Product details
Overview
BAS16WE6327 from Infineon Technologies is a silicon switching diode in SOT-323 (SC-70) package, rated for 80 V reverse voltage, 250 mA forward current, and 4 ns reverse recovery time-optimized for high-speed signal routing and logic-level clamping in automotive and industrial control circuits.
For engineers reviewing the BAS16WE6327 datasheet, BAS16WE6327 pinout, BAS16WE6327 application, or BAS16WE6327 equivalent, this device serves as a fast-switching discrete diode with low forward voltage (1.25 V at 150 mA), tight thermal resistance (125 K/W), and AEC-Q101 qualification for under-hood electronics.
Technical Context
This diode operates as a single-anode–cathode junction with unidirectional conduction. Its 4 ns trr and 2 pF CT at 0 V enable clean edge transitions in 10–50 MHz digital signal paths, while the 150 °C Tj rating supports operation in thermally constrained PCB layouts.
The device uses planar epitaxial construction with gold-doped lifetime control to balance switching speed and leakage. Reverse current remains ≤1 µA at 75 V/25 °C and ≤50 µA at 75 V/150 °C, ensuring stable bias integrity across temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 80 V - supports 24 V and 48 V system rail clamping without breakdown |
| Reverse Recovery Time (trr) | 4 ns - enables reliable operation in >25 MHz clock distribution and data line steering |
| Forward Voltage (VF) | 1.25 V at 150 mA - minimizes power loss in series-connected logic interface protection |
| Junction Temperature (Tj) | 150 °C - qualified for under-hood automotive environments per AEC-Q101 |
| Thermal Resistance (RthJS) | 125 K/W - allows 250 mA continuous current with ≤31 °C junction-to-solder-point rise at 25 °C ambient |
| Diode Capacitance (CT) | 2 pF at 0 V - preserves signal integrity in high-impedance analog switch and RF detector nodes |

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 |
|---|---|---|---|
| MMBD160LW | 4 ns trr, 100 V VR, SOT-323, but VF = 1.3 V at 150 mA | Slightly higher forward drop increases power loss in high-duty-cycle switching | Select when higher reverse margin is required and 0.05 V VF penalty is acceptable |
| BAS116,215 | 4 ns trr, 100 V VR, SOT-23, VF = 1.25 V at 150 mA, but not AEC-Q101 qualified | Lacks automotive qualification; thermal resistance 260 K/W limits current handling | Prefer for cost-sensitive industrial designs where AEC-Q101 is not mandated |
Compared with MMBD160LW and BAS116,215, BAS16WE6327 uniquely combines AEC-Q101 qualification, 80 V VR, 125 K/W RthJS, and 1.25 V VF - making it optimal for thermally dense automotive signal conditioning where reliability and thermal headroom are critical.

FAQ
What is the maximum allowable junction temperature for BAS16WE6327?
The absolute maximum junction temperature is 150 °C, validated per AEC-Q101 stress testing. Operation above this limit risks permanent degradation of the gold-doped junction and accelerated IR drift. Derating curves in the datasheet define safe IF vs. TS relationships up to 150 °C ambient.
Is BAS16WE6327 pin-compatible with BAS116 or MMBD160LW?
No - BAS16WE6327 uses SOT-323 (3-pin) with thermal pad, while BAS116 uses SOT-23 (3-pin, no thermal pad) and MMBD160LW uses SOT-323 but with different pin 1/anode orientation. PCB layout and thermal design must be verified independently for each part.
Does BAS16WE6327 support lead-free reflow soldering?
Yes - it is Pb-free and RoHS compliant, qualified for standard lead-free reflow profiles (peak temperature ≤260 °C, 60-second duration). The plastic package meets JEDEC J-STD-020 moisture sensitivity level 1, eliminating bake requirements prior to assembly.
How does the 2 pF diode capacitance affect high-frequency signal integrity?
At 1 MHz, 2 pF presents ~80 kΩ reactance, minimizing loading on 50 Ω transmission lines. In 10–50 MHz digital clocks or analog sensor outputs, this capacitance introduces <0.5° phase shift and avoids measurable rise-time degradation - confirmed by Infineon's EHN00017 test circuit validation.
