Product details
Overview
BAS40VY from Nexperia is a general-purpose triple Schottky diode in SOT363-3 (SC-88) package, electrically isolated per diode, rated for 40 V reverse voltage, 120 mA forward current, and 380 mV forward voltage at 1 mA, used in ultra high-speed switching and voltage clamping circuits on compact PCBs.
For engineers reviewing the BAS40VY datasheet, BAS40VY pinout, BAS40VY application, or BAS40VY equivalent, key selection criteria include per-diode isolation, low 5 pF capacitance at 0 V, 1 µA reverse leakage at 30 V, thermal resistance of 440 K/W to solder point, and compatibility with reflow/wave soldering footprints for space-constrained designs.
Technical Context
This triple Schottky diode integrates three independent anode–cathode pairs in a single surface-mount package, with no internal connection between diodes-enabling flexible routing in multi-rail clamping or signal steering. Each diode exhibits fast switching due to low junction capacitance (5 pF) and low forward voltage (380 mV @ 1 mA).
Thermal performance is defined by junction-to-solder-point resistance of 440 K/W under specified FR4 mounting conditions, supporting reliable operation up to 150 °C junction temperature. The device operates within −55 °C to +150 °C ambient range and withstands non-repetitive peak forward current up to 1.5 A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - Maximum blocking voltage per diode before breakdown; defines safe operating range in clamping or reverse-polarity protection. |
| Forward Current (IF) | 120 mA - Continuous DC current rating per diode; supports moderate signal-level switching without derating on standard FR4. |
| Forward Voltage (VF) | 380 mV @ 1 mA - Low conduction loss at light load; critical for battery-powered logic-level clamping and low-power signal routing. |
| Reverse Leakage (IR) | 1 µA @ 30 V - Minimal off-state current; preserves signal integrity in high-impedance nodes and reduces standby power loss. |
| Capacitance (Cd) | 5 pF @ 0 V, 1 MHz - Enables >100 MHz signal handling; suitable for RF detector inputs and high-speed data line protection. |
| Thermal Resistance (Rth(j-sp)) | 440 K/W - Junction-to-solder-point value under defined FR4 pad layout; informs thermal design margin for sustained 120 mA operation. |
Pinout & Package
Package: SOT363-3 (TSSOP6), 1.3 mm × 2.2 mm × 0.95 mm body height, 0.65 mm lead pitch, plastic surface-mount package with exposed cathode-side thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A1 | Anode of Diode 1 - Connects to positive side of first independent Schottky path; routed separately for isolation-critical applications. |
| 2 | A2 | Anode of Diode 2 - Electrically isolated anode node; enables dual-rail clamping or independent signal steering without crosstalk. |
| 3 | A3 | Anode of Diode 3 - Third isolated anode terminal; supports triple-voltage rail conditioning or redundant protection paths. |
| 4 | K3 | Cathode of Diode 3 - Common cathode-side connection point for third diode; shares thermal pad with pins 5 and 6 for improved heat dissipation. |
| 5 | K2 | Cathode of Diode 2 - Independent cathode node; allows individual cathode biasing or separate return paths in multi-channel systems. |
| 6 | K1 | Cathode of Diode 1 - First cathode terminal; designated pin 6 in TSSOP6 outline; aligned with standard SOT363-3 footprint for automated assembly. |
Key Features
| Feature | Design Value |
|---|---|
| Triple electrically isolated diodes | Enables independent routing of three signal or power paths without shared junctions-critical for mixed-voltage domain clamping. |
| Low 5 pF capacitance | Minimizes signal distortion and timing skew in >100 MHz digital or RF interface lines, including USB 2.0 and LVDS receivers. |
| 380 mV VF @ 1 mA | Reduces voltage drop in low-current logic-level translation or ESD clamp bias networks, preserving noise margins in 1.8 V/3.3 V systems. |
| 1 µA IR @ 30 V | Ensures negligible leakage in high-impedance sample-and-hold or analog switch control lines, preventing drift or false triggering. |
Applications
| USB 2.0 Data Line Protection | Multi-Rail Power Sequencing |
|---|---|
Use Scenario: Clamping transient overvoltage on D+ and D− lines during hot-plug events while maintaining signal integrity. IC Role / Device Role / Timing Role: Discrete Schottky clamp diode pair (D1/D2) with third diode (D3) for VBUS monitoring or auxiliary bias. Use Value: 5 pF capacitance avoids signal rise-time degradation; 380 mV VF ensures clamping threshold stays below 0.7 V, protecting 3.3 V transceivers. | Use Scenario: Controlling power-up order across 1.2 V, 1.8 V, and 3.3 V rails using diode-OR'd enable signals with independent thresholds. IC Role / Device Role / Timing Role: Triple-anode configuration allows separate anode connections to each rail's enable output, with shared cathode return. Use Value: Electrical isolation prevents backfeed between rails; 40 V VR rating accommodates margin above highest rail voltage. |
| LVDS Receiver Input Clamp | Low-Power Logic-Level Translation |
Use Scenario: Protecting differential receiver inputs against ESD and overshoot in industrial fieldbus interfaces. IC Role / Device Role / Timing Role: One diode per input (D1/D2) clamps to local supply/GND; third diode (D3) provides reference or bias path. Use Value: 1 µA IR preserves high-impedance termination; low VF avoids false triggering of internal receiver comparators. | Use Scenario: Translating 1.8 V GPIO outputs to 3.3 V logic inputs in battery-powered IoT sensors. IC Role / Device Role / Timing Role: Anode tied to 1.8 V source, cathode pulled to 3.3 V rail via resistor-Schottky forward drop sets translation threshold. Use Value: 380 mV VF yields ~2.18 V output swing, meeting 3.3 V VIH minimum; triple configuration supports three independent I/O channels. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar triple Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3026LSD-13 | Single-channel dual-Schottky in SOT23-6; no per-diode isolation; higher VF (450 mV @ 1 mA). | Not suitable for independent rail clamping; limited to paired-channel use only. | Select only when board space permits larger SOT23-6 and electrical isolation is unnecessary. |
| RB050M-30 | Triple Schottky in SOT-363 but with common cathode; 30 V VR rating; 10 pF capacitance. | Lower voltage rating restricts use to ≤3.3 V systems; higher capacitance limits >50 MHz applications. | Prefer for cost-sensitive 3.3 V-only designs where 40 V margin and 5 pF are not required. |
Compared with DMN3026LSD-13 and RB050M-30, BAS40VY uniquely delivers per-diode isolation, 40 V blocking, and 5 pF capacitance in SOT363-3-making it optimal for multi-rail, high-speed, and space-constrained clamping where channel independence and bandwidth matter.

FAQ
What is the maximum continuous forward current per diode in BAS40VY?
The maximum continuous forward current per diode is 120 mA under standard FR4 PCB mounting conditions (single-sided copper, tin-plated, standard footprint). This rating assumes one diode is loaded at a time; simultaneous conduction across all three diodes requires thermal derating based on Rth(j-sp) = 440 K/W and ambient temperature limits.
Can BAS40VY be used in automotive applications?
No-BAS40VY is not automotive-qualified. Nexperia explicitly states in its legal disclaimers that unless a product data sheet expressly declares automotive qualification, the device is neither tested nor warranted for automotive use. It lacks AEC-Q101 stress testing and is intended for industrial, consumer, and computing applications only.
How does the pin configuration support independent diode operation?
Pins 1–3 are dedicated anodes (A1–A3) and pins 4–6 are dedicated cathodes (K3–K1), with no internal connection between any anode and cathode except within each diode pair. This full electrical isolation allows each diode to operate with different bias voltages, currents, or signal domains-essential for multi-rail clamping or independent signal routing.
What is the recommended soldering profile for BAS40VY?
The manufacturer specifies reflow soldering using the footprint in Figure 6 (sot363-3_fr), with solder paste stencil apertures sized for 0.5 mm × 0.5 mm pads (4×), 0.6 mm × 0.6 mm pads (4×), and 0.4 mm × 0.4 mm pads (2×). Peak reflow temperature must not exceed 260 °C for ≤10 seconds, per JEDEC J-STD-020.
