Product details
Overview
BAS40-06/ZLR from Nexperia is a dual Schottky barrier diode in SOT-363 (SC-88) package, rated at 40 V reverse voltage, 200 mA average forward current per anode, and 1.25 V max forward voltage at 200 mA. It serves as high-speed switching and clamping diode in low-voltage DC-DC converter feedback paths and USB port protection circuits.
For engineers reviewing the BAS40-06/ZLR datasheet, BAS40-06/ZLR pinout, BAS40-06/ZLR application, or BAS40-06/ZLR equivalent, key selection criteria include dual-anode common-cathode configuration, low VF for efficiency-sensitive 3.3 V/5 V rail clamping, fast trr ≤ 5 ns, and AEC-Q101 qualification for automotive infotainment power management.
Technical Context
This dual Schottky diode integrates two independent anodes sharing one cathode terminal, enabling compact dual-rail clamping or OR-ing functions without external wiring. Its epitaxial silicon structure delivers low leakage (IR ≤ 100 nA at 25 °C) and stable VF across -55 °C to +150 °C junction temperature range.
The device operates with minimal stored charge (QRR ≤ 1.5 pC), supporting >10 MHz switching in synchronous rectifier auxiliary paths. Its SOT-363 footprint matches JEDEC MO-203-DA standard and supports reflow soldering per IPC/JEDEC J-STD-020D.3.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (max) | 40 V - supports clamping of 3.3 V and 5 V logic rails against transient overshoot up to 40 V |
| IF(AV) per anode | 200 mA - sufficient for USB 2.0 data line ESD clamp bias and low-power signal path steering |
| VF @ 200 mA | 1.25 V max - enables <100 mW conduction loss per diode at full rated current in 5 V systems |
| trr | 5 ns max - ensures clean edge transition in 10–20 MHz clock buffer output clamping |
| IR @ VR | 100 nA max @ 25 °C - maintains signal integrity in high-impedance analog sensor interface nodes |
| Junction Temp | -55 °C to +150 °C - qualified for under-hood automotive modules and industrial PLC I/O stages |
Pinout & Package
SOT-363 (SC-88) 6-pin plastic surface-mount package, 2.1 mm × 2.0 mm × 0.95 mm body, gull-wing leads, lead pitch 0.65 mm. Moisture sensitivity level (MSL) 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode 1 | First Schottky junction input; connects to protected signal or supply rail needing clamping |
| 2 | Cathode | Common cathode node shared by both diodes; ties to system ground or reference rail |
| 3 | Anode 2 | Second independent Schottky junction input; used for dual-rail or redundant clamping |
| 4 | No Connect | Internally unconnected; must be left floating or tied to cathode only if PCB layout requires symmetry |
| 5 | Cathode | Redundant cathode bond wire; electrically identical to Pin 2, improves thermal and current sharing |
| 6 | No Connect | Internally unconnected; no electrical function; may be grounded for mechanical stability |
Key Features
| Feature | Design Value |
|---|---|
| Dual-anode common-cathode topology | Enables space-efficient dual-rail clamping in single 2.1×2.0 mm footprint without discrete pairing |
| AEC-Q101 qualified | Validated for automotive power management modules requiring zero early-life failure in temperature cycling |
| Low QRR (≤1.5 pC) | Minimizes reverse recovery noise in high-frequency switching nodes like buck converter feedback dividers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky clamping applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MBR0540T1G | Single-anode TO-236 package; higher VF (0.55 V @ 0.5 A); no dual-anode integration | Requires two devices and extra PCB area for dual-rail use; better suited for high-current single-rail rectification | Select when >200 mA per rail is needed and board space allows discrete placement |
| NSR0240HT1G | Single-channel SOD-523; 200 mA rating; VF = 0.5 V @ 100 mA; no common-cathode dual configuration | Lacks integrated dual-anode functionality; unsuitable for simultaneous dual-rail clamping | Choose only for single-signal-line protection where ultra-small size outweighs dual functionality |
Compared with MBR0540T1G and NSR0240HT1G, BAS40-06/ZLR uniquely delivers dual-anode clamping in one SOT-363 device-reducing component count by 50% and PCB area by 60% versus dual-single solutions-while maintaining AEC-Q101 compliance for automotive deployment.

FAQ
What is the maximum peak forward surge current (IFSM) for BAS40-06/ZLR?
The BAS40-06/ZLR has a non-repetitive peak forward surge current rating of 600 mA per anode, tested with a single half-sine wave pulse of 10 ms duration at 25 °C ambient. This rating supports brief inrush events during hot-plug insertion in USB interfaces and ensures robustness against short-duration load transients in automotive power domains.
Is BAS40-06/ZLR compatible with lead-free reflow profiles?
Yes. BAS40-06/ZLR is qualified for lead-free reflow soldering per IPC/JEDEC J-STD-020D.3, with peak temperature tolerance up to 260 °C for 30 seconds. Its MSL 1 rating permits unlimited exposure to ambient conditions prior to assembly, eliminating pre-bake requirements and simplifying high-mix manufacturing workflows.
Can Pin 4 and Pin 6 be used as thermal pads or grounded for improved heat dissipation?
No. Pins 4 and 6 are internally unconnected and serve no electrical or thermal function. Connecting them to ground or thermal planes provides no thermal benefit and risks solder bridging or unintended parasitic coupling. Thermal performance relies solely on the cathode pins (2 and 5) and PCB copper area beneath the package body.
How does the dual-anode configuration affect leakage current in high-impedance sensor applications?
Each anode exhibits independent reverse leakage (IR ≤ 100 nA at 25 °C, VR = 40 V), with no coupling between channels. In high-impedance sensor interfaces, this ensures leakage remains below 200 nA total even when both anodes are biased, preserving measurement accuracy in µA-range current loops and high-resistance voltage dividers.
