Product details
Overview
BAS170WE6327HTSA1 from Infineon Technologies is a silicon Schottky diode in SOD323 package, rated for 70 V reverse voltage and 70 mA forward current, with low 1.5 pF capacitance at 0 V and 34 Ω forward resistance at 10 mA - used for high-speed switching, voltage clamping, and RF signal mixing in compact consumer and industrial electronics.
For engineers reviewing the BAS170WE6327HTSA1 datasheet, BAS170WE6327HTSA1 pinout, BAS170WE6327HTSA1 application, or BAS170WE6327HTSA1 equivalent, key selection criteria include reverse leakage (≤0.1 µA at 50 V), fast recovery time (≤100 ps), thermal resistance (190 K/W junction-to-soldering-point), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This Schottky diode leverages a low-barrier metal-semiconductor junction to achieve sub-720 mV forward voltage at 15 mA and minimal charge carrier lifetime (≤100 ps), enabling operation in high-frequency detector and clamp circuits up to several hundred MHz. Its 1.5 pF capacitance at zero bias supports stable RF impedance matching in small-signal paths.
The device operates across –55 °C to +125 °C ambient and features a maximum junction temperature of 150 °C. Thermal resistance is specified as 190 K/W (junction-to-soldering-point), consistent with its SOD323 package and optimized for surface-mount reflow profiles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 70 V - supports clamping and protection in 48 V and lower DC supply rails |
| Forward Current (IF) | 70 mA continuous - suitable for low-power signal routing and logic-level detection |
| Diode Capacitance (CT) | 1.5 pF at VR = 0 V, f = 1 MHz - enables use in UHF detector/mixer stages without parasitic loading |
| Forward Voltage (VF) | 720 mV max at IF = 15 mA - ensures low conduction loss in battery-powered sensing nodes |
| Reverse Leakage (IR) | 0.1 µA max at VR = 50 V - maintains signal integrity in precision analog front-ends |
| Recovery Time (τrr) | 100 ps max - allows reliable operation in >100 MHz switching and sampling applications |
| Thermal Resistance (RthJS) | 190 K/W - defines power derating slope under PCB soldering-point thermal constraints |
Pinout & Package
Package: SOD323 - ultra-small plastic surface-mount case (1.7 × 1.25 × 0.95 mm), optimized for high-density PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Current entry point under forward bias | Connected to lower-potential node in clamping or rectification path |
| Cathode (K) | Current exit point under forward bias; marked side of package | Connected to reference or higher-potential rail; polarity-critical for ESD protection orientation |
Key Features

| Pb-free / RoHS compliant | Meets EU Directive 2011/65/EU; compatible with lead-free reflow soldering (JEDEC J-STD-020) |
| Low forward resistance | 34 Ω at 10 kHz - minimizes insertion loss in RF signal paths |
| Fast switching capability | 100 ps reverse recovery - supports sampling clocks and pulse shaping above 100 MHz |
| Stable high-temp operation | Rated for continuous operation up to +125 °C ambient - suitable for under-hood or enclosed industrial modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAT54LT1G | Higher VF (800 mV typ. @ 10 mA); same SOT-23 package; 100 V VR rating | Better suited for higher-voltage clamping but less efficient in low-VF signal detection | Select when reverse voltage margin >70 V is required and 80 mV VF penalty is acceptable |
| NSR0230P2T5G | Lower CT (1.2 pF); 30 V VR; 200 mA IF rating; same SOD-323 footprint | Optimized for 2.4 GHz WiFi front-end clamping, not automotive-grade | Prefer for high-frequency RF designs where capacitance <1.3 pF is critical and AEC-Q101 not mandated |
Compared with SBAT54LT1G and NSR0230P2T5G, BAS170WE6327HTSA1 uniquely balances AEC-Q101 qualification, 70 V rating, and 1.5 pF capacitance - making it the only choice for automotive infotainment RF detectors requiring both reliability and UHF performance.

FAQ
Is BAS170WE6327HTSA1 pin-compatible with BAS70-04W?
No. BAS170WE6327HTSA1 uses the SOD323 package with two terminals (anode/cathode), while BAS70-04W is a quad-diode array in SOT323. Their footprints, pin counts, and internal configurations differ fundamentally - direct substitution requires PCB layout revision.
What is the maximum allowable soldering temperature profile for BAS170WE6327HTSA1?
The device complies with JEDEC J-STD-020D for lead-free reflow: peak temperature ≤260 °C for ≤10 seconds, with ramp-up rate ≤3 °C/s and ramp-down rate ≤6 °C/s. Preheat must stay below 150 °C for 60–120 seconds to avoid package delamination.
Does BAS170WE6327HTSA1 support bidirectional ESD protection?
No. It is a unidirectional Schottky diode configured as anode-to-cathode. For bidirectional protection, two devices must be placed in series opposition or a dedicated TVS diode such as ESD5Z5.0T1G should be used instead.
Can BAS170WE6327HTSA1 replace BAT54 in existing designs?
Only with validation. While both are SOD323 Schottky diodes, BAS170W has higher VR (70 V vs. 30 V) and lower CT (1.5 pF vs. ~10 pF), but also higher VF (720 mV vs. ~320 mV at 1 mA). Performance trade-offs in clamping accuracy and RF bandwidth require circuit-level verification.
