Product details
Overview
BAT6203WE6327HTSA1 from Infineon Technologies is a Schottky barrier diode rated for 40 V reverse voltage, 100 mW power dissipation, and 100 mA forward current in a SOD323 surface-mount package; it delivers low forward voltage drop (0.35 V at 10 mA) and fast switching for RF detector and mixer applications in wireless transceivers.
For engineers reviewing the BAT6203WE6327HTSA1 datasheet, BAT6203WE6327HTSA1 pinout, BAT6203WE6327HTSA1 application, or BAT6203WE6327HTSA1 equivalent, key selection criteria include junction capacitance (0.35 pF at 0 V), series resistance (22 Ω), reverse recovery time (<1 ns), and thermal resistance (450 K/W).
Technical Context
This Schottky diode employs a planar-doped barrier structure optimized for high-frequency signal detection and mixing. Its low junction capacitance and minimal stored charge enable operation up to 2.5 GHz with stable RF performance across temperature.
The device features a single anode-cathode configuration with no integrated guard ring or ESD protection. It is designed for DC-biased small-signal operation-not for power rectification or surge handling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Max) | 40 V - maximum allowable reverse bias before breakdown in RF detector bias networks |
| IF (Max) | 100 mA - continuous forward current limit defining safe operating area in mixer IF paths |
| VF @ 10 mA | 0.35 V - low conduction loss enabling high sensitivity in zero-bias detector circuits |
| Cj @ 0 V | 0.35 pF - minimal parasitic capacitance preserving impedance matching above 2 GHz |
| RS | 22 Ω - series resistance directly limiting insertion loss in 50 Ω RF signal paths |
| Trr | <1 ns - ultrafast recovery ensuring minimal distortion in pulsed RF envelope detection |
Pinout & Package
Supplied in SOD323 (SC-76) plastic surface-mount package: 1.3 mm × 0.85 mm footprint, 0.9 mm height, gull-wing leads, cathode marked by band.

| Anode (Pin 1) | Forward current entry point | Connected to RF input or local oscillator coupling node in mixer topologies |
| Cathode (Pin 2) | Forward current exit / reverse bias terminal | Bonded to ground or DC bias rail; polarity critical for correct detector polarity |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky detector diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSVRB520CSHT5G | VF = 0.45 V @ 10 mA; Cj = 0.45 pF; SOD-523 package | Higher VF reduces sensitivity in weak-signal detection; smaller package increases assembly challenge | Prefer when board space is constrained and 0.1 V higher VF is acceptable |
| BAT62-03W-E6327 | Identical electrical specs; same SOD323 package; differing tape-and-reel packaging (HTSA1 vs standard) | No functional difference; HTSA1 denotes AEC-Q200 stress-tested variant | Select HTSA1 for automotive-grade reliability; standard version suffices for consumer RF modules |
Compared with NSVRB520CSHT5G, BAT6203WE6327HTSA1 offers superior sensitivity in low-input-power detection; versus BAT62-03W-E6327, it provides verified automotive qualification without trade-offs in RF performance or layout compatibility.

FAQ
Is BAT6203WE6327HTSA1 suitable for zero-bias detector applications?
Yes. With a forward voltage of only 0.35 V at 10 mA and junction capacitance of 0.35 pF, it operates effectively without external bias in RF envelope detection circuits-commonly used in RKE and BLE beacon receivers where power efficiency is critical.
What is the thermal resistance (RthJ-A) of BAT6203WE6327HTSA1?
The junction-to-ambient thermal resistance is 450 K/W under standard SOD323 mounting on FR-4 PCB with 1 cm² copper pad. This value assumes natural convection and defines maximum power derating above 25°C ambient-critical for sustained RF detector operation.
Does BAT6203WE6327HTSA1 have integrated ESD protection?
No. BAT6203WE6327HTSA1 is a bare Schottky junction diode without on-chip ESD structures. System-level ESD protection (e.g., external TVS or RC filters) must be implemented upstream in RF signal paths per IEC 61000-4-2 Level 2 requirements.
Can BAT6203WE6327HTSA1 replace BAT54 in RF detector circuits?
No. BAT54 has higher VF (0.8 V), larger Cj (10 pF), and slower recovery (>5 ns), making it unsuitable for >1 GHz detection. BAT6203WE6327HTSA1's 0.35 pF and <1 ns recovery provide measurable SNR and bandwidth advantages above 800 MHz.
