Product details
Overview
BAV70SRA from Nexperia is a quad high-speed switching diode array with two common-cathode dual-diode sections (D1/D2 sharing K1,2; D3/D4 sharing K3,4), housed in a DFN1412-6 (SOT1268) package. It delivers trr ≤ 4 ns reverse recovery time, VR = 100 V, IF = 355 mA per diode, and Cd ≤ 1.5 pF - enabling compact, low-capacitance signal routing in automotive and industrial high-frequency switching circuits.
For engineers reviewing the BAV70SRA datasheet, BAV70SRA pinout, BAV70SRA application, or BAV70SRA equivalent, this device is selected for AEC-Q101-compliant high-speed discrete switching where space-constrained layouts demand ultra-small thermal-enhanced SMD packaging and sub-4 ns recovery performance.
Technical Context
The BAV70SRA integrates four independent silicon switching diodes in a single 1.4 mm × 1.2 mm DFN1412-6 package, configured as two electrically isolated dual-diode groups with shared cathodes. Each diode exhibits VF = 855 mV at IF = 10 mA and IR ≤ 0.5 µA at VR = 80 V, supporting fast transient response in clamping and steering functions.
Its thermal design targets junction-to-solder-point resistance of 205 K/W and junction-to-ambient of 305 K/W on FR4 PCBs, while AEC-Q101 qualification confirms suitability for under-hood automotive environments up to Tj = 150 °C and Tamb = −55 °C to +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Recovery Time | trr ≤ 4 ns - enables operation in >100 MHz switching nodes without tail current delay |
| Peak Reverse Voltage | VR = 100 V - supports 48 V automotive bus transients and industrial 24/48 V supply rail protection |
| Forward Current (per diode) | IF = 355 mA - sufficient for logic-level signal routing and moderate-power clamp duty |
| Diode Capacitance | Cd ≤ 1.5 pF at VR = 0 V, f = 1 MHz - minimizes signal distortion in RF and high-speed digital interfaces |
| Leakage Current | IR ≤ 0.5 µA at VR = 80 V, Tj = 25 °C - ensures low standby power loss in always-on sensing paths |
| Junction Temperature Limit | Tj(max) = 150 °C - validated for continuous operation in engine control units and ADAS modules |
| AEC-Q101 Qualified | Qualified per Stress Test Qualification for Discrete Semiconductors - meets automotive reliability requirements |
Pinout & Package
Package: DFN1412-6 (SOT1268), ultra-thin surface-mount plastic package, 1.4 mm × 1.2 mm × 0.47 mm body, thermal-enhanced cathode pad, leadless.
| Pin/Terminal | Circuit Role | Design Meaning |

| 4 | Anode (Diode 3) | Anode of third diode, paired with Pin 5's anode under shared cathode (Pin 3) |
| 5 | Anode (Diode 4) | Anode of fourth diode, completing second dual-diode group with Pin 4 and Pin 3 |
| 6 | Common Cathode (Diodes 1 & 2) | Shared return for Diodes 1 and 2; electrically isolated from Pin 3; requires separate PCB trace |
Key Features
| Feature | Design Value |
|---|---|

Applications
| Automotive Signal Clamping | Industrial Digital I/O Protection |
|---|---|
Use Scenario: Protecting LIN bus transceivers against load-dump transients and ESD events in body control modules. IC Role / Device Role / Timing Role: Fast clamping diode array shunting overvoltage spikes to ground before IC input stages are damaged. Use Value: 4 ns recovery and 100 V VR withstand capability prevent false triggering and latch-up during 12 V/24 V vehicle battery surges. |

IC Role / Device Role / Timing Role: Quad diode array used in series-shunt configuration to limit input voltage swing and absorb inductive kickback. Use Value: Dual common-cathode structure allows independent channel protection with shared ground return, reducing component count by 50% vs. discrete diodes. |
| High-Frequency Clock Steering | USB 2.0 Data Line ESD Suppression |
Use Scenario: Selecting between two clock sources in FPGA-based timing subsystems using diode-OR logic. IC Role / Device Role / Timing Role: High-speed switching diode performing low-latency signal steering without active control. Use Value: 1.5 pF capacitance and <1 V forward drop preserve clock edge fidelity up to 100 MHz without measurable jitter degradation. |
Use Scenario: Adding secondary ESD protection on USB 2.0 D+ and D− lines downstream of primary TVS arrays. IC Role / Device Role / Timing Role: Low-capacitance switching diode providing fast turn-on clamping for ±8 kV contact discharge events. Use Value: Sub-4 ns trr ensures clamping activation occurs before data eye closure, maintaining signal integrity across full-speed (12 Mbps) USB links. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed discrete diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99S | Same DFN1412-6 package but dual-diode (not quad); trr = 4 ns, VR = 70 V, IF = 215 mA | Limited to two-channel protection; lower VR reduces margin in 48 V systems | Select when only two high-speed paths are needed and board space permits separate dual-diode placement |
| NSR0230P2T5G | Single Schottky diode in SOD-923; VF = 0.3 V typical, trr not specified, VR = 30 V | No quad integration; lacks common-cathode grouping; unsuitable for >30 V rails | Choose only for ultra-low VF requirements in low-voltage (<3.3 V) logic-level clamping where speed is secondary |
Compared with BAV99S and NSR0230P2T5G, the BAV70SRA uniquely provides four independently switchable diodes in one AEC-Q101-qualified package with 100 V rating and verified 4 ns recovery - making it the only option for space-constrained, high-reliability quad-switching applications in automotive and industrial control.

FAQ
What is the maximum allowable ambient temperature for continuous operation?
The BAV70SRA supports continuous operation from −55 °C to +150 °C ambient temperature. Derating begins above 25 °C: at 125 °C ambient, maximum per-diode forward current drops to 210 mA for double-diode loading, per Figure 1 in the datasheet. Thermal design must account for Rth(j-a) = 305 K/W on standard FR4.
Can Pins 3 and 6 be connected to the same ground plane?
No - Pins 3 (K3,4) and 6 (K1,2) are electrically isolated common cathodes for separate diode pairs. Connecting them violates the internal die layout and may cause unintended current sharing, thermal imbalance, or failure to meet trr ≤ 4 ns specifications. They require independent PCB traces routed to appropriate reference nodes.
Is the BAV70SRA suitable for bidirectional ESD protection?
No - the BAV70SRA is a unidirectional switching diode array with anode-cathode polarity. For bidirectional ESD protection, complementary TVS diodes or dedicated ESD arrays (e.g., PESD5V0S1BA) are required. Its role is clamping positive transients to ground, not symmetric ±8 kV suppression.
How does the DFN1412-6 package affect solder reflow profile requirements?
The DFN1412-6 package requires precise reflow profiling due to its thermal-enhanced cathode pad and ultra-thin 0.47 mm profile. Peak temperature must reach 260 °C for ≤10 s, with ramp rates limited to ≤3 °C/s pre-peak and ≥6 °C/s cooling. Figure 11 specifies a 1.23 mm × 0.43 mm solder land for the cathode pad to ensure void-free wetting and thermal reliability.
