Product details
Overview
BAV99W-QF from Nexperia is a high-speed switching double diode in SOT323 (SC-70) package, configured as a common-cathode/anode dual diode pair with reverse recovery time ≤ 4 ns, capacitance ≤ 1.5 pF, and 100 V reverse voltage rating - used for polarity protection and signal routing in automotive infotainment power rails.
For engineers reviewing the BAV99W-QF datasheet, BAV99W-QF pinout, BAV99W-QF application, or BAV99W-QF equivalent, this page delivers verified pin functions, AEC-Q101 qualification status, thermal resistance (Rth(j-a) = 625 K/W), forward voltage at 10 mA (855 mV), and real-world switching performance metrics under defined test conditions.
Technical Context
This dual diode integrates two independent PN junctions sharing a common terminal (Pin 3 = K1/A2), enabling bidirectional clamping or series/anti-parallel switching configurations. Its trr ≤ 4 ns is measured under IF = 10 mA / IR = 10 mA / RL = 100 Ω, with peak forward recovery voltage ≤ 1.75 V.
Thermal design relies on Rth(j-sp) = 300 K/W to solder point and Rth(j-a) = 625 K/W in free air on FR4 PCB; maximum junction temperature is 150 °C, and ambient operating range spans −65 °C to +150 °C - validated per AEC-Q101 stress testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 100 V - supports 24 V automotive systems with 4× safety margin against transients. |
| Reverse Recovery Time (trr) | ≤ 4 ns - enables >100 MHz switching in RF front-end protection and data line clamping. |
| Diode Capacitance (Cd) | ≤ 1.5 pF at 0 V - minimizes signal distortion in high-frequency USB/UART lines. |
| Forward Voltage (VF) | 855 mV at 10 mA - ensures low conduction loss in always-on bias networks. |
| Reverse Leakage (IR) | ≤ 0.5 µA at 80 V, 25 °C - maintains integrity in low-power sensor biasing paths. |
| Power Dissipation (Ptot) | 200 mW at Tamb ≤ 25 °C - defines thermal derating limit for continuous operation. |
Pinout & Package
Package: SOT323 (SC-70), 3-lead surface-mount plastic package, body dimensions 2.0 mm × 1.25 mm × 0.95 mm, 1.3 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 | Cathode of Diode 2 (K2) | Return node for second diode; used in anti-parallel configuration with Pin 1. |
| 3 | Common Terminal (K1/A2) | Shared cathode of Diode 1 and anode of Diode 2 - enables dual-direction clamping or OR-ing. |
Key Features
| Feature | Design Value |
|---|---|

Applications
| Automotive Infotainment Power Rails | USB 2.0 Data Line Protection |
|---|---|
Use Scenario: Reverse polarity protection on 12 V supply inputs to head unit MCUs and display drivers. IC Role / Device Role / Timing Role: Dual-diode clamp prevents damage during battery jump-start misconnection or alternator load dump. Use Value: Withstands 100 V reverse stress and operates reliably across −40 °C to +125 °C ambient - meets ISO 16750-2 pulse 4a requirements. |
Use Scenario: ESD and transient suppression on D+/D− lines of automotive USB ports. IC Role / Device Role / Timing Role: Low-capacitance dual diode shunts ±15 kV HBM transients to ground while preserving 480 Mbps signal integrity. Use Value: 1.5 pF capacitance avoids USB eye diagram closure; 4 ns trr prevents data corruption during fast transients. |
| Industrial Sensor Signal Conditioning | Low-Power IoT Node Bias Networks |
Use Scenario: Input protection and level translation in 4–20 mA loop receivers with microcontroller ADC inputs. IC Role / Device Role / Timing Role: Common-cathode/anode configuration isolates analog input from overvoltage events while maintaining DC accuracy. Use Value: 0.5 µA max leakage at 80 V ensures <0.1% error in µA-level current sensing circuits. |
Use Scenario: Power path OR-ing and backup supply selection in coin-cell–powered BLE modules. IC Role / Device Role / Timing Role: Dual diode enables seamless switchover between primary and backup sources with minimal forward drop. Use Value: 855 mV VF at 10 mA limits voltage loss in sub-100 µA standby mode - extends battery life by >12% vs. Schottky alternatives. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed dual diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99W,115 (Nexperia) | No AEC-Q101 qualification; identical electrical specs and pinout. | Not approved for automotive production; suitable for industrial prototypes only. | Select when AEC-Q101 is not required and cost sensitivity outweighs qualification assurance. |
| DMN3020LSD-13 (Diodes Inc.) | Single N-channel MOSFET (30 V, 4.5 A); different function - active load switch, not diode. | Replaces mechanical switches in power sequencing; cannot perform clamping or rectification. | Only consider if redesigning for active control instead of passive protection - not a drop-in replacement. |
Compared with BAV99W-QF, the BAV99W,115 offers identical performance without automotive qualification, while DMN3020LSD-13 serves a fundamentally different circuit role - making the former a true alternative and the latter a functional mismatch requiring schematic revision.

FAQ
What is the maximum allowable junction temperature for BAV99W-QF?
The absolute maximum junction temperature (Tj) is 150 °C, as specified in Table 5 (Limiting values). Operation above this threshold risks permanent degradation of the PN junctions. Derating begins at Tamb > 25 °C, with Ptot decreasing linearly to zero at 150 °C ambient when mounted on standard FR4 PCB.
Can BAV99W-QF be used in place of a single high-speed diode?
Yes - either diode can be used independently by connecting unused pins to appropriate potentials. For example, using only Diode 1 requires tying Pin 2 (K2) to ground or floating it (with guard ring), while Pin 3 (K1/A2) serves as cathode. Full functionality requires all three pins.
Is the marking code 'A7%' standardized across all BAV99W-QF production lots?
Yes - 'A7' is the fixed device identifier per Table 4; '%' is a placeholder for the manufacturing site code (e.g., 'A', 'B', or 'C'), which varies by fab location but does not affect electrical or mechanical specifications. All marked units meet identical AEC-Q101 requirements.
How does thermal resistance change when both diodes conduct simultaneously?
When both diodes operate concurrently, total power dissipation remains within the 200 mW limit, but localized heating increases. Rth(j-a) stays at 625 K/W, though effective junction temperature rises faster due to shared thermal mass - derating to 130 mA total forward current (per Table 5) ensures safe operation.
