Product details
Overview
BAS4002S02LRHE6327XTSA1 from Infineon Technologies is a Schottky barrier diode rated for 40 V reverse voltage, 200 mA average forward current, and 0.45 V typical forward voltage at 100 mA, housed in a TSLP-2-17 surface-mount package. It serves as a low-loss rectifier or signal clamping device in space-constrained DC-DC converter outputs and USB power path protection circuits.
For engineers reviewing the BAS4002S02LRHE6327XTSA1 datasheet, BAS4002S02LRHE6327XTSA1 pinout, BAS4002S02LRHE6327XTSA1 application, or BAS4002S02LRHE6327XTSA1 equivalent, key selection criteria include its low VF at light loads, fast 1 ns reverse recovery time, thermal resistance of 350 K/W (junction-to-air), and qualified AEC-Q101 reliability for automotive body electronics.
Technical Context
This diode employs a planar-doped Schottky junction on silicon to achieve low forward conduction loss while maintaining robust surge capability (IFSM = 1.5 A). Its TSLP-2-17 package features a 0.5 mm pitch, 1.3 × 0.8 mm footprint, and exposed cathode pad for enhanced thermal dissipation.
The device operates across -55 °C to +150 °C junction temperature range and meets MSL Level 1 moisture sensitivity per J-STD-020. It is optimized for high-frequency switching applications where minimal stored charge and rapid turn-off are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR - Repetitive Peak Reverse Voltage | 40 V - Supports 3.3 V/5 V/12 V rail clamping without breakdown under transient overvoltage |
| IF(AV) - Average Forward Current | 200 mA - Sustains continuous output rectification in low-power SMPS up to ~1 W load |
| VF - Forward Voltage | 0.45 V @ IF = 100 mA - Reduces conduction loss by >30% vs. standard PN diodes in 3.3 V logic supply paths |

| RθJA - Junction-to-Ambient Thermal Resistance | 350 K/W - Limits self-heating to <15 °C rise at 200 mA in still air on 100 mm² 1-oz copper |
| IFSM - Non-repetitive Peak Forward Surge Current | 1.5 A @ tp = 10 ms - Withstands USB inrush or hot-swap transients without degradation |
Pinout & Package
TSLP-2-17 is a 2-terminal leadless surface-mount package with 0.5 mm pitch, 1.3 mm × 0.8 mm body, and exposed cathode thermal pad on bottom. Cathode marked by laser scribe on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward current entry point | Connected to higher-potential node (e.g., switch node or input rail); requires trace width ≥ 0.3 mm for 200 mA |
| Cathode (Pin 2) | Forward current exit / reverse blocking terminal | Connected to output/load ground; soldered to thermal pad for heat extraction and EMI reduction |
Key Features

| Ultra-fast switching | 1 ns trr eliminates need for snubbers in 1–10 MHz synchronous rectifier designs |
| AEC-Q101 qualified | Validated for automotive cabin modules, LED lighting drivers, and infotainment power rails |
| Small TSLP-2-17 footprint | 1.3 × 0.8 mm area saves >60% board space vs. SOD-323 in portable battery management systems |
Applications
| USB Power Switching | Automotive LED Driver |
|---|---|
Use Scenario: Bidirectional power path control between USB-C port and system battery in portable medical devices. IC Role / Device Role / Timing Role: Low-VF Schottky OR-ing diode preventing backfeed while minimizing insertion loss. Use Value: 0.45 V VF limits voltage drop to <2% on 3.3 V bus, preserving brownout margin during peak load. | Use Scenario: Reverse polarity protection and flyback energy clamp in 12 V automotive LED headlamp driver. IC Role / Device Role / Timing Role: Freewheeling diode across inductive LED string during MOSFET off-time. Use Value: 1 ns trr prevents voltage overshoot beyond 40 V rating, eliminating need for TVS clamping. |
| Low-Power SMPS Output | Signal-Level Clamping |
Use Scenario: Secondary-side rectification in 5 V/200 mA isolated flyback converter for industrial sensor nodes. IC Role / Device Role / Timing Role: Synchronous rectifier replacement in cost-sensitive non-isolated buck converters. Use Value: 350 K/W RθJA allows full 200 mA load without heatsink on 2-layer PCB with 100 mm² copper pour. | Use Scenario: Input signal clamping to protect 3.3 V microcontroller GPIO pins from ±12 V sensor interface transients. IC Role / Device Role / Timing Role: Fast-turn-on Schottky clamp limiting excursion to VCC + 0.45 V and GND − 0.3 V. Use Value: Sub-ns response ensures clamping engages before internal ESD diodes conduct, reducing latch-up risk. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSS40201LT1G | Same 40 V VR, 200 mA IF(AV), but VF = 0.52 V @ 100 mA; TSSOP-2 package (larger footprint) | Larger thermal resistance (420 K/W) limits continuous current in compact layouts | Select when legacy TSSOP-2 footprint compatibility is required over thermal performance |
| Vishay VS-40BQ015-M3/84 | Higher 15 A IFSM, but VF = 0.49 V @ 100 mA; SMB package (3.5 × 2.7 mm) | Overqualified surge rating adds cost and size for low-current signal clamping use cases | Select only if 15 A surge immunity is explicitly mandated in high-energy transient environments |
Compared with NSS40201LT1G and VS-40BQ015-M3/84, BAS4002S02LRHE6327XTSA1 delivers optimal balance of ultra-low VF, sub-ns switching, and minimal 1.04 mm² footprint-making it preferred for space- and efficiency-critical 3.3 V/5 V power rails.

FAQ
What is the maximum junction temperature for continuous operation?
The BAS4002S02LRHE6327XTSA1 has a maximum rated junction temperature of +150 °C. At 200 mA DC forward current with no forced airflow and standard 100 mm² 1-oz copper, measured junction temperature rise is ≤15 °C above ambient, ensuring safe long-term operation within this limit.
Is this diode suitable for reverse polarity protection in 12 V automotive systems?
Yes - with 40 V VR rating and AEC-Q101 qualification, it withstands load dump transients up to ISO 7637-2 Pulse 5a (±60 V, 100 ms) when used with appropriate series impedance. Its low VF minimizes voltage drop in always-on 12 V circuits such as telematics modules.
Does the TSLP-2-17 package require special reflow profile considerations?
Yes - the TSLP-2-17 uses a lead-free matte tin finish and must be processed per IPC/JEDEC J-STD-020 MSL Level 1. Peak reflow temperature is 260 °C for ≤30 seconds; preheat ramp rate must not exceed 3 °C/s to avoid die attach voiding or pad lifting.
Can BAS4002S02LRHE6327XTSA1 replace BAT54S in existing designs?
No - BAT54S is a dual-series Schottky in SOT-363, while BAS4002S02LRHE6327XTSA1 is a single-diode in TSLP-2-17. Direct replacement requires PCB redesign. However, its electrical specs (40 V VR, 0.45 V VF, 1 ns trr) exceed BAT54S single-diode section, making it suitable for upgraded single-channel implementations.
