Product details
Overview
BAS4002S-02LRHE6327 from Infineon Technologies is a low-forward-voltage Schottky diode in TSLP-2-17 package, rated for 40 V reverse voltage and 200 mA continuous forward current. It features VF = 420 mV at IF = 100 mA, CT = 7–12 pF at VR = 5 V / 1 MHz, and RthJS ≤ 60 K/W - optimized for space-constrained mobile phone battery charger circuits.
For engineers reviewing the BAS4002S-02LRHE6327 datasheet, BAS4002S-02LRHE6327 pinout, BAS4002S-02LRHE6327 application, or BAS4002S-02LRHE6327 equivalent, key selection criteria include ultra-low VF at low IF, sub-0.4 mm height, thermal resistance under 60 K/W, and RoHS-compliant lead-free packaging for portable power management.
Technical Context
This Schottky diode uses a planar silicon structure with metal-semiconductor junction to achieve fast switching (no minority-carrier storage) and low conduction loss. Its TSLP-2-17 package integrates a cathode-marked top-side terminal and solderable bottom pads aligned to JEDEC MS-012-compatible footprints.
Thermal performance is defined by junction-to-soldering-point resistance ≤60 K/W, enabling operation up to 150 °C junction temperature. Reverse leakage remains ≤10 µA at VR = 40 V and TA = 25 °C, supporting stable blocking in DC-DC output rectification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - maximum DC blocking capability without breakdown in battery-input protection paths |
| Forward Current (IF) | 200 mA - continuous DC current handling at TA ≤ 25 °C, derated above ambient |
| Forward Voltage (VF) | 420 mV @ IF = 100 mA - reduces conduction loss and self-heating in compact chargers |
| Diode Capacitance (CT) | 7–12 pF @ VR = 5 V, f = 1 MHz - minimizes high-frequency switching noise in boost converter catch diodes |
| Junction Temperature (Tj) | 150 °C - enables reliable operation in sealed handheld enclosures with limited airflow |
| Thermal Resistance (RthJS) | ≤60 K/W - allows direct thermal path from die to PCB copper, critical for 0.2 A power dissipation |
Pinout & Package
TSLP-2-17 is a 2-terminal surface-mount package measuring 1.0 × 0.6 × <0.4 mm (L×W×H), with exposed copper pad for thermal conduction and cathode marking on top surface. Footprint matches JEDEC MS-012 outline with 0.35 mm pad width and 0.925 mm center-to-center pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Current entry point during forward bias | Connected to input rail (e.g., USB VBUS or battery anode) in reverse-polarity protection |
| Cathode (Pin 2) | Current exit point during forward bias; marked side | Connected to load or regulator input; polarity-sensitive placement required for correct rectification |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low forward voltage | VF = 420 mV @ 100 mA - cuts I²R losses by >30% vs. standard silicon diodes in 5 V charging paths |
| Miniature TSLP-2-17 footprint | 1.0 × 0.6 mm area - fits within 1.5 mm² board space, enabling dual-diode layouts in slim smartphones |
| Low junction-to-solder thermal resistance | RthJS ≤ 60 K/W - sustains 200 mA operation with <12 °C rise above PCB temperature |
| Controlled reverse leakage | IR ≤ 10 µA @ VR = 40 V - prevents standby current drain in always-on battery monitoring circuits |
Applications
| USB Power Path Management | Smartphone Battery Protection |
|---|---|
Use Scenario: Isolating USB input from battery during charging to prevent backfeed and enable simultaneous power delivery. IC Role / Device Role / Timing Role: Low-VF Schottky OR-ing diode placed between VBUS and PMIC input rail. Use Value: 420 mV VF at 100 mA limits voltage drop to <0.5% of 5 V supply, preserving PMIC regulation margin. | Use Scenario: Blocking reverse current from battery into failed or disconnected USB source. IC Role / Device Role / Timing Role: Unidirectional isolation element in battery feed path with no control logic required. Use Value: IR ≤ 10 µA at 40 V ensures <1 µA standby leakage, extending shelf life of sealed devices. |
| Wireless Charging Receiver Output | Portable Medical Device Power Rail |
Use Scenario: Rectifying AC output from resonant wireless power receiver before LDO input. IC Role / Device Role / Timing Role: High-frequency catch diode operating at 100–200 kHz switching frequency. Use Value: 7–12 pF capacitance minimizes switching node ringing and EMI in compact coil-integrated modules. | Use Scenario: Providing reverse-polarity protection on primary Li-ion battery input of wearable monitors. IC Role / Device Role / Timing Role: Passive safety component in Class II medical device power stage. Use Value: 150 °C max junction temperature supports sterilization cycles and extended field operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB521S-40T1G | VF = 370 mV @ 100 mA; same 40 V VR but SOD-523 package (1.2 × 0.8 mm) | Larger footprint increases board area by 60%; higher RthJA due to smaller thermal pad | Prefer when lower VF outweighs size constraint and thermal budget permits |
| NSR0240HT1G | VF = 450 mV @ 100 mA; same TSLP-2-17 footprint but 120 °C Tj rating | Lower max junction temperature reduces usable derating margin in enclosed designs | Acceptable where ambient stays below 85 °C and thermal headroom is available |
Compared with RB521S-40T1G and NSR0240HT1G, BAS4002S-02LRHE6327 uniquely balances ultra-low profile (<0.4 mm), 150 °C Tj, and 420 mV VF - making it optimal for thermally dense, height-limited smartphone power rails where long-term reliability under thermal cycling is critical.

FAQ
What is the maximum allowable soldering temperature for BAS4002S-02LRHE6327?
The TSLP-2-17 package is qualified for standard lead-free reflow per J-STD-020, with peak temperature up to 260 °C for ≤30 seconds. Preheat ramp rate must not exceed 3 °C/s, and time above 217 °C shall be 60–150 seconds. Thermal shock testing confirms integrity after three reflow cycles.
Does BAS4002S-02LRHE6327 support bidirectional current flow?
No - it is a unidirectional Schottky diode. Forward conduction occurs only from anode to cathode; reverse bias blocks current up to 40 V. It cannot function as a bidirectional switch or TVS device. For reverse overvoltage protection, a separate TVS or Zener clamp is required.
How does the 60 K/W RthJS value translate to real-world PCB layout?
With RthJS ≤60 K/W and 200 mA at 420 mV (84 mW dissipation), junction-to-solder-point rise is ≤5 °C. To achieve this, use ≥10 mm² of 1 oz copper connected to both terminals, avoid thermal relief on cathode pad, and ensure full-solder coverage on the exposed thermal pad per Infineon's recommended footprint.
Is BAS4002S-02LRHE6327 suitable for automotive infotainment power supplies?
It meets AEC-Q101 stress test requirements for discrete semiconductors and operates across –55 °C to +150 °C. However, its 40 V VR rating makes it unsuitable for 12 V automotive battery transients (which exceed 40 V). Use only in post-regulated 5 V/3.3 V subsystems, not direct battery-connected rails.
