Product details
Overview
BAS1602WH6327XTSA1 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. It serves as a fast signal-path switch in automotive body control modules, USB port protection circuits, and low-voltage logic-level clamping applications.
For engineers reviewing the BAS1602WH6327XTSA1 datasheet, BAS1602WH6327XTSA1 pinout, BAS1602WH6327XTSA1 application, or BAS1602WH6327XTSA1 equivalent, key selection criteria include its AEC-Q101 qualification, 2 pF junction capacitance at 0 V, 1.25 V forward voltage at 150 mA, thermal resistance of 250 K/W, and RoHS-compliant leadless packaging.
Technical Context
This diode employs a planar epitaxial silicon structure optimized for minimal charge storage and rapid carrier recombination. Its 4 ns reverse recovery time (trr) is measured under standardized IF = IR = 10 mA conditions with 1 mA sensing threshold and 100 Ω load, enabling reliable operation in 10–50 MHz digital signal routing.
The device exhibits low leakage: IR ≤ 1 µA at VR = 75 V and TA = 25 °C, rising to ≤ 50 µA at 150 °C - critical for thermally demanding engine bay electronics. Its VF vs. IF curve shows 855 mV typ. at 10 mA and 1250 mV max. at 150 mA, supporting stable biasing in low-power interface circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 80 V - supports 24 V automotive supply rail with 3.3× safety margin against transients |
| Reverse Recovery Time (trr) | 4 ns - enables clean switching in >25 MHz clock distribution and data line steering |
| Junction Capacitance (CT) | 2 pF at VR = 0 V, f = 1 MHz - minimizes signal distortion in high-speed GPIO and I²C lines |
| Forward Voltage (VF) | 1250 mV max. at IF = 150 mA - ensures predictable voltage drop in series-clamp configurations |
| Thermal Resistance (RthJS) | 250 K/W - defines maximum power derating slope of −1.0 mW/°C above 85 °C ambient |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD (HBM ≥ 8 kV) |
Pinout & Package
SOT-323 (SC-70) plastic surface-mount package with gull-wing leads; 1.3 mm × 2.1 mm footprint, 0.95 mm height, and moisture sensitivity level 1 (MSL1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Current entry node | Connected to higher-potential side in clamping or steering paths; requires trace width ≥ 0.25 mm for 250 mA DC |
| Cathode (Pin 2) | Current exit node | Typically tied to ground or logic-low reference; forms low-impedance return path during reverse-biased blocking |
| Case / Exposed Pad (Pin 3) | Thermal and electrical ground | Internally connected to cathode; must be soldered to ≥ 25 mm² copper pour for thermal performance |
Key Features
| Feature | Design Value |

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,115 (Nexperia) | Same SOT-323 package, 4 ns trr, but VF = 1.25 V max. at 150 mA; RthJS = 250 K/W; AEC-Q101 qualified | No functional difference; identical pinout and thermal profile; minor VF tolerance variation within spec | Select when dual-sourcing required with identical parametric envelope and qualification status |
| MMBD1204LT1G (ON Semiconductor) | SOT-23 package; 4 ns trr; VF = 1.25 V max. at 150 mA; VR = 80 V; not AEC-Q101 qualified | Requires PCB redesign due to different footprint; suitable for industrial but not automotive applications | Choose for cost-sensitive non-automotive designs where AEC-Q101 is not mandated |
Compared with BAS16W,115, this part offers identical performance and qualification; versus MMBD1204LT1G, it provides guaranteed automotive reliability at the cost of package compatibility - making it the preferred choice for Tier-1 automotive subsystems requiring zero requalification effort.

FAQ
Is BAS1602WH6327XTSA1 pin-compatible with standard BAS16 variants?
Yes - it uses the SOT-323 (SC-70) package with standard anode-cathode-case pinout (Pin 1 = anode, Pin 2 = cathode, Pin 3 = case/cathode). It replaces BAS16W and BAS16S in footprint-constrained layouts without PCB modification.
What is the maximum allowable junction temperature during continuous operation?
The absolute maximum junction temperature is 150 °C. Derating begins at 85 °C ambient: power dissipation must be reduced linearly from 250 mW at 85 °C to 0 mW at 150 °C, per the RthJS = 250 K/W specification.
Does this diode support bidirectional ESD protection?
No - it is a unidirectional switching diode. For bidirectional protection, two devices must be used in series-opposed configuration (anode-to-anode or cathode-to-cathode), as confirmed by Infineon's application note AN2017-07.
Can BAS1602WH6327XTSA1 be used in place of a Schottky diode?
Only in non-ultra-low-VF applications: its 1250 mV VF max. at 150 mA is higher than typical Schottky diodes (<500 mV). It should replace Schottkys only where trr < 4 ns and VR > 60 V are prioritized over forward loss, such as in high-frequency signal routing.
