Product details
Overview
BAS12504WH6327XTSA1 from Infineon Technologies is a silicon Schottky diode in SOT323 package configured as a common-cathode dual diode pair, rated for 25 V reverse voltage, 100 mA forward current, and 250 mW total power dissipation at TS ≤ 84°C, used for low-loss clamping and bias isolation in automotive metering circuits.
For engineers reviewing the BAS12504WH6327XTSA1 datasheet, BAS12504WH6327XTSA1 pinout, BAS12504WH6327XTSA1 application, or BAS12504WH6327XTSA1 equivalent, key selection criteria include VF matching (≤20 mV at IF = 10 mA), low CT (1.1 pF at VR = 0 V, f = 1 MHz), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This dual Schottky diode integrates a diffused guard ring to suppress edge leakage and supports fast-recovery operation with low differential forward resistance (15 Ω at IF = 5 mA, f = 10 kHz) and minimal reverse recovery charge. Its common-cathode configuration enables symmetrical clamping across two signal paths while sharing thermal and layout constraints.
Designed for automotive applications, it meets AEC-Q101 stress testing requirements and features Pb-free RoHS-compliant packaging. The device exhibits tight forward voltage matching (ΔVF ≤ 20 mV) across its dual elements-critical for balanced current sharing in bias networks and precision protection circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 25 V - sets maximum allowable blocking voltage before breakdown in clamping or isolation roles |
| Forward Current (IF) | 100 mA - continuous DC current rating per diode element under thermal limits |
| Forward Voltage (VF) | 530 mV typ. @ IF = 10 mA - ensures low conduction loss in low-voltage bias and meter protection |
| Diode Capacitance (CT) | 1.1 pF @ VR = 0 V, f = 1 MHz - minimizes signal distortion in high-frequency clamping applications |
| Thermal Resistance (RthJS) | ≤365 K/W - defines junction-to-solder-point thermal path efficiency for SOT323 mounting |
| VF Matching (ΔVF) | ≤20 mV @ IF = 10 mA - guarantees matched conduction behavior between dual diodes for balanced circuit operation |
Pinout & Package
SOT323 package: surface-mount, 3-pin plastic case with gull-wing leads; pin 1 and pin 2 are anodes, pin 3 is common cathode; footprint compatible with JEDEC MO-203AA standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Diode 1 | Input node for first clamping or isolation path; connects to protected signal line |
| Pin 2 | Anode of Diode 2 | Input node for second independent clamping path; enables dual-rail protection |
| Pin 3 | Common Cathode | Shared return path to reference rail; simplifies PCB routing and thermal coupling |
Key Features
| Feature | Design Value |
|---|---|
| Common-cathode dual configuration | Enables compact dual-channel clamping without discrete interconnects or shared cathode traces |
| AEC-Q101 qualified | Validated for automotive temperature cycling, humidity, and mechanical shock per JESD22 standards |
| Low forward voltage (VF) | Reduces power loss and self-heating in battery-powered metering and sensor interface circuits |
| Integrated diffused guard ring | Suppresses surface leakage and improves long-term stability under high-humidity conditions |
Applications
| Automotive Instrument Cluster Protection | Low-Voltage Sensor Bias Isolation |
|---|---|
Use Scenario: Protecting analog inputs of digital instrument cluster MCUs from ESD and overvoltage transients during vehicle operation. IC Role / Device Role: Dual Schottky clamp limiting input voltage to safe levels while preserving signal integrity. Use Value: Prevents latch-up and damage using <25 V standoff and sub-1 pF capacitance to avoid signal attenuation. | Use Scenario: Isolating bias voltages for precision temperature or pressure sensors in engine control units. IC Role / Device Role: Common-cathode dual diode providing matched forward drop and thermal tracking for dual-sensor rails.

IC Role / Device Role: Dual-path ESD clamp with common cathode tied to system ground plane. Use Value: Leverages 100 nA max IR at 20 V to prevent DC loading of high-impedance touch sense nodes. |
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 (600 mV typ. @ 10 mA); same SOT323 common-cathode package | Less suitable for ultra-low-loss bias networks due to higher conduction loss | Prefer when cost sensitivity outweighs VF performance in non-precision applications |
| BAT54CW | Non-AEC-Q101; VF = 550 mV typ.; CT = 1.2 pF - slightly higher capacitance | Not qualified for automotive use; acceptable for commercial-grade HMI or metering | Select only for non-automotive designs where AEC-Q101 compliance is not required |
Compared with SBAT54DWY and BAT54CW, BAS12504WH6327XTSA1 delivers tighter VF matching (≤20 mV vs. ≥30 mV), lower CT (1.1 pF), and formal AEC-Q101 qualification-making it the preferred choice for automotive instrument clusters and precision sensor biasing where matched performance and reliability are critical.

FAQ
What is the maximum junction temperature for BAS12504WH6327XTSA1?
The absolute maximum junction temperature is 150°C, validated per AEC-Q101 thermal cycling tests. Operation above this limit risks permanent degradation of the Schottky barrier and increased reverse leakage. Derating curves in the datasheet define safe IF versus TS relationships up to 120°C ambient.
Does BAS12504WH6327XTSA1 support bidirectional ESD protection?
No-it is a unidirectional Schottky diode pair with anodes as inputs and common cathode as output. For bidirectional ESD clamping, external TVS diodes or dedicated ESD arrays must be used; this device provides forward-biased clamping only toward the cathode rail.
How is the marking "14s" decoded on the SOT323 package?
"14s" is the top-side laser marking per Infineon's coding scheme: "14" indicates year-week date code (2014, week 14), and "s" denotes the specific wafer lot and assembly location. Full traceability is maintained through Infineon's lot-level documentation and Aetrix's sourcing records.
Can BAS12504WH6327XTSA1 replace single-diode Schottkys like BAT54 in existing layouts?
Yes, but only if the PCB layout accommodates the SOT323 3-pin footprint and the circuit requires dual-anode/common-cathode topology. Pin 1 and 2 serve as independent anodes; pin 3 is shared cathode-unlike BAT54's single-diode SOT23-3 pinout. Layout revision is required for functional replacement.
