Product details
Overview
CMS14(TE12L,Q,M) from Toshiba is a surface-mount Schottky barrier diode optimized for high-frequency rectification in DC-DC converters and switching regulators. It delivers 2.0 A average forward current, 60 V repetitive peak reverse voltage, and a low 0.58 V maximum forward voltage at 2 A, enabling high-efficiency power conversion in compact, high-density PCB layouts.
For engineers reviewing the CMS14(TE12L,Q,M) datasheet, CMS14(TE12L,Q,M) pinout, CMS14(TE12L,Q,M) application, or CMS14(TE12L,Q,M) equivalent, key selection criteria include thermal resistance (60 °C/W on ceramic board), junction capacitance (77 pF at 10 V), reverse leakage (200 µA max at 60 V), and suitability for RF rectification under pulsed and continuous conduction conditions.
Technical Context
The CMS14(TE12L,Q,M) employs a planar Schottky junction structure with low series resistance and minimal stored charge, enabling fast recovery and reduced switching losses. Its 77 pF junction capacitance at 10 V supports stable operation up to several hundred MHz in RF rectifier stages.
Thermal performance is highly dependent on PCB mounting: Rth(j-a) ranges from 60 °C/W (ceramic board, 2 mm × 2 mm land) to 210 °C/W (glass-epoxy, minimal 2.1 mm × 1.4 mm land), requiring layout-aware derating per Toshiba's reliability guidelines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum reverse blocking capability without breakdown under repetitive conditions |
| IF(AV) | 2.0 A - Continuous forward current rating at Tℓ = 112°C on specified ceramic board |
| VFM | 0.58 V (max) at IFM = 2 A - Low conduction loss critical for efficiency in 5–12 V output DC-DC stages |
| IRRM | 200 µA (max) at VRRM = 60 V - Reverse leakage directly impacts standby power and thermal stability |
| Cj | 77 pF at VR = 10 V, 1 MHz - Junction capacitance limits high-frequency noise coupling and switching speed |
| Rth(j-a) | 60 °C/W - Thermal resistance on standard 50 mm × 50 mm ceramic board defines safe operating area under load |

|---|---|---|
| 1 | Anode | Forward current entry point; connects to input/high-side node in buck or boost rectifier path |
| 2 | Cathode | Forward current exit point; ties to ground or output node; also serves as primary heat-sinking terminal |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage drop | VFM ≤ 0.58 V at 2 A enables ≥92% efficiency in 5 V/2 A synchronous-buck secondary-side rectification |

Applications
| Switching Regulator Output Rectification | DC-DC Converter Freewheeling Diode |
|---|---|
Use Scenario: Secondary-side rectification in non-isolated buck converters delivering 3.3–12 V at up to 2 A. IC Role / Device Role / Timing Role: Uncontrolled rectifier conducting during low-side switch off-time; handles full output current with minimal conduction loss. Use Value: 0.58 V VFM reduces power dissipation by ~18% versus comparable 0.7 V diodes, lowering thermal stress on adjacent ICs. | Use Scenario: Freewheeling path in step-down regulators where synchronous MOSFETs are omitted or impractical. IC Role / Device Role / Timing Role: Provides low-loss current recirculation path during high-side switch off-phase; operates at switching frequency with minimal ringing. Use Value: 77 pF Cj minimizes capacitive coupling of switching edges into feedback networks, improving regulation stability. |
| RF Energy Harvesting Rectifier | High-Density Point-of-Load Module |
Use Scenario: AC-to-DC conversion of harvested RF signals (e.g., 900 MHz ISM band) in ultra-low-power sensor nodes. IC Role / Device Role / Timing Role: Single-diode half-wave rectifier converting modulated RF envelope into usable DC bias. Use Value: Sub-1 V forward threshold and low Cj enable efficient rectification of weak, high-Z RF sources with minimal insertion loss. | Use Scenario: Embedded power module for FPGA or ASIC core rails where board space is constrained to <10 mm² per rail. IC Role / Device Role / Timing Role: Compact, thermally efficient rectifier placed adjacent to controller IC in integrated POL architecture. Use Value: SOD-123FL package with 60 °C/W Rth(j-a) on ceramic allows 2 A operation within 150°C Tj limit without heatsink or airflow. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB050M-30TR | Higher VRRM (100 V), higher VFM (0.75 V @ 2 A), same SOD-123FL package | Better suited for 24 V input systems; less efficient at 5–12 V outputs due to higher conduction loss | Select RB050M-30TR only when reverse voltage margin >60 V is required; CMS14(TE12L,Q,M) remains optimal for 5–12 V DC-DC stages |
| SS24-HF | Lower IF(AV) (1.5 A), same VRRM (60 V), slightly higher VFM (0.59 V), SOD-123 package (not FL variant) | Reduced thermal margin on small PCBs; no M-FLAT™ low-profile advantage for ultra-thin modules | SS24-HF may be used in cost-sensitive, lower-current designs but lacks the thermal robustness and footprint optimization of CMS14(TE12L,Q,M) |
Compared with RB050M-30TR and SS24-HF, the CMS14(TE12L,Q,M) offers the best balance of low forward voltage, verified 2 A capability on ceramic boards, and M-FLAT™ thermal performance-making it preferred for high-efficiency, space-constrained DC-DC rectification where 60 V reverse rating suffices.

FAQ
What is the maximum average forward current rating for CMS14(TE12L,Q,M)?
The CMS14(TE12L,Q,M) has an average forward current rating of 2.0 A, specified at a lead temperature of 112°C when mounted on a 50 mm × 50 mm ceramic board with a 2 mm × 2 mm solder land and 0.64 mm thickness. This rating assumes rectangular waveform conduction (α = 180°) and must be derated under higher ambient temperatures or different board configurations.
Does CMS14(TE12L,Q,M) have a documented thermal resistance value for standard FR-4 PCBs?
Yes - CMS14(TE12L,Q,M) specifies Rth(j-a) = 135 °C/W when mounted on a 50 mm × 50 mm glass-epoxy (FR-4) board with a 6 mm × 6 mm solder land and 1.6 mm thickness. For smaller land patterns (2.1 mm × 1.4 mm), Rth(j-a) rises to 210 °C/W, requiring careful thermal design in dense layouts.
What is the peak forward voltage of CMS14(TE12L,Q,M) under typical operating conditions?
The CMS14(TE12L,Q,M) exhibits a typical peak forward voltage of 0.53 V at 2 A (pulse test), with a maximum of 0.58 V. This value is measured under short-pulse conditions (Ta = 25°C) and reflects the diode's low-conduction-loss performance critical for high-efficiency DC-DC conversion.
Can CMS14(TE12L,Q,M) be used in RF rectification applications above 100 MHz?
Yes - CMS14(TE12L,Q,M) is explicitly rated for radio-frequency rectification, with a junction capacitance of 77 pF at 10 V and 1 MHz. Its low stored charge and Schottky construction support stable operation in RF energy harvesting and envelope detection circuits up to several hundred MHz, provided layout parasitics are minimized.
Is CMS14(TE12L,Q,M) RoHS compliant and halogen-free?
Yes - CMS14(TE12L,Q,M) complies with the EU RoHS Directive and is halogen-free, as confirmed by Toshiba's environmental compliance documentation. Full material declarations and test reports are available through Toshiba's official website or authorized distribution channels upon request.
