Product details
Overview
BAS12507WE6327HTSA1 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, with typical forward voltage of 650 mV at 10 mA - used in low-loss clamping and bias isolation circuits in automotive metering and sensor signal conditioning.
For engineers reviewing the BAS12507WE6327HTSA1 datasheet, BAS12507WE6327HTSA1 pinout, BAS12507WE6327HTSA1 application, or BAS12507WE6327HTSA1 equivalent, key selection criteria include VF matching (≤20 mV), low CT (1.1 pF @ 0 V), differential forward resistance (15 Ω @ 5 mA), AEC-Q101 qualification, and RoHS-compliant SOT343 packaging.
Technical Context
This dual-diode configuration operates as a parallel pair to increase current handling while maintaining matched forward characteristics - critical for precision bias networks and symmetrical clamping paths. Its 1.6 nH series inductance and 1.1 pF capacitance at 0 V/1 MHz support high-frequency transient suppression up to ~300 MHz.
The device features an integrated diffused guard ring for improved voltage standoff stability and ESD robustness (ESD-sensitive handling required). Thermal resistance RthJS ≤ 215 K/W enables reliable operation at junction temperatures up to 150°C under controlled board-level thermal management.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Reverse Voltage) | 25 V - supports rail-to-rail clamping in 24 V automotive sensor interfaces without breakdown |
| IF (Forward Current) | 100 mA DC - sufficient for biasing op-amp input protection networks or LED driver feedback paths |
| VF @ 10 mA | 650 mV typ. - minimizes conduction loss in low-voltage analog front-ends |
| ∆VF @ 10 mA | ≤20 mV - ensures matched conduction across parallel diodes in differential signal paths |
| CT @ 0 V, 1 MHz | 1.1 pF - preserves signal integrity in >100 MHz RF detector or fast-switching clamp applications |
| RthJS | ≤215 K/W - allows direct thermal coupling to PCB copper for sustained 100 mA operation at TS ≤ 96°C |
| IR @ 25 V | 150 nA max. - prevents leakage-induced offset drift in high-impedance bias nodes |
Pinout & Package
SOT343 package: 4-pin plastic surface-mount package with gull-wing leads, 1.3 mm × 1.1 mm footprint, 0.95 mm height, and moisture sensitivity level 1 (MSL1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode 1 | Primary anode connection for first diode element in parallel pair |
| 2 | Cathode | Shared cathode node - internal connection point for both diodes |
| 3 | Anode 2 | Second anode connection enabling true parallel conduction path |
| 4 | No Connect | Internally unconnected; electrically isolated per datasheet marking layout |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood applications including temperature cycling, humidity, and mechanical shock |
| Low VF matching (∆VF ≤ 20 mV) | Enables balanced current sharing in parallel configurations without external trimming resistors |
| Integrated diffused guard ring | Improves edge termination reliability and reduces field crowding at high VR stress |
| Pb-free, RoHS-compliant | Meets EU Directive 2011/65/EU and supports lead-free reflow soldering profiles (JEDEC J-STD-020) |
Applications
| Automotive Instrument Cluster Protection | Industrial Sensor Signal Clamping |
|---|---|
Use Scenario: Protects analog inputs of microcontroller-based gauges from load-dump transients and ESD events in 12 V vehicle systems. IC Role / Device Role / Timing Role: Dual Schottky clamp limiting voltage excursions to ≤0.7 V above rail and ≤0.7 V below ground. Use Value: Prevents latch-up in 3.3 V ADC front-ends while maintaining <1.1 pF loading on 100 kHz sensor signals. | Use Scenario: Shields precision op-amp inputs in 4–20 mA loop receivers from field-wiring surge and polarity reversal. IC Role / Device Role / Timing Role: Parallel-pair diode providing bidirectional rail-to-rail clamping with matched VF for symmetric clipping. Use Value: Delivers ≤20 mV VF mismatch to avoid common-mode error in differential input stages during overvoltage events. |
| Portable Medical Device Bias Isolation | High-Frequency RF Detector Clamp |
Use Scenario: Isolates bias voltage for photodiode transimpedance amplifiers in battery-powered pulse oximeters. IC Role / Device Role / Timing Role: Low-leakage (150 nA max.) Schottky barrier preventing dark-current injection into high-Z nodes. Use Value: Maintains sub-100 nA input bias current integrity while supporting 25 V isolation margin against ESD pulses. | Use Scenario: Front-end clamp in 2.4 GHz ISM-band RF power detectors to limit envelope detector diode swing. IC Role / Device Role / Timing Role: Ultra-low-capacitance (1.1 pF) parallel diode preserving detector bandwidth beyond 300 MHz. Use Value: Enables accurate peak detection without degrading rise time due to parasitic capacitance loading. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode clamp and bias isolation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB050M-30TR | Single diode, SOD-323, 30 V VR, 500 mA IF, VF = 550 mV @ 100 mA | Lacks VF matching and parallel configuration; higher IF but no dual-element symmetry | Preferred where higher surge current matters more than matched clamping |
| NSR0230P2T5G | Single diode, SOD-523, 30 V VR, 200 mA IF, VF = 450 mV @ 10 mA, CT = 1.5 pF | Smaller package, lower VF, but no dual-element structure or AEC-Q101 rating | Used in space-constrained consumer electronics where automotive qualification is not required |
Compared with BAS12507WE6327HTSA1, RB050M-30TR offers higher surge tolerance but lacks matched dual-diode architecture, while NSR0230P2T5G provides lower VF and smaller footprint but omits AEC-Q101 validation and VF matching - making BAS12507WE6327HTSA1 uniquely suited for automotive-grade symmetrical clamping.

FAQ
What is the maximum allowable junction temperature for BAS12507WE6327HTSA1?
The absolute maximum junction temperature is 150°C, as specified in the Infineon datasheet. Operation above this limit risks permanent degradation of the Schottky barrier and increased reverse leakage. Derating curves show that continuous 100 mA operation requires heatsinking to maintain TS ≤ 96°C.
Is BAS12507WE6327HTSA1 pin-compatible with other BAS125 variants?
No - BAS12507WE6327HTSA1 uses SOT343 with a 4-pin parallel-pair configuration, whereas BAS125-04W/05W/06W use SOT323 with series common-cathode or common-anode arrangements. Pin count, footprint, and internal topology differ; direct substitution is not supported.
Does this part require special handling due to ESD sensitivity?
Yes - the datasheet explicitly states it is an ESD-sensitive device. Handling requires grounded wrist straps, conductive foam storage, and ionized air workstations. The device has no on-chip ESD protection; its thin Schottky junction is vulnerable to <2 kV HBM discharge without precautions.
Can BAS12507WE6327HTSA1 be used in AC signal rectification?
No - it is optimized for clamping, bias isolation, and transient suppression, not rectification. Its 100 mA DC rating and lack of specified reverse recovery time (trr) or soft-recovery behavior make it unsuitable for line-frequency or switching-power rectifier applications where charge storage and reverse recovery losses matter.
