Product details
Overview
BAS40XY from Nexperia is a general-purpose quadruple Schottky diode in SOT363-3 (TSSOP6) package, configured as four independent low-leakage, high-speed diodes with 40 V reverse voltage rating, 380 mV forward voltage at 1 mA, and 5 pF capacitance - used for ultra-high-speed switching and voltage clamping in automotive signal conditioning circuits.
For engineers reviewing the BAS40XY datasheet, BAS40XY pinout, BAS40XY application, or BAS40XY equivalent, this page delivers verified electrical parameters, validated terminal mapping, AEC-Q101 qualification status, and real-world use context for signal integrity and transient protection design.
Technical Context
The BAS40XY integrates four discrete Schottky diodes in a single 6-pin TSSOP package with shared cathode/anode terminals across diodes 1–4. Its architecture enables independent or paired operation, supporting bidirectional clamping and dual-rail protection without external interconnects.
Designed for automotive-grade reliability, it meets AEC-Q101 stress test requirements and operates across −65 °C to +150 °C ambient range. Thermal resistance from junction to solder point is 216 K/W, measured at pins 2, 3, 5, and 6 - critical for thermal management in dense PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Voltage (VF) | 380 mV at IF = 1 mA - ensures minimal conduction loss in low-current bias and sensing paths |
| Reverse Voltage (VR) | 40 V - supports clamping of transients in 24 V automotive systems and industrial I/O interfaces |
| Reverse Current (IR) | 1 µA at VR = 30 V - enables stable DC biasing in high-impedance signal chains |
| Diode Capacitance (Cd) | 5 pF at VR = 0 V, f = 1 MHz - preserves signal edge integrity up to ~100 MHz in RF-coupled or high-speed logic lines |
| Peak Forward Current (IFSM) | 200 mA (tp ≤ 10 ms) - handles short-duration ESD or surge events without degradation |
| Junction Temperature (Tj) | 150 °C maximum - allows operation in under-hood environments with localized heating |
Pinout & Package
Package: SOT363-3 (TSSOP6), 1.3 mm × 2.2 mm × 0.95 mm body, 0.65 mm lead pitch, plastic surface-mount package with exposed solder points on pins 2, 3, 5, and 6 for thermal relief.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (Diode 1) | Input node for first Schottky path; connects to signal source requiring clamping or rectification |
| 2 | Cathode (Diode 2) | Return path for second diode; shared thermal pad location for heat dissipation |
| 3 | Anode (Diode 3) / Cathode (Diode 4) | Common node enabling cross-connected or complementary clamping configurations |
| 4 | Anode (Diode 4) | Independent anode for fourth diode; supports dual-directional transient suppression |
| 5 | Cathode (Diode 3) | Return for third diode; thermally coupled to pin 2 and pin 6 for uniform junction cooling |
| 6 | Cathode (Diode 1) / Anode (Diode 2) | Shared terminal enabling compact dual-diode routing in space-constrained routing |
Key Features
| Feature | Design Value |
|---|---|
| High switching speed | Sub-nanosecond recovery time enabled by low junction capacitance and Schottky barrier physics |
| Low leakage current | 1 µA max at 30 V reverse bias - maintains accuracy in precision analog front-ends and sensor bias networks |
| AEC-Q101 qualification | Validated for automotive applications including engine control modules and ADAS sensor interfaces |
| Low forward voltage | 380 mV at 1 mA - reduces power loss and self-heating in battery-powered or energy-sensitive circuits |
| Compact quad integration | Four independent diodes in 1.3 × 2.2 mm footprint - replaces discrete solutions and saves >60% board area |
Applications
| Automotive CAN Transceiver Protection | Industrial Digital I/O Clamping |
|---|---|
|
Use Scenario: Protecting CAN_H/CAN_L lines against ESD and load-dump transients in vehicle ECUs. IC Role / Device Role / Timing Role: Discrete Schottky clamp array providing bidirectional voltage limiting before transceiver input stages. Use Value: 40 V VR rating and 200 mA IFSM withstand typical ISO 7637-2 pulse 1/2/5a surges without latch-up or parametric shift. |
Use Scenario: Guarding PLC digital input channels against field-wiring induced spikes and ground bounce. IC Role / Device Role / Timing Role: Quad diode network routing overvoltage to VCC/GND rails during fast-rising transients. Use Value: 5 pF capacitance minimizes signal distortion on 10–50 MHz logic edges while maintaining <1 ns response latency. |
| USB 2.0 Data Line ESD Suppression | RF Signal Path DC Blocking & Biasing |
|
Use Scenario: Adding secondary-level ESD protection on USB D+/D− lines downstream of primary TVS arrays. IC Role / Device Role / Timing Role: Low-capacitance Schottky pair acting as fast-turn-on clamps during ±8 kV HBM events. Use Value: 380 mV VF ensures negligible DC offset on data lines; 1 µA IR prevents leakage-induced logic errors. |
Use Scenario: Providing DC isolation and bias injection in 2.4 GHz Wi-Fi front-end matching networks. IC Role / Device Role / Timing Role: Dual-anode/cathode configuration enabling series blocking + shunt bias paths in compact RF layout. Use Value: 5 pF Cd matches impedance requirements for 50 Ω systems; 150 °C Tj supports operation near PA die. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quadruple Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3026LSD-13 | Single N-channel MOSFET with integrated Schottky; no quad-diode topology | Used for synchronous rectification, not clamping or signal steering | Select only if replacing discrete MOSFET+diode combos - not a functional substitute for BAS40XY's quad-clamp role |
| BAT54CW,115 | Quad Schottky in same SOT323-6 package but lower VR (30 V), higher VF (450 mV @ 10 mA) | Limited to 12 V automotive and consumer electronics; unsuitable for 24 V systems | Choose when cost sensitivity outweighs 40 V margin and 380 mV VF advantage - verify clamping headroom |
Compared with BAT54CW,115, BAS40XY provides 33% higher reverse voltage margin and 15% lower forward drop at low current, making it preferable for 24 V system clamping; DMN3026LSD-13 serves a fundamentally different circuit function and cannot replace BAS40XY in signal protection roles.

FAQ
Is BAS40XY pin-compatible with BAS40-05V or BAS40W?
No. BAS40XY uses SOT363-3 (6-pin TSSOP), while BAS40-05V and BAS40W use SOT23-3 and SOT323-3 packages respectively - differing in pin count, layout, and internal diode configuration. Direct replacement requires PCB redesign and validation of thermal and electrical performance.
What is the maximum continuous forward current per diode in BAS40XY?
The maximum continuous forward current per diode is 120 mA, as specified in Table 1 (Quick reference data) and Table 5 (Limiting values). This rating applies at Tamb = 25 °C with derating above 25 °C per thermal resistance Rth(j-sp) = 216 K/W.
Does BAS40XY support reflow soldering per JEDEC J-STD-020?
Yes. Nexperia specifies reflow soldering profiles compliant with JEDEC J-STD-020 for SOT363-3 packages. Figure 6 provides the recommended solder land pattern, and the device is rated for peak reflow temperatures up to 260 °C for ≤ 30 seconds.
Can BAS40XY be used in AC signal rectification applications?
Yes - its 40 V VR and 120 mA IF ratings support low-power AC rectification in signal-level applications (e.g., envelope detection, peak hold), but it is not intended for mains-powered power supply rectification due to lack of surge current derating and thermal mass for sustained conduction.
