Product details
Overview
BAS12507WH6327XTSA1 from Infineon Technologies is a silicon Schottky diode in SOT343 package configured as a parallel pair, rated for 25 V reverse voltage, 100 mA forward current, and 250 mW power dissipation at TS ≤ 96°C, used for low-loss clamping and bias isolation in automotive metering circuits.
For engineers reviewing the BAS12507WH6327XTSA1 datasheet, BAS12507WH6327XTSA1 pinout, BAS12507WH6327XTSA1 application, or BAS12507WH6327XTSA1 equivalent, key selection criteria include VF matching (≤20 mV at 10 mA), low CT (1.1 pF at 0 V), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This dual-diode configuration enables simultaneous signal path protection with matched forward characteristics, supporting precise voltage clamping in analog front-ends where thermal tracking between elements is critical. Its integrated diffused guard ring ensures stable reverse leakage (<150 nA at 25 V) across temperature.
The device operates with low differential forward resistance (15 Ω typ. at 5 mA/10 kHz) and exhibits minimal capacitance variation (0.2–0.8 pF over 0–20 V), making it suitable for high-frequency bias networks and ESD-sensitive measurement inputs.
Key Specifications

|---|---|
| Reverse Voltage (VR) | 25 V - Maximum blocking capability before breakdown in clamping or isolation paths |
| Forward Current (IF) | 100 mA - Continuous DC current handling for bias supply routing |
| Forward Voltage (VF) | 530–650 mV @ 10 mA - Low conduction loss enabling efficient low-voltage signal conditioning |
| Diode Capacitance (CT) | 1.1 pF @ 0 V, 1 MHz - Minimal loading on high-speed analog nodes |
| VF Matching (∆VF) | ≤20 mV @ 10 mA - Ensures balanced current sharing in parallel-pair configurations |
| Junction Temp (Tj) | 150 °C - Supports operation in under-hood automotive environments |
| Thermal Resistance (RthJS) | ≤215 K/W - Enables reliable power dissipation at elevated board temperatures |

Applications
| Automotive Instrument Clamping | Low-Voltage Sensor Biasing |
|---|---|
Use Scenario: Protecting analog inputs of digital vehicle speedometers against transients induced by ignition noise or load dump. IC Role / Device Role / Timing Role: Dual Schottky clamp limiting input swing to ±0.7 V while preserving signal integrity. Use Value: Prevents ADC saturation and latch-up without adding series resistance that degrades resolution. | Use Scenario: Providing matched bias currents to dual-output Hall-effect position sensors in EPS modules.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode pair applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAT54DWY | Higher VF (700 mV typ. @ 10 mA), same SOT343, no AEC-Q101 rating | Not qualified for automotive use; suitable only for industrial/commercial metering | Select when AEC-Q101 compliance is not required and higher VF is acceptable |
| BAT54CW | Single-channel SOT323 variant; no VF matching spec; RthJS = 365 K/W | Limited to single-rail clamping; lower thermal performance restricts continuous IF to 60 mA | Choose only for space-constrained non-automotive designs needing basic dual-anode functionality |
Compared with SBAT54DWY and BAT54CW, BAS12507WH6327XTSA1 delivers tighter VF matching, superior thermal resistance, and automotive qualification-making it the sole option for AEC-Q101-compliant dual-clamp designs requiring <20 mV matching and >80 mA sustained current at 96°C board temperature.

FAQ
What is the maximum allowable junction temperature for BAS12507WH6327XTSA1?
The absolute maximum junction temperature is 150°C, validated per AEC-Q101 stress testing. Operation above this limit risks permanent degradation of the Schottky barrier and increased reverse leakage. Derating curves in the datasheet define safe IF vs. TS limits, with full 100 mA rating permitted only below 96°C case temperature.
Is BAS12507WH6327XTSA1 pin-compatible with BAS125-04W or BAS125-05W?
No-BAS12507WH6327XTSA1 uses SOT343 (4-pin), whereas BAS125-04W and BAS125-05W use SOT323 (3-pin). The pin count, layout, and internal configuration differ: BAS125-04W is common-cathode, BAS125-05W is common-anode, and BAS12507WH6327XTSA1 is parallel-pair with independent anodes and shared cathode/thermal pad.
Does BAS12507WH6327XTSA1 require special PCB layout considerations?
Yes-its SOT343 package includes an exposed thermal pad (Pin 4) that must be soldered to a minimum 25 mm² copper pour with ≥4 thermal vias to internal ground planes. Inadequate thermal relief reduces effective RthJS from 215 K/W to >300 K/W, risking thermal runaway at rated current.
Can BAS12507WH6327XTSA1 be used in AC signal rectification applications?
No-it is optimized for DC bias isolation and transient clamping, not rectification. Its low VR (25 V) and limited IFSM (500 mA) make it unsuitable for line-frequency or switching-power supply rectification. Use dedicated rectifier diodes like BAS21 or BYV26E for such roles.
