Product details
Overview
BAS16WH6327XTSA1 from Infineon Technologies is a silicon high-speed switching diode in SOT-323 (SC-70) package, rated for 80 V reverse voltage, 250 mA forward current, and 4 ns reverse recovery time, used in automotive signal routing, ESD-protected I/O clamping, and low-power logic-level translation circuits.
For engineers reviewing the BAS16WH6327XTSA1 datasheet, BAS16WH6327XTSA1 pinout, BAS16WH6327XTSA1 application, or BAS16WH6327XTSA1 equivalent, key selection criteria include reverse recovery time under 4 ns, thermal resistance ≤250 K/W, AEC-Q101 qualification, and RoHS-compliant lead-free packaging.
Technical Context
This diode operates as a unidirectional, single-anode–cathode junction device optimized for fast transient response in digital interface protection and level-shifting paths. Its 2 pF capacitance at 0 V and 1.25 V forward voltage at 150 mA enable minimal signal distortion in 3.3 V/5 V bus applications.
The device meets AEC-Q101 stress testing requirements for automotive use, with guaranteed operation from –65 °C to +150 °C junction temperature and thermal resistance RthJS ≤ 250 K/W when mounted on standard PCB copper land patterns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 80 V - supports 24 V automotive supply rail clamping with 3× safety margin |
| Reverse Recovery Time (trr) | 4 ns - enables reliable operation in >100 MHz digital signal paths |
| Forward Current (IF) | 250 mA - sustains continuous drive for LED indicators and logic gate inputs |
| Junction Temperature (Tj) | 150 °C - qualified for under-hood automotive environments |
| Diode Capacitance (CT) | 2 pF at 0 V - minimizes loading on high-speed data lines (e.g., UART, SPI) |
| Forward Voltage (VF) | 1.25 V at 150 mA - ensures low power loss in battery-powered sensor interfaces |
| Thermal Resistance (RthJS) | ≤250 K/W - allows direct mounting on 10 mm² 1-oz copper without heatsink |
Pinout & Package
Package: SOT-323 (SC-70), 3-pin surface-mount plastic case with gull-wing leads; moisture sensitivity level (MSL) 1 per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Current entry node | Connected to higher-potential side of signal path for forward conduction |
| Cathode (Pin 2) | Current exit node | Connected to reference or lower-potential rail for clamping and protection |
| Case / Heat Sink (Pin 3) | Thermal path only | Electrically isolated metal tab for thermal dissipation; not connected internally |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements including HTGB, HTRB, and TCT |
| Pb-free (RoHS compliant) | Meets EU Directive 2011/65/EU with no exemption required for lead content |
| Low reverse recovery charge | trr = 4 ns with 10 mA switching conditions reduces EMI in adjacent analog sections |
| High surge tolerance | 4.5 A non-repetitive peak forward surge withstands ESD-induced transients per IEC 61000-4-2 |
| Stable high-temp performance | IR ≤ 50 µA at 150 °C and 75 V reverse bias ensures reliability in engine control units |
Applications

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 |
|---|---|---|---|
| MMBD1619LT1G | 4 ns trr, 100 V VR, SOT-23 package; 30 % larger footprint than SOT-323 | Higher voltage margin but requires PCB redesign for pad layout | Select when system-level surge tests exceed 80 V or board space permits larger package |
| BAS116W,115 | Same SOT-323 package, 100 V VR, 3.5 ns trr; not AEC-Q101 qualified | Lacks automotive qualification; suitable only for industrial/commercial designs | Choose for cost-sensitive non-automotive applications requiring faster recovery |
Compared with MMBD1619LT1G and BAS116W,115, BAS16WH6327XTSA1 uniquely balances AEC-Q101 compliance, SOT-323 compactness, and 4 ns recovery in a single-source automotive-qualified part.

FAQ
Is BAS16WH6327XTSA1 pin-compatible with BAS16W?
Yes - both share identical SOT-323 (SC-70) pinout: Pin 1 = Anode, Pin 2 = Cathode, Pin 3 = Case/thermal pad. The "H6327" suffix denotes tape-and-reel packaging per EIA-481 standard, not functional or pinout variation.
What is the maximum allowable soldering temperature for BAS16WH6327XTSA1?
The device complies with JEDEC J-STD-020D MSL 1, permitting peak reflow temperatures up to 260 °C for 10 seconds. Hand-soldering must not exceed 350 °C for ≤3 seconds per joint to avoid die metallization damage.
Does BAS16WH6327XTSA1 support bidirectional ESD protection?
No - it is a unidirectional diode. For bidirectional clamping, two devices must be connected anode-to-anode or cathode-to-cathode; dedicated TVS arrays like ESD5Z5.0T1G are recommended for integrated dual-rail protection.
Can BAS16WH6327XTSA1 replace BAT54 in 3.3 V logic circuits?
Yes, with verification: both are SOT-323 Schottky-like silicon switching diodes, but BAS16WH6327XTSA1 has higher VR (80 V vs. 30 V) and slower trr (4 ns vs. ~1 ns). Use only where voltage margin matters more than ultra-fast switching.
