Product details
Overview
BAV70W-Q from Nexperia is a high-speed switching double diode in SOT323 (SC-70) package, featuring common-cathode configuration, 100 V reverse voltage rating, ≤4 ns reverse recovery time, and ≤1.5 pF capacitance - used for signal routing and clamping in automotive infotainment power management stages.
For engineers reviewing the BAV70W-Q datasheet, BAV70W-Q pinout, BAV70W-Q application, or BAV70W-Q equivalent, key selection criteria include reverse recovery speed, low-junction capacitance for RF-adjacent signal paths, AEC-Q101 qualification status, and common-cathode dual-diode topology for compact bidirectional protection.
Technical Context
This dual diode integrates two independent high-speed epitaxial planar junctions sharing a single cathode terminal, enabling synchronous clamping or steering in half-wave rectification and logic-level translation circuits. Its trr ≤4 ns and Cd ≤1.5 pF at 0 V are measured under standardized IEC 60747-2 test conditions with IF = 10 mA, IR = 10 mA, and RL = 100 Ω.
The device operates across −65 °C to +150 °C ambient range, with thermal resistance Rth(j-a) = 625 K/W on FR4 PCB, and supports pulsed forward currents up to 4 A (tp = 1 µs), making it suitable for transient suppression in 12 V automotive subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 100 V - supports operation in 48 V automotive supply rails with margin against load-dump transients. |
| Reverse Recovery Time (trr) | ≤4 ns - enables reliable switching above 100 MHz in RF detector and high-frequency clamp applications. |
| Junction Capacitance (Cd) | ≤1.5 pF at 0 V - minimizes signal loading in 50 Ω impedance-matched paths such as antenna switch control lines. |
| Forward Voltage (VF) | 855 mV at 10 mA - ensures low conduction loss in low-power logic-level interface circuits. |
| Reverse Leakage (IR) | ≤0.5 µA at 80 V, 25 °C - maintains signal integrity in high-impedance bias networks and sensor front-ends. |
| Package | SOT323 (SC-70) - 2.0 × 1.25 × 0.95 mm footprint ideal for space-constrained ADAS camera modules. |
Pinout & Package
Encapsulated in SOT323 (SC-70), a 3-lead surface-mount plastic package with 1.3 mm lead pitch, 2.0 mm × 1.25 mm body size, and 0.95 mm maximum height. Thermal performance rated at Rth(j-a) = 625 K/W on standard FR4 PCB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A1) | Anode of Diode 1 | Accepts forward current into first diode; used for input-side clamping or signal steering path 1. |
| 2 (A2) | Anode of Diode 2 | Independent anode for second diode; enables dual-path protection or differential signal conditioning. |
| 3 (CC) | Common Cathode | Shared cathode node - simplifies PCB layout by reducing return path count and enabling single-point grounding. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use per stress-test requirements including HTGB, HTRB, and temperature cycling - no derating needed for under-hood deployment. |
| Common-cathode dual configuration | Reduces component count and board area vs. discrete diodes; eliminates mismatch-induced timing skew between parallel paths. |
| Low trr and Cd synergy | Simultaneous ≤4 ns recovery and ≤1.5 pF capacitance enable clean edge preservation in 100+ Mbps digital signal routing. |
| High IF pulse capability | Withstands 4 A non-repetitive forward surge (tp = 1 µs), supporting ESD transient absorption without external TVS. |
Applications
| Automotive Infotainment Power Sequencing | USB 2.0 Data Line Clamping |
|---|---|
Use Scenario: Managing power-up order between head unit MCU and display driver IC during cold crank. IC Role / Device Role / Timing Role: Dual-diode clamps bidirectional I²C/SPI level-shift signals while blocking reverse current during rail ramp-up. Use Value: Prevents latch-up in mixed-voltage peripherals using single-device common-cathode topology with <4 ns response. |
Use Scenario: Protecting USB D+/D− lines from ESD and coupling noise in vehicle-mounted docking stations. IC Role / Device Role / Timing Role: Low-capacitance dual diode shunts transients to VBUS while preserving 480 Mbps data eye integrity. Use Value: 1.5 pF capacitance avoids signal rise-time degradation; AEC-Q101 rating ensures reliability across thermal cycles. |
| ADAS Camera Module Bias Networks | Engine Control Unit (ECU) Sensor Signal Conditioning |
Use Scenario: Providing stable bias to CMOS image sensor analog front-end in rear-view camera modules. IC Role / Device Role / Timing Role: Common-cathode pair isolates reference voltage from supply ripple and suppresses RF ingress on bias lines. Use Value: ≤0.5 µA leakage at 80 V prevents drift in high-impedance bias dividers; SOT323 fits tight optical module layouts. |
Use Scenario: Conditioning analog signals from knock or oxygen sensors exposed to engine bay EMI. IC Role / Device Role / Timing Role: High-speed diode pair clips induced transients before they reach ADC input stages. Use Value: 4 ns trr ensures clipping occurs within nanosecond-scale noise spikes; 150 °C Tj rating matches under-hood thermal envelope. |
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-Q | Same SOT323 package and AEC-Q101 qualification, but trr = 3 ns (faster) and VF = 1.25 V at 150 mA (higher conduction loss). | Better suited for ultra-fast digital signal clamping; less optimal for low-VF analog bias paths. | Select when trr < 3.5 ns is mandatory and forward current exceeds 50 mA. |
| MMBD7000-7-F | Non-automotive grade, SOT23 package, trr = 4 ns, VR = 100 V, but not AEC-Q101 qualified and Cd = 2.0 pF. | Limited to industrial or consumer-grade systems where automotive qualification is not required. | Choose only for cost-sensitive non-automotive designs with relaxed thermal and reliability requirements. |
Compared with BAV99W-Q and MMBD7000-7-F, the BAV70W-Q delivers optimal balance of speed (≤4 ns), low capacitance (≤1.5 pF), and automotive qualification in the smallest footprint - making it preferred for space- and reliability-critical ADAS and infotainment subsystems.

FAQ
Is BAV70W-Q pin-compatible with BAV99W-Q?
Yes - both use identical SOT323 (SC-70) package with matching pin 1 (A1), pin 2 (A2), and pin 3 (CC) assignments. Layouts designed for BAV99W-Q can be reused without modification, though thermal and electrical behavior differs slightly due to VF and trr variations.
What is the maximum continuous forward current per diode?
The absolute maximum continuous forward current per diode is 175 mA at Tamb ≤ 25 °C, as defined in Table 5 (Limiting values). Derating is required above 25 °C ambient, with total power dissipation limited to 200 mW per device on standard FR4 PCB.
Does BAV70W-Q support reflow soldering per JEDEC J-STD-020?
Yes - Nexperia specifies compatibility with standard lead-free reflow profiles per JEDEC J-STD-020. Figure 8 provides the recommended reflow soldering footprint (2.65 mm × 2.35 mm pad layout with 0.6 mm solder paste stencil openings for each of the three terminals).
Can BAV70W-Q replace BAT54S in automotive designs?
No - BAT54S uses SOT23 package and is not AEC-Q101 qualified. While both are common-cathode dual Schottky diodes, BAV70W-Q is a high-speed silicon switching diode (not Schottky), offering higher VR (100 V vs. 30 V) and AEC-Q101 compliance, but higher VF. Direct replacement requires validation of circuit voltage and thermal margins.
