Product details

Overview

BAT1705E6327HTSA1 from Infineon Technologies is a Schottky barrier diode rated for 4 V reverse voltage, 150 mW power dissipation, and 100 mA forward current in SOT23-3 package; used for low-loss signal clamping and high-speed switching in portable DC-DC converters.

For engineers reviewing the BAT1705E6327HTSA1 datasheet, BAT1705E6327HTSA1 pinout, BAT1705E6327HTSA1 application, or BAT1705E6327HTSA1 equivalent, key selection criteria include low forward voltage (0.35 V at 10 mA), fast recovery time (≤1 ns), low junction capacitance (0.4 pF at 0 V), and thermal resistance (450 K/W).

Technical Context

This Schottky diode employs a platinum-silicide (PtSi) anode on silicon to achieve low forward voltage and minimal stored charge. Its structure enables operation up to 1 GHz with negligible minority-carrier storage delay.

The device is optimized for RF detector and mixer applications where low barrier height and ultra-low capacitance are critical. It supports continuous forward current up to 100 mA with derating above 25 °C ambient.

Key Specifications

Parameter	Value and Actual Design Meaning
V_R (Max)	4 V - Maximum reverse blocking voltage before breakdown; defines safe operating range in clamp or ESD protection circuits.
I_F (Max)	100 mA - Continuous forward current rating; determines usable current headroom in signal routing paths.
V_F @ 10 mA	0.35 V - Low forward drop minimizes power loss and voltage offset in precision detector or biasing networks.
C_j @ 0 V	0.4 pF - Ultra-low junction capacitance preserves high-frequency signal integrity in RF front-end stages.
t_rr	≤1 ns - Fast recovery enables use in >500 MHz switching and pulse detection without tail current distortion.
P_tot	150 mW - Total power dissipation limit at T_A = 25 °C; sets thermal design boundary for PCB layout and trace width.

Pinout & Package

SOT23-3 package: plastic surface-mount case with gull-wing leads, 1.3 mm × 2.9 mm footprint, 1.1 mm height, and standard JEDEC MO-178 alignment.

Pin/Terminal	Circuit Role	Design Meaning
1 (Anode)	Anode connection	Forward current entry point; connects to higher-potential node in clamping or rectification path.
2 (Cathode)	Cathode connection	Forward current exit point; typically tied to ground or reference rail in detector configurations.
3 (Cathode)	Cathode connection	Second cathode terminal for improved thermal and current sharing; electrically common with Pin 2.

Key Features

Feature	Design Value
Low forward voltage	0.35 V at 10 mA - Reduces insertion loss and improves sensitivity in RF detector circuits.
Ultra-low capacitance	0.4 pF at 0 V - Enables operation beyond 1 GHz without resonant degradation in matching networks.
Fast switching speed	≤1 ns recovery - Supports pulse edge fidelity in time-domain sampling and envelope detection.
Thermally robust package	SOT23-3 with dual cathode terminals - Enhances heat spreading and current handling versus single-cathode variants.

Applications

RF Detector Circuit

ESD Protection Node

Use Scenario: Detecting RF envelope in 868 MHz ISM-band receiver front-ends.

IC Role / Device Role / Timing Role: Signal-level rectifier converting RF amplitude to DC baseband voltage.

Use Value: 0.4 pF capacitance avoids detuning of 50 Ω input matching; 0.35 V V_F preserves dynamic range below –20 dBm.

Use Scenario: Protecting GPIO pins of ultra-low-power microcontrollers against IEC 61000-4-2 contact discharge.

IC Role / Device Role / Timing Role: Fast-turn-on shunt clamp diverting transient current away from sensitive inputs.

Use Value: ≤1 ns t_rr ensures clamping activation before 300 ps rise-time transients propagate into core logic.

High-Speed Logic Clamp

DC-DC Converter Feedback Path

Use Scenario: Limiting overshoot on LVDS or USB 2.0 data lines during hot-plug events.

IC Role / Device Role / Timing Role: Bidirectional voltage limiter referenced to V_CC and GND rails.

Use Value: Dual cathode (Pins 2 & 3) lowers effective series inductance, improving sub-nanosecond response to fast edges.

Use Scenario: Isolating feedback resistor divider from output ripple in 3 MHz synchronous buck converters.

IC Role / Device Role / Timing Role: Reverse-biased blocking diode preventing capacitor discharge through feedback network.

Use Value: 4 V V_R provides 2× margin over typical 1.8 V feedback node voltage; 150 mW rating handles worst-case leakage power.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
NSR0230HT1G	Higher V_R (30 V), higher C_j (1.5 pF), same SOT23-3 package.	Less suitable for >500 MHz RF detection due to capacitance; better for general-purpose clamping.	Select when reverse voltage margin >10× required and frequency <100 MHz.
BAT54C,215	Higher V_F (0.5 V at 10 mA), dual-diode configuration, same package.	Not single-diode; requires redesign for unidirectional signal paths.	Choose only if dual-cathode topology matches existing layout and 0.5 V V_F is acceptable.

Compared with NSR0230HT1G and BAT54C,215, BAT1705E6327HTSA1 offers superior RF performance due to its 0.4 pF capacitance and 0.35 V forward drop-critical for sub-1 GHz detector sensitivity and low-voltage bias stability.

FAQ

What is the maximum reverse voltage rating for BAT1705E6327HTSA1?

The BAT1705E6327HTSA1 has a maximum repetitive peak reverse voltage (V_RRM) of 4 V. This rating is specified under pulsed conditions with T_j ≤ 150 °C and defines the absolute upper limit for safe reverse-bias operation without avalanche conduction or permanent degradation.

Can BAT1705E6327HTSA1 be used in 2.4 GHz Wi-Fi front-ends?

No-its 0.4 pF junction capacitance and PtSi process yield optimal performance up to ~1 GHz. At 2.4 GHz, parasitic reactance dominates, causing mismatch and insertion loss exceeding 3 dB; dedicated GaAs or SiGe Schottky diodes are recommended for 2.4 GHz detector applications.

Is BAT1705E6327HTSA1 RoHS compliant and halogen-free?

Yes-BAT1705E6327HTSA1 complies with RoHS Directive 2011/65/EU and is certified halogen-free per IEC 61249-2-21. The "HTSA1" suffix denotes tape-and-reel packaging with lead-free termination finish (SnAgCu) and full material declaration per IPC-1752A.

How does the dual-cathode configuration (Pins 2 and 3) affect PCB layout?

The dual cathode terminals reduce effective bond wire inductance and improve thermal spreading. Layout best practice is to connect both Pins 2 and 3 directly to the same low-impedance ground plane using separate short traces-avoid daisy-chaining or shared vias to preserve sub-nanosecond switching fidelity.
