Toshiba Semiconductor and Storage CMS07(TE12L,Q,M)

Overview

CMS07(TE12L,Q,M) from TOSHIBA is a Schottky barrier rectifier optimized for high-efficiency, low-voltage DC/DC conversion in compact power supplies. It delivers 2.0 A average forward current, 30 V repetitive peak reverse voltage, and a maximum forward voltage of 0.45 V at 2.0 A - enabling reduced conduction loss in portable equipment battery circuits and switching mode power supplies.

For engineers reviewing the CMS07(TE12L,Q,M) datasheet, CMS07(TE12L,Q,M) pinout, CMS07(TE12L,Q,M) application, or CMS07(TE12L,Q,M) equivalent, key selection criteria include thermal resistance (Rth(j-a) = 60°C/W on ceramic board), junction capacitance (130 pF), surge capability (40 A non-repetitive), and M-FLAT™ surface-mount package compatibility with automated assembly.

Technical Context

The CMS07(TE12L,Q,M) employs a planar Schottky barrier structure to achieve low forward voltage drop and fast switching recovery - critical for minimizing power loss in high-frequency SMPS topologies operating up to several hundred kHz. Its low Rth(j-a) of 60°C/W (on 2 mm × 2 mm ceramic land) supports sustained 2.0 A operation without forced cooling.

Designed for unidirectional power conversion, it exhibits no minority-carrier storage delay and negligible reverse recovery charge (Qrr ≈ 0), eliminating snubber requirements in synchronous rectifier and OR-ing applications. Reverse leakage remains under 500 µA at 30 V and 25°C, with temperature-dependent rise constrained by its −40°C to +150°C junction rating.

Key Specifications

Pinout & Package

FAQ

What is the maximum junction temperature rating for CMS07(TE12L,Q,M)?

The CMS07(TE12L,Q,M) has a specified junction temperature range of −40°C to +150°C. For reliable long-term operation, Toshiba recommends limiting steady-state Tj to ≤120°C using appropriate derating - especially when operating near IF(AV) = 2.0 A or under elevated ambient conditions. Thermal design must account for actual Rth(j-a) based on PCB layout, as values vary significantly between ceramic and glass-epoxy substrates.

Is CMS07(TE12L,Q,M) suitable for synchronous rectification in high-frequency SMPS?

Yes, CMS07(TE12L,Q,M) is well-suited for synchronous rectification in high-frequency SMPS due to its Schottky barrier construction, which eliminates reverse recovery charge (Qrr ≈ 0) and enables clean, fast turn-off. Its 130 pF junction capacitance and 0.45 V forward voltage minimize switching losses and EMI in converters operating up to 1 MHz - provided gate drive timing avoids shoot-through during dead-time intervals.

What does the marking "S7" indicate on CMS07(TE12L,Q,M)?

The marking "S7" on the CMS07(TE12L,Q,M) package is Toshiba's standardized abbreviation code identifying this specific device variant within the CMS07 family. It appears as laser-marked text on the top surface of the M-FLAT™ body and corresponds exclusively to the CMS07(TE12L,Q,M) ordering option - distinguishing it from other suffix variants such as CMS07(TE12L,Q) or CMS07(TE12L).

How does thermal resistance vary with PCB mounting for CMS07(TE12L,Q,M)?

CMS07(TE12L,Q,M) exhibits Rth(j-a) = 60°C/W when mounted on a 50 mm × 50 mm ceramic board with 2 mm × 2 mm soldering land, but rises to 135°C/W on a standard glass-epoxy board with 6 mm × 6 mm land. This 125% increase underscores the importance of substrate choice and copper area optimization - undersized pads or low-thermal-conductivity boards can cause premature thermal shutdown even at 1.2 A continuous load.

Does CMS07(TE12L,Q,M) meet RoHS and lead-free soldering requirements?

Yes, CMS07(TE12L,Q,M) complies with EU RoHS Directive 2011/65/EU and is compatible with lead-free reflow soldering profiles (J-STD-020). Toshiba confirms halogen-free construction and specifies peak reflow temperature tolerance up to 260°C for 10 seconds. Full compliance documentation, including material declarations and test reports, is available through authorized Toshiba distributors upon request for CMS07(TE12L,Q,M).
