Toshiba Semiconductor and Storage CRS15I30A(TE85L,QM

Overview

CRS15I30A from TOSHIBA is a Schottky barrier rectifier optimized for secondary-side rectification in DC-DC switching regulators and reverse-current protection in mobile devices. It delivers V_F(max) = 0.46 V at 1.5 A, supports 30 V repetitive peak reverse voltage (V_RRM), and operates with 1.5 A average forward current (I_F(AV)) on ceramic board mounting.

For engineers reviewing the CRS15I30A datasheet, CRS15I30A pinout, CRS15I30A application, or CRS15I30A equivalent, key selection criteria include low forward voltage for efficiency-critical 30 V-class power rails, thermal resistance of 70 °C/W (ceramic board), junction temperature rating up to 150 °C, and S-FLAT™ surface-mount package compatibility with high-density PCB layouts.

Technical Context

The CRS15I30A employs a planar Schottky barrier structure enabling fast recovery (no minority-carrier storage) and low conduction loss. Its 30 V V_RRM and 1.5 A I_F(AV) target mid-voltage secondary-side rectification where efficiency and thermal management are critical.

Electrical behavior is characterized by low V_F (0.40 V typ. / 0.46 V max at 1.5 A), low junction capacitance (50 pF typ. at 10 V), and reverse leakage under 60 µA at rated V_RRM, supporting stable operation in compact, thermally constrained mobile and portable power designs.

Key Specifications

Pinout & Package

CRS15I30A uses the S-FLAT™ surface-mount package (TOSHIBA code 3-2A1A), measuring 3.5 × 2.6 × 0.98 mm, with anode and cathode terminals exposed on opposite ends for low-inductance PCB layout.

FAQ

What is the maximum junction temperature rating for CRS15I30A?

The CRS15I30A has a maximum junction temperature (T_j) rating of 150 °C. This allows operation in thermally demanding environments such as sealed smartphone chassis or wearable enclosures. For reliable long-term use, Toshiba recommends limiting T_j to ≤120 °C via appropriate board-level thermal design-especially when using the CRS15I30A on glass-epoxy substrates where R_th(j-a) rises to 140 °C/W.

Does CRS15I30A support high-frequency switching applications?

Yes, the CRS15I30A supports high-frequency switching applications up to 1 MHz due to its Schottky barrier construction and low junction capacitance (50 pF typ. at 10 V). Its lack of minority-carrier storage eliminates reverse recovery time, minimizing switching losses and EMI in DC-DC converters operating above 500 kHz-making CRS15I30A well-suited for modern compact power supplies.

What is the forward voltage specification of CRS15I30A at 1.5 A?

The CRS15I30A specifies a maximum forward voltage (V_F) of 0.46 V at 1.5 A pulsed test condition (Ta = 25°C). Typical V_F is 0.40 V under the same condition. This low V_F directly reduces conduction loss in power paths, improving overall efficiency-particularly valuable in battery-operated devices where every milliwatt counts.

Is CRS15I30A RoHS compliant and halogen-free?

Yes, the CRS15I30A meets RoHS Directive 2011/65/EU requirements and is halogen-free per JESD209-4. Toshiba confirms compliance in its official environmental documentation, and the device carries appropriate marking. Customers must verify final compliance status against the latest revision of Toshiba's environmental reports, as material declarations may be updated based on regulatory changes.

What is the recommended PCB land pattern for CRS15I30A?

Toshiba specifies a reference land pattern for CRS15I30A with 2.0 mm × 2.0 mm solder pads on a 50 mm × 50 mm ceramic board for optimal thermal performance (R_th(j-a) = 70 °C/W). The actual land dimensions shown in the datasheet are 2.8 mm (length) × 1.2 mm (width) per pad, with 1.2 mm spacing between pads. Deviations affect thermal resistance and must be validated per application requirements.
