Product details
Overview
BAS12504WE6327HTSA1 from Infineon Technologies is a silicon Schottky diode in SOT323 package configured as a series-connected dual diode, rated for 25 V reverse voltage, 100 mA forward current, and 250 mW power dissipation at TS ≤ 84°C, used for low-loss clamping and bias isolation in automotive metering circuits.
For engineers reviewing the BAS12504WE6327HTSA1 datasheet, BAS12504WE6327HTSA1 pinout, BAS12504WE6327HTSA1 application, or BAS12504WE6327HTSA1 equivalent, key selection criteria include VF matching (≤20 mV at 10 mA), low CT (1.1 pF at 0 V), AEC-Q101 qualification, and thermal resistance RthJS ≤ 365 K/W.
Technical Context
This dual-diode device integrates a diffused guard ring to enhance reverse leakage stability and supports fast-recovery operation with typical VF of 530 mV at 10 mA and differential forward resistance of 15 Ω at 5 mA/10 kHz. Its series configuration enables precise voltage stacking in bias networks.
Designed for automotive-grade reliability, it meets AEC-Q101 stress testing requirements and features Pb-free RoHS-compliant packaging. Reverse current remains ≤100 nA at VR = 20 V and ≤150 nA at VR = 25 V, ensuring low standby power loss in protection circuits.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode pair applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAS12505WE6327HTSA1 | Common-anode dual configuration; same VF/CT but different pin mapping and thermal rating (TS ≤ 76°C) | Used where shared cathode simplifies layout in parallel-bias topologies | Select when circuit requires common-cathode vs. series connection |
| NSR20F30NXT5G | Single Schottky diode (SOD-923); VF = 410 mV @ 10 mA, CT = 1.0 pF, no VF matching spec | Lacks dual-diode integration; requires two devices for series function | Choose only if discrete placement and lower cost outweigh matching and space benefits |
Compared with BAS12504WE6327HTSA1, BAS12505WE6327HTSA1 offers identical electrical specs but alternate topology for different bias schemes, while NSR20F30NXT5G trades integration and matching for lower unit cost and smaller single-diode footprint.

FAQ
What is the pin configuration of BAS12504WE6327HTSA1?
It uses a 3-pin SOT323 package with Pin 1 as anode of Diode 1, Pin 2 as internal cathode/anode junction (not accessible), and Pin 3 as cathode of Diode 2 - forming a monolithic series-connected dual diode. This differs from common-anode or common-cathode variants in the same family.
Is BAS12504WE6327HTSA1 suitable for 125°C ambient operation?
No - its maximum junction temperature is 150°C, but power derating begins at TS > 84°C per datasheet limits. At 125°C ambient, thermal design must ensure junction temperature stays within rating using RthJS ≤ 365 K/W and appropriate copper area, limiting usable IF to ~35 mA continuous.
How does the diffused guard ring improve performance?
The integrated diffused guard ring reduces electric field crowding at the diode periphery, suppressing surface leakage currents and improving long-term stability of IR under high reverse bias and elevated temperature - critical for automotive metering accuracy over 15-year service life.
Can BAS12504WE6327HTSA1 replace a single Schottky diode in clamping circuits?
Only if the circuit explicitly requires two series diodes for voltage stacking or enhanced surge tolerance. Its series configuration yields ~2× VF and ~2× VR capability versus a single diode; substituting it for a single device would introduce unnecessary forward drop and incorrect terminal connectivity.
