Product details
Overview
BAS4002LE6327XTMA1 from Infineon Technologies is a silicon Schottky diode configured as a dual common-anode pair in SOT-23 package, rated for 40 V reverse voltage, 120 mA forward current, and 250 mW power dissipation, with typical forward voltage of 310 mV at 10 mA - used in high-speed switching and voltage clamping circuits in automotive signal conditioning modules.
For engineers reviewing the BAS4002LE6327XTMA1 datasheet, BAS4002LE6327XTMA1 pinout, BAS4002LE6327XTMA1 application, or BAS4002LE6327XTMA1 equivalent, key selection factors include VF matching (≤20 mV), low CT (3 pF @ 0 V), fast τrr (≤100 ps), thermal resistance (RthJS ≤ 275 K/W), and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
This dual common-anode Schottky diode enables independent anode control with shared cathode connection, supporting parallel-path clamping or dual-channel signal routing. Its low forward voltage and sub-100 ps reverse recovery time minimize conduction loss and switching distortion in high-frequency detector and protection circuits.
The device operates across –55 °C to +150 °C, with junction temperature limited to 150 °C and thermal resistance RthJS ≤ 275 K/W (SOT-23 package). It meets AEC-Q101 stress test requirements for automotive under-hood applications, excluding BAS40-02L variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - supports clamping up to 30 V DC rails without breakdown. |
| Forward Current (IF) | 120 mA continuous - sufficient for signal-level switching and logic-level translation. |
| Forward Voltage (VF) | 310 mV typ. @ 10 mA - reduces power loss and self-heating in compact layouts. |
| Diode Capacitance (CT) | 3 pF @ 0 V, 1 MHz - preserves signal integrity in RF detector and mixer stages. |
| Reverse Recovery Time (τrr) | ≤100 ps - enables operation beyond 100 MHz in high-speed sampling and pulse shaping. |
| Thermal Resistance (RthJS) | ≤275 K/W - allows sustained 120 mA operation at ambient up to +81 °C with proper PCB copper area. |
| Operating Temperature | –55 °C to +150 °C - qualified for engine control unit (ECU) and transmission control environments. |
Pinout & Package
Package: SOT-23 (JEDEC TO-236AB), surface-mount, 3-terminal plastic package with gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (Pin 1) | Input anode of first diode | Accepts positive signal or clamp source; electrically isolated from Anode 2. |
| Cathode (Pin 2) | Shared cathode node | Common return path for both diodes; connects to system ground or reference rail. |
| Anode 2 (Pin 3) | Input anode of second diode | Enables dual independent clamping paths sharing one output node. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including ECU, body control, and ADAS sensor interfaces. |
| Dual common-anode configuration | Reduces component count in dual-rail clamping or redundant signal protection schemes. |
| Low VF matching (ΔVF ≤ 20 mV) | Ensures balanced current sharing and consistent threshold behavior between channels. |
| Pb-free, RoHS-compliant | Meets EU Directive 2011/65/EU and automotive ELV requirements for end-of-life recyclability. |
| ESD-sensitive handling | Requires IEC 61340-5-1 compliant workstations; HBM rating ≥2 kV per diode junction. |
Applications
| Automotive Signal Clamping | RF Detector Circuit |
|---|---|
|
Use Scenario: Protecting CAN transceiver inputs from load-dump-induced overvoltage spikes in 12 V vehicle networks. IC Role / Device Role / Timing Role: Fast clamping diode limiting transient excursions to ≤3.6 V above rail.

Use Scenario: Demodulating 900 MHz ISM-band signals in tire pressure monitoring system (TPMS) receivers. IC Role / Device Role / Timing Role: Zero-bias envelope detector leveraging low CT and sub-0.3 V VF. Use Value: Achieves >–25 dBm sensitivity with <0.5 dB insertion loss due to 3 pF capacitance and 10 Ω RF. |
| Logic-Level Translation | High-Speed Sampling Gate |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode clamping applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAS40-04T1G | Single diode, SOT-23, VF = 370 mV @ 10 mA, CT = 4 pF, not AEC-Q101 qualified. | Lacks dual-anode topology; requires two devices for same function; lower thermal margin (RthJS = 375 K/W). | Use only in non-automotive consumer applications where cost outweighs channel integration and qualification. |
| BAT54C,215 | Dual common-cathode configuration, SOT-23, VF = 320 mV @ 10 mA, CT = 10 pF, AEC-Q101 qualified. | Inverted polarity limits use in anode-referenced clamping; higher capacitance degrades >50 MHz performance. | Select when cathode-common architecture aligns with existing PCB layout and RF bandwidth ≤30 MHz is acceptable. |
Compared with SBAS40-04T1G and BAT54C,215, BAS4002LE6327XTMA1 uniquely combines AEC-Q101 qualification, dual common-anode topology, 3 pF capacitance, and ≤275 K/W thermal resistance - making it optimal for space-constrained, high-frequency automotive clamping where polarity and matching matter.

FAQ
Is BAS4002LE6327XTMA1 AEC-Q101 qualified?
Yes. BAS4002LE6327XTMA1 is explicitly qualified per AEC-Q101 Rev D for stress testing including HTGB, TCT, and ESD. This qualification applies to the SOT-23 packaged BAS40 series (excluding BAS40-02L), confirming suitability for automotive under-hood and chassis applications.
What is the maximum allowable junction temperature?
The absolute maximum junction temperature is 150 °C. At TA = 25 °C, the device sustains 120 mA continuous forward current with TS ≤ 81 °C. Derating curves in the datasheet define safe operating area up to 150 °C junction temperature under pulsed conditions.
Can BAS4002LE6327XTMA1 replace BAT54A in a common-anode circuit?
No. BAT54A is a common-anode dual diode but uses SOT-23-3 with Pin 1 = Cathode, Pin 2 = Anode 1, Pin 3 = Anode 2 - opposite pinout to BAS4002LE6327XTMA1 (Pin 1 = Anode 1, Pin 2 = Cathode, Pin 3 = Anode 2). Direct replacement would cause short-circuit unless board layout is modified.
Does BAS4002LE6327XTMA1 support bidirectional signal routing?
No. As a Schottky diode, it conducts only anode-to-cathode. However, its dual common-anode structure allows two independent unidirectional paths into a shared cathode node - useful for OR-ing, clamping, or detector summing, but not true bidirectional switching.
