Product details
Overview
MCL101A-TR3 from Vishay Semiconductors is a single small-signal Schottky diode in MicroMELF package, rated for 60 V reverse voltage, 410 mV forward voltage at 1 mA, and 200 nA leakage at 50 V. It delivers low capacitance (2 pF), low leakage, and fast switching for signal detection and protection in space-constrained portable power circuits.
For engineers reviewing the MCL101A-TR3 datasheet, MCL101A-TR3 pinout, MCL101A-TR3 application, or MCL101A-TR3 equivalent, key selection criteria include reverse breakdown voltage, forward voltage at low current, junction-to-ambient thermal resistance, diode capacitance, and MicroMELF packaging compatibility with high-frequency PCB layouts.
Technical Context
The MCL101A-TR3 implements a planar Schottky barrier structure with integrated electrostatic discharge protection ring, enabling stable operation up to 125 °C junction temperature. Its 2 pF capacitance at 0 V and 1 MHz supports HF detector and RF sampling applications where minimal signal loading is critical.
Rated for 30 mA continuous forward current and 2 A non-repetitive surge, the device operates within strict thermal limits: RthJA = 320 K/W on a 50 mm × 50 mm × 1.6 mm PCB. The black cathode band and glass-encapsulated MicroMELF construction ensure unambiguous polarity identification and hermetic reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 60 V - Maximum DC blocking capability without breakdown in protection or clamping paths |
| Forward Voltage (VF) | 410 mV at IF = 1 mA - Enables efficient rectification in ultra-low-power battery charging and sensor biasing |
| Leakage Current (IR) | 200 nA at VR = 50 V - Ensures minimal standby power loss in always-on detection circuits |
| Diode Capacitance (CD) | 2 pF at VR = 0 V, f = 1 MHz - Supports >100 MHz HF detection without signal attenuation |
| Junction-to-Ambient Rth | 320 K/W - Requires careful PCB copper area planning for thermal management above 15 mA continuous current |
| Package | MicroMELF - 1.8 mm diameter × 3.6 mm length glass body with black cathode band; compatible with 8 mm tape reflow |
Pinout & Package
MicroMELF package: cylindrical glass body with axial leads; cathode identified by black band. No discrete pins-device has two terminals: anode (unmarked end) and cathode (banded end). Not applicable for PCB footprint pin numbering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal under forward bias | Connected to lower-potential side in rectifier or clamp configurations; requires trace routing clearance per MicroMELF footprint |
| Cathode | Current exit terminal under forward bias | Marked with black band; tied to higher-potential node in protection circuits; polarity-critical for ESD clamp orientation |
Key Features
| Feature | Design Value |
|---|---|
| Integrated ESD protection ring | Prevents gate oxide damage during board handling without external TVS components |
| Low forward voltage (410 mV) | Reduces conduction loss in 1–10 mA signal-path rectifiers for energy harvesting and sensor interfaces |
| 2 pF junction capacitance | Minimizes phase shift and insertion loss in 10–500 MHz detector and mixer front-ends |
| MicroMELF mechanical robustness | Withstands thermal cycling stress in compact DC/DC converters where SOD-323 or SOD-523 packages crack |
Applications
| HF Detector | Small Battery Charger |
|---|---|
Use Scenario: Demodulating AM signals or sampling RF envelope in portable radios and IoT transceivers. IC Role / Device Role / Timing Role: Signal rectifier converting RF AC to baseband DC with minimal distortion.

Equivalent & Alternatives
The following parts are listed as comparable options for similar small-signal Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAT54LT1G | 30 V VR, 0.32 V VF @ 10 mA, SOT-23 package, 12 pF CD | Higher capacitance limits HF use; surface-mount footprint differs from MicroMELF | Select when board space allows SOT-23 and system VR < 30 V |
| BAT54W-7-F | 30 V VR, 0.24 V VF @ 10 mA, SOT-323 package, 10 pF CD | Lower VR and higher CD reduce suitability for 50 V protection or >50 MHz detection | Prefer for cost-sensitive low-voltage logic-level clamping where MicroMELF assembly is unavailable |
Compared with SBAT54LT1G and BAT54W-7-F, the MCL101A-TR3 provides superior 60 V blocking and 2 pF capacitance for high-frequency and high-reliability roles, but requires MicroMELF-compatible reflow and manual handling due to its glass-body form factor.

FAQ
What is the maximum reverse voltage rating for MCL101A-TR3?
The MCL101A-TR3 has a rated reverse voltage (VR) of 60 V, verified per Vishay Document 85627 Rev. 1.7. This value represents the maximum DC voltage the diode can block continuously at 25 °C ambient without entering avalanche breakdown. Exceeding this rating risks irreversible junction damage, especially at elevated temperatures where leakage increases exponentially. Always derate by ≥20 % for reliability in production designs using MCL101A-TR3.
Does MCL101A-TR3 have a specified forward voltage at higher currents?
Yes, the MCL101A-TR3 specifies 1000 mV typical forward voltage at IF = 15 mA, per the Electrical Characteristics table in Vishay's 85627 datasheet. This value reflects increased resistive drop under moderate load and informs thermal design-dissipation exceeds 15 mW at this point, requiring attention to PCB copper area given the 320 K/W RthJA. The MCL101A-TR3 remains suitable for pulsed or intermittent 15 mA loads in compact layouts.
Is MCL101A-TR3 compatible with lead-free reflow soldering?
Yes, the MCL101A-TR3 MicroMELF package is qualified for lead-free reflow per JEDEC J-STD-020. Its glass body withstands peak temperatures up to 260 °C for 10 seconds. Footprint recommendations in the datasheet specify 2.4 mm pad length for reflow and 2.8 mm for wave soldering. Ensure preheat and soak profiles avoid thermal shock-rapid ramp rates may fracture the glass envelope of MCL101A-TR3.
How does the integrated ESD protection ring in MCL101A-TR3 function?
The integrated ESD protection ring in MCL101A-TR3 is a doped semiconductor structure surrounding the active Schottky junction, designed to bleed electrostatic charge before it reaches the sensitive metal-semiconductor interface. It enables the MCL101A-TR3 to pass HBM testing at ±8 kV without external components. This feature is intrinsic to the die layout-not an add-on-and functions automatically during handling or connector mating, preserving long-term reliability of MCL101A-TR3 in field-deployed equipment.
What is the storage temperature range for MCL101A-TR3?
The MCL101A-TR3 has a specified storage temperature range of –65 °C to +150 °C, as documented in the Thermal Characteristics section of Vishay's 85627 datasheet. This wide range supports long-term warehouse storage, automotive under-hood environments, and industrial outdoor enclosures. Unlike operating junction limits, storage conditions do not require power dissipation derating-but condensation control is advised below –40 °C to prevent moisture ingress into the MicroMELF glass seal of MCL101A-TR3.
