Product details
Overview
BAS1603WE6327HTSA1 from Infineon Technologies is a silicon high-speed switching diode in SOD-323 (SCD80) package, rated for 80 V reverse voltage, 250 mA forward current, and 4 ns reverse recovery time, used in automotive signal routing and low-power logic clamping circuits.
For engineers reviewing the BAS1603WE6327HTSA1 datasheet, BAS1603WE6327HTSA1 pinout, BAS1603WE6327HTSA1 application, or BAS1603WE6327HTSA1 equivalent, key selection criteria include reverse recovery time, junction temperature limit, thermal resistance, AEC-Q101 qualification, and SOD-323 footprint compatibility with space-constrained PCB layouts.
Technical Context
This diode operates as a unidirectional fast-switching element with low forward voltage drop (1.25 V at 150 mA) and minimal junction capacitance (2 pF at 0 V), enabling clean edge transitions in digital signal conditioning paths.
Its AEC-Q101 qualification confirms suitability for automotive environments, and its 150 °C maximum junction temperature supports operation in under-hood electronics where ambient temperatures exceed 125 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 80 V - supports 24 V automotive supply rail transient suppression without breakdown |
| Reverse Recovery Time (trr) | 4 ns - enables reliable switching at >100 MHz clock rates in data line protection |
| Forward Current (IF) | 250 mA - sufficient for driving small-signal logic inputs or LED indicators |
| Junction Temperature (Tj) | 150 °C - allows deployment in engine control units and powertrain modules |
| Thermal Resistance (RthJS) | 250 K/W - defines heat dissipation capability when mounted on standard FR-4 with minimal copper area |
| Capacitance (CT) | 2 pF at 0 V - minimizes signal loading on high-speed I/O lines such as CAN or LIN stubs |
Pinout & Package
Package: SOD-323 (SCD80), surface-mount, 2-terminal plastic case with cathode band marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to lower-potential node (e.g., MCU I/O pin or ground-referenced signal source) |
| Cathode | Current exit point during forward conduction; marked with band | Connected to higher-potential node (e.g., 3.3 V/5 V rail or pull-up resistor) |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22-A114 |
| Low trr = 4 ns | Reduces switching loss and prevents false triggering in high-frequency enable/disable control signals |
| Pb-free RoHS-compliant | Meets EU Directive 2011/65/EU and IPC-J-STD-020 moisture sensitivity level 1 (MSL1) |
| VF = 1.25 V @ 150 mA | Minimizes voltage drop in series-connected logic-level translation or clamp paths |
Applications
| Automotive Signal Clamping | Logic-Level Translation |
|---|---|
Use Scenario: Protecting LIN bus transceiver inputs from ESD and load-dump transients in body control modules. IC Role / Device Role: Unidirectional transient voltage clamp placed between I/O pin and VCC rail. Use Value: 4 ns trr ensures no signal distortion during 20 kbps LIN frame transmission while limiting overshoot to <12 V. | Use Scenario: Level-shifting 1.8 V GPIO outputs to interface with 3.3 V sensor peripherals in ADAS domain controllers. IC Role / Device Role: Passive forward-biased diode in series with pull-up to define threshold voltage offset. Use Value: 1.25 V VF at 150 mA provides predictable 1.05 V shift, enabling robust low-voltage logic recognition. |

Use Value: 250 mA IF rating supports dual-rail 100 mA loads; 80 V VR margin accommodates 12 V system surges. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAS16W,215 (Nexperia) | Same SOD-323 package, 4 ns trr, but VF = 1.25 V @ 100 mA (vs. 1.25 V @ 150 mA for BAS1603WE6327HTSA1) | Identical use in clamping and OR-ing; slightly lower IF rating (200 mA vs. 250 mA) | Select when sourcing flexibility is prioritized and peak current remains ≤200 mA |
| MMBD1204LT1G (ON Semiconductor) | SOT-23 package, 4 ns trr, VF = 1.1 V @ 100 mA, but not AEC-Q101 qualified | Not suitable for automotive under-hood applications; acceptable for industrial control panels | Choose only for non-automotive designs where AEC-Q101 compliance is not required |
Compared with BAS16W,215, BAS1603WE6327HTSA1 offers higher forward current capability and identical AEC-Q101 validation; versus MMBD1204LT1G, it trades SOT-23 availability for guaranteed automotive qualification and tighter thermal performance in SOD-323.

FAQ
Is BAS1603WE6327HTSA1 pin-compatible with other BAS16 variants?
No - BAS1603WE6327HTSA1 uses the SOD-323 (SCD80) package, whereas BAS16-02L and BAS16-07L4 use TSLP-2-1 and TSLP-4-4 packages respectively. Pin count and pad layout differ across variants; mechanical and thermal footprints are not interchangeable without PCB redesign.
What is the maximum allowable soldering temperature for BAS1603WE6327HTSA1?
The device complies with IPC-J-STD-020 MSL1, permitting peak reflow temperature up to 260 °C for 30 seconds. Hand-soldering must not exceed 350 °C for more than 3 seconds per terminal to avoid die attach degradation or molding compound delamination.
Does BAS1603WE6327HTSA1 support bidirectional ESD protection?
No - it is a unidirectional silicon switching diode. For bidirectional ESD protection, a dedicated TVS array (e.g., ESD5V3U1U) or back-to-back diode configuration is required; this part conducts only anode-to-cathode and blocks in reverse bias.
Can BAS1603WE6327HTSA1 be used in place of a Schottky diode?
Only in non-critical low-VF applications - its 1.25 V forward voltage at 150 mA is higher than typical Schottky diodes (0.3–0.5 V). It should not replace Schottky rectifiers in power conversion, but is suitable where speed and ruggedness outweigh VF concerns, such as signal clamping.
