cathodes (K1/K2 and K3/K4), with 100 V reverse voltage rating, ≤4 ns reverse recovery time, and ≤1.5 pF capacitance - deployed in automotive signal routing and ESD-protected I/O interface stages.
For engineers reviewing the BAV70S-QF datasheet, BAV70S-QF pinout, BAV70S-QF application, or BAV70S-QF equivalent, key selection criteria include verified AEC-Q101 qualification, dual-diode topology with isolated anodes and split common cathodes, low trr for >100 MHz switching, and thermal resistance of 255 K/W junction-to-solder point under FR4 mounting.
Technical Context
The BAV70S-QF integrates two independent high-speed switching diodes in one TSSOP6 package, each rated for 100 V VR and 250 mA IF (per diode), with reverse recovery time measured at 4 ns under standardized IF = 10 mA / IR = 10 mA / RL = 100 Ω conditions.
Its dual-common-cathode structure (pins 3 and 6) enables flexible bidirectional clamping or series/parallel diode configurations without external interconnects, while low 1.5 pF capacitance at 0 V VR supports RF-sensitive signal path isolation up to 1 GHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 100 V - supports 24 V and 48 V automotive bus protection with 2× safety margin |
| Reverse Recovery Time (trr) | 4 ns - enables clean switching in >100 MHz clock distribution and data line termination |
| Diode Capacitance (Cd) | 1.5 pF at 0 V VR - minimizes signal loading on high-speed digital I/O and RF antenna switches |
| Forward Voltage (VF) | 855 mV at 10 mA - ensures low conduction loss in active clamping and level-shifting circuits |
| Reverse Current (IR) | 0.5 µA at 80 V, 25 °C - guarantees stable leakage performance in battery-backed sensor interfaces |
| Junction-to-Solder Point Rth | 255 K/W - defines thermal rise under pulsed operation on standard FR4 PCB with tin-plated copper |
Pinout & Package
Package: SOT363-3 (TSSOP6), 6-lead surface-mount plastic package with 0.65 mm pitch, 2.2 mm × 1.35 mm body size, and exposed solder pad-compatible footprint per Fig. 8.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (Diode 1) | Input node for first diode's forward conduction path; isolated from other anodes |
| 2 | Anode (Diode 2) | Independent input node for second diode; enables dual-channel signal steering |
| 3 | Common Cathode (Diodes 3 & 4) | Shared return path for third and fourth diodes - not used in BAV70S-QF's dual-diode configuration |
| 4 | Anode (Diode 3) | Unused in this variant; device implements only Diodes 1 and 2 per datasheet functional description |
| 5 | Anode (Diode 4) | Unused; pin remains unconnected in standard BAV70S-QF operation |
| 6 | Common Cathode (Diodes 1 & 2) | Single shared cathode node for both active diodes - simplifies PCB layout for clamp networks |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under stress test conditions including HTGB, HTRB, and temperature cycling - enables direct use in ADAS camera modules and infotainment I/O |
| 4 ns trr | Enables sub-10 ns edge transition handling in USB 2.0 and CAN FD signal conditioning without overshoot |
| 1.5 pF Cd | Reduces capacitive loading on 50 Ω transmission lines, preserving signal integrity in LVDS and MIPI D-PHY receivers |
| Dual-anode / common-cathode topology | Allows single-package implementation of dual-rail clamping (e.g., VDD and VIO rails) with shared ground return |
Applications
| Automotive Camera Interface Protection | USB 2.0 Data Line Clamping |
|---|---|
|
Use Scenario: Protecting MIPI CSI-2 differential pairs in rear-view camera modules against ESD and load dump transients. IC Role / Device Role / Timing Role: Dual-diode clamping network placed at connector side, with common cathode tied to chassis ground. Use Value: 4 ns trr prevents pulse distortion during 480 Mbps data bursts; 100 V VR withstands ISO 7637-2 Pulse 5a surges. |
Use Scenario: Bidirectional ESD suppression on D+ and D− lines of automotive USB host ports. IC Role / Device Role / Timing Role: Two independent diodes (pins 1–6 and 2–6) provide separate clamping paths to VBUS and GND. Use Value: 1.5 pF capacitance avoids signal eye closure; AEC-Q101 qualification ensures reliability across -40 °C to 125 °C ambient. |
| Industrial Sensor Signal Conditioning | Low-Voltage Logic Level Translation |
|
Use Scenario: Isolating analog sensor outputs (e.g., thermistor bridges) from microcontroller ADC inputs in PLC analog modules. IC Role / Device Role / Timing Role: High-speed diode pair used in precision rectifier front-end with op-amp feedback. Use Value: Low 0.5 µA IR at 80 V ensures <10 nA error current in 10 MΩ gain networks; 855 mV VF enables accurate zero-crossing detection. |
Use Scenario: Translating 1.8 V logic signals to 3.3 V domains in industrial gateways with mixed-voltage SoCs. IC Role / Device Role / Timing Role: Anode-driven level shifter using forward-biased diode drop between supply rails. Use Value: Consistent 855 mV VF at 10 mA allows predictable 1.45 V offset; dual-diode layout reduces board space vs. discrete solutions. |
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 |
|---|---|---|---|
| BAV99W-Q | Same SOT323-3 package; 100 V VR, 3 ns trr, but single common cathode for both diodes (no split cathode option) | Lacks independent cathode routing - unsuitable for dual-rail clamping where cathodes must be isolated | Select when compact footprint is critical and shared cathode suffices for system grounding scheme |
| NSR0230P2T5G | SOD-523 package; 30 V VR, 1.2 ns trr, 0.5 pF Cd - optimized for ultra-high-speed, low-voltage apps | Not AEC-Q101 qualified; VR too low for 24 V automotive systems requiring 100 V surge margin | Prefer for portable electronics with <5 V rails and >500 MHz signal bandwidth requirements |
Compared with BAV99W-Q and NSR0230P2T5G, the BAV70S-QF uniquely combines AEC-Q101 compliance, 100 V robustness, and dual-common-cathode flexibility - making it the only choice for dual-rail transient protection in automotive domain controllers where layout isolation and qualification are mandatory.

FAQ
What is the maximum continuous forward current rating per diode in the BAV70S-QF?
The BAV70S-QF is rated for 250 mA continuous forward current per diode at Ts = 60 °C, as specified in Table 5 (Limiting values). This rating assumes thermal management via solder-point conduction on FR4 PCB with standard footprint - exceeding this current risks junction overheating beyond the 150 °C absolute maximum.
Does the BAV70S-QF support bidirectional ESD clamping on separate voltage rails?
Yes - pins 1 and 2 serve as independent anodes, while pin 6 provides a shared cathode. This allows simultaneous clamping of two distinct signal lines (e.g., CAN_H and CAN_L) to the same reference, provided both lines share the same return path. Pin 3 is a separate common cathode unused in this configuration.
How does the 255 K/W thermal resistance impact PCB layout decisions?
The 255 K/W junction-to-solder-point thermal resistance requires direct thermal coupling to copper pour or internal ground planes. Layout must minimize solder joint thermal resistance by using full-pad reflow profiles and avoiding thermal relief on pin 6 (common cathode), as it serves as the primary heat exit path under pulsed conduction.
Is the BAV70S-QF pin-compatible with earlier BAV70S variants?
No - the BAV70S-QF uses SOT363-3 (TSSOP6), whereas legacy BAV70S parts used SOT363 (non–dash-3 variant) with different pin 1 indexing and mechanical tolerances. The datasheet revision history explicitly notes "Package changed from SOT363 to SOT363-3", confirming non-interchangeability without layout revision.
