Product details

Overview

BAS40-05/DG/B2,235 from Nexperia is a dual Schottky barrier diode in SOT-323 package, rated for 40 V reverse voltage, 200 mA average forward current, and 1.25 V max forward voltage at 200 mA, used in high-speed switching and polarity protection circuits in portable power management.

For engineers reviewing the BAS40-05/DG/B2,235 datasheet, BAS40-05/DG/B2,235 pinout, BAS40-05/DG/B2,235 application, or BAS40-05/DG/B2,235 equivalent, key selection criteria include low forward voltage drop, fast recovery time (<5 ns), dual common-cathode configuration, and SOT-323 thermal performance in space-constrained DC-DC converter designs.

Technical Context

This dual Schottky diode integrates two anodes sharing a single cathode terminal, enabling compact OR-ing and reverse-polarity protection in dual-rail systems. Its low junction capacitance (2 pF at 0 V) and fast switching support operation up to 100 MHz in RF detector and signal clamping applications.

The device uses epitaxial planar technology with platinum silicide contact, delivering stable forward voltage across -65 °C to +150 °C ambient range and meeting AEC-Q101 stress test requirements for automotive-grade reliability.

Key Specifications

Parameter	Value and Actual Design Meaning
Max Reverse Voltage	40 V - supports input rails up to 36 V nominal without breakdown in USB-C PD or battery backup circuits
Avg Forward Current	200 mA per diode - sufficient for biasing, level-shifting, and low-power signal routing
Forward Voltage	1.25 V @ 200 mA - minimizes conduction loss in 3.3 V/5 V logic interface protection
Reverse Recovery Time	<5 ns - enables clean switching in high-frequency DC-DC feedback paths
Junction Capacitance	2 pF @ 0 V - preserves signal integrity in RF envelope detection and mixer applications
Operating Temp Range	−65 °C to +150 °C - qualified for under-hood automotive and industrial control environments

Pinout & Package

Package: SOT-323 (SC-70), 3-terminal surface-mount plastic package with standard lead finish and moisture sensitivity level MSL3.

Pin/Terminal	Circuit Role	Design Meaning
Anode 1 (Pin 1)	Input anode of first diode	Accepts positive input for independent forward conduction path #1
Cathode (Pin 2)	Shared cathode node	Common return path for both diodes; must be connected to system ground or reference rail
Anode 2 (Pin 3)	Input anode of second diode	Enables dual-input OR-ing or redundant supply selection without external wiring

Key Features

Feature	Design Value
Dual common-cathode configuration	Reduces PCB footprint by 40% vs. two discrete SOT-23 Schottkys; simplifies layout in dual-supply monitoring
AEC-Q101 qualified	Validated for automotive powertrain and body electronics with zero early-life failure in HTOL testing
Low leakage current	≤50 nA @ 25 °C - maintains battery standby life >10 years in always-on sensor nodes
ESD rating	HBM ±8 kV - eliminates need for external TVS in handheld device I/O protection

Applications

Automotive Body Control Module

Use Scenario: Dual-input USB-C PD source selection with reverse-current blocking.

IC Role / Device Role / Timing Role: Common-cathode Schottky OR-ing diode preventing backfeed between primary and backup power rails.

Use Value: Eliminates need for active MOSFET controllers while maintaining <1.3 V dropout at 200 mA load.

Use Scenario: Reverse-polarity protection for LIN transceiver power supply.

IC Role / Device Role / Timing Role: Input rectifier protecting 12 V supply rail against accidental battery reversal during service.

Use Value: Survives −14 V reverse bias indefinitely with leakage <100 nA at 85 °C.

RF Signal Detector

Industrial Sensor Node Power Conditioning

Use Scenario: Envelope detection in 2.4 GHz ISM-band receiver front-end.

IC Role / Device Role / Timing Role: Low-capacitance Schottky clamp converting RF amplitude to DC baseband voltage.

Use Value: 1.25 V forward drop ensures RTC remains powered down to 2.8 V battery voltage.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual Schottky diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ON Semiconductor NSR20F40NXT5G	Single-diode SOD-123FL package; 40 V, 2 A rating; higher current but no dual configuration	Requires two devices for dual-path use; larger footprint and extra routing	Select when >200 mA per path is required and board area is not constrained
Vishay SDM10030C-7-F	SOT-23 package; dual common-anode; 30 V rating; 1.1 V VF @ 200 mA	Lower voltage rating limits use in 36 V automotive systems; anode-common topology requires redesign of OR-ing net	Prefer only in 24 V industrial systems where lower VF justifies topology change

Compared with BAS40-05/DG/B2,235, NSR20F40NXT5G offers higher current headroom but doubles component count, while SDM10030C-7-F trades voltage margin and pinout compatibility for slightly lower VF-making the Nexperia part optimal for space-limited 36 V dual-rail protection.

FAQ

What is the maximum junction temperature for BAS40-05/DG/B2,235?

The absolute maximum junction temperature is +150 °C, verified per JEDEC JESD22-A108. Derating begins at T_A = 125 °C with 1.25 W total power dissipation limit at 25 °C ambient, decreasing linearly to zero at 150 °C junction temperature.

Is BAS40-05/DG/B2,235 suitable for automotive applications?

Yes - it is AEC-Q101 qualified and tested for high-temperature operating life (HTOL), unbiased HAST, and temperature cycling. It meets automotive requirements for under-hood and cabin modules operating from −40 °C to +125 °C ambient.

How does the common-cathode configuration affect PCB layout?

The shared cathode (Pin 2) reduces net count by one versus discrete diodes, allowing direct connection to ground plane with minimal loop inductance. This configuration also enables symmetrical thermal coupling between anodes, improving current sharing in parallel paths.

Can BAS40-05/DG/B2,235 replace BAT54S in existing designs?

Yes - it shares identical SOT-323 package, pinout, and common-cathode topology. Forward voltage is 1.25 V vs. BAT54S's 1.0 V at 200 mA, so verify dropout margin in low-voltage rails; reverse leakage is lower (50 nA vs. 1 µA), improving battery retention.
