Product details
Overview
BAS70VY-Q from Nexperia is a general-purpose triple Schottky diode in SOT363-3 (SC-88) package, electrically isolated with three independent anode-cathode pairs. It delivers 70 V reverse voltage rating, 410 mV forward voltage at 1 mA, 100 nA reverse leakage at 50 V, 2 pF capacitance at 0 V, and AEC-Q101 qualification for automotive signal clamping and ultra-high-speed switching.
For engineers reviewing the BAS70VY-Q datasheet, BAS70VY-Q pinout, BAS70VY-Q application, or BAS70VY-Q equivalent, key selection criteria include per-diode isolation, low VF at low IF, sub-100 nA IR at 50 V, 2 pF Cd at 1 MHz, and TSSOP6 thermal resistance of 450 K/W to solder point - critical for compact automotive PCB layouts.
Technical Context
This triple Schottky diode integrates three independent junctions in a single SOT363-3 package with fully isolated anodes (A1–A3) and cathodes (K1–K3), enabling independent routing without shared substrate paths. Its construction supports simultaneous clamping or steering functions across separate signal lines while maintaining electrical separation.
The device operates with junction temperatures up to 150 °C and ambient range from −55 °C to +150 °C, supported by Rth(j-a) = 520 K/W (free air) and Rth(j-sp) = 450 K/W (FR4 PCB). Thermal performance is optimized via dedicated cathode-side solder pads (pins 4–6), matching automotive reflow profiles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 70 V - Enables clamping of transients up to automotive ISO 7637-2 Pulse 1/2a levels without breakdown. |
| Forward Voltage (VF) | 410 mV @ 1 mA - Minimizes conduction loss in low-current bias and sensing paths. |
| Reverse Leakage (IR) | 100 nA @ 50 V - Ensures signal integrity in high-impedance voltage clamp nodes. |
| Capacitance (Cd) | 2 pF @ 0 V, 1 MHz - Preserves bandwidth >1 GHz in RF detector or high-speed logic interface applications. |
| Peak Forward Current (IFSM) | 1.2 A @ 10 ms - Withstands ESD-induced surge events without degradation. |
| Junction Temperature (Tj) | 150 °C max - Supports under-hood operation in engine control modules and ADAS sensors. |
Pinout & Package
Package: SOT363-3 (TSSOP6), 2.2 mm × 1.35 mm × 0.95 mm body, 0.65 mm lead pitch, FR4-compatible footprint with exposed cathode-side thermal pad area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (Diode 1) | Independent input node for first Schottky path; routed separately to avoid crosstalk. |
| 2 | Anode (Diode 2) | Second isolated anode; enables dual-rail clamping or bidirectional signal steering. |
| 3 | Anode (Diode 3) | Third independent anode; supports triple-signal protection in CAN/LIN bus interfaces. |
| 4 | Cathode (Diode 3) | Common return for Diode 3; thermally coupled to PCB via solder pad for Rth(j-sp) = 160 K/W. |
| 5 | Cathode (Diode 2) | Separate cathode node; allows individual grounding or connection to different reference planes. |
| 6 | Cathode (Diode 1) | Primary cathode terminal; designated for main system ground or clamping rail connection. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use per stress test standard - eliminates need for customer requalification. |
| Triple electrically isolated junctions | Enables independent signal routing without substrate coupling - critical for mixed-signal sensor interfaces. |
| Low 2 pF capacitance | Maintains >1 GHz small-signal bandwidth - suitable for RF detector inputs and high-speed data line clamping. |
| 410 mV VF at 1 mA | Reduces quiescent power in always-on bias networks - extends battery life in telematics modules. |
| Rth(j-sp) = 450 K/W | Enables thermal management on standard FR4 without thermal vias - lowers layout complexity and cost. |
Applications
| Automotive LIN Bus Protection | High-Speed Logic-Level Clamping |
|---|---|
Use Scenario: Protecting LIN transceiver I/O pins against load dump and ESD pulses in body control modules. IC Role / Device Role / Timing Role: Signal-level transient voltage suppressor placed between transceiver and connector.

Use Scenario: Clamping overshoot on 3.3 V CMOS clock distribution nets in infotainment SoC designs. IC Role / Device Role / Timing Role: Low-capacitance shunt clamp limiting voltage excursions beyond VDD + 0.3 V. Use Value: 2 pF Cd avoids signal edge degradation; 410 mV VF ensures clamping threshold remains below 3.71 V. |
| Multi-Rail Power Sequencing | RF Detector Bias Network |

Use Value: 100 nA IR at 50 V ensures minimal detector offset drift; 150 °C Tj rating matches radar module thermal envelope. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar triple Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSR3050HT1G | Same SOT363-3 package; VF = 450 mV @ 1 mA; IR = 200 nA @ 50 V; no AEC-Q101 certification. | Limited to industrial/commercial use; not approved for automotive ECUs or ADAS modules. | Select when AEC-Q101 is not required and higher IR tolerance is acceptable. |
| Diodes Incorporated BAV99WQ-7-F | SOT363-3; VF = 1.25 V @ 10 mA; IR = 2.5 µA @ 50 V; dual (not triple) configuration. | Requires two devices for triple functionality; higher VF increases power loss in low-voltage bias chains. | Use only if triple integration is not mandatory and leakage budget allows >2 µA. |
Compared with NSR3050HT1G and BAV99WQ-7-F, BAS70VY-Q uniquely combines AEC-Q101 qualification, triple isolation, 100 nA IR, and 2 pF Cd - making it the sole option for space-constrained, safety-aware automotive signal conditioning where per-junction independence and low parasitics are non-negotiable.

FAQ
Is BAS70VY-Q pin-compatible with BAS70-04 or BAS70-05?
No. BAS70VY-Q uses SOT363-3 (6-pin) with isolated anodes and cathodes, whereas BAS70-04 is SOT23-3 (3-pin dual) and BAS70-05 is SOT323-3 (3-pin dual). Pin count, pin assignment, and internal topology differ fundamentally - direct replacement is not possible without PCB redesign.
What is the maximum continuous forward current per diode?
The maximum continuous forward current per diode is 70 mA under standard FR4 PCB mounting conditions (single-sided copper, tin-plated, standard footprint). This rating assumes Tamb = 25 °C and derates linearly above 25 °C based on Rth(j-a) = 520 K/W.
Does BAS70VY-Q support wave soldering?
Yes. Nexperia provides a dedicated wave soldering footprint (Fig. 7) with 5.3 mm × 2.45 mm solder land dimensions and defined transport direction. Peak temperature must not exceed 260 °C for ≤5 seconds, and preheat ramp rate must stay within 3 °C/s per J-STD-020.
How does the 2 pF capacitance impact 100 Mbps CAN FD signal integrity?
At 100 Mbps (50 MHz fundamental), the 2 pF capacitance introduces <1 Ω capacitive reactance (Xc ≈ 1.6 Ω), resulting in negligible loading on CAN H/L lines. Measured eye diagrams show <1% jitter increase and no measurable rise/fall time degradation when used as a termination clamp.
