Product details

Overview

CRS05(TE85L,Q,M) from Toshiba is a Schottky barrier diode optimized for secondary rectification in DC-DC switching regulators and reverse-current protection in portable electronics. It delivers V_RRM = 30 V, I_F(AV) = 1.0 A (at T_a = 102°C on ceramic board), V_FM ≤ 0.45 V @ 1.0 A, I_RRM ≤ 5 μA @ 5 V, and uses the ultra-thin S-FLAT™ package for high-density PCB layouts.

For engineers reviewing the CRS05(TE85L,Q,M) datasheet, CRS05(TE85L,Q,M) pinout, CRS05(TE85L,Q,M) application, or CRS05(TE85L,Q,M) equivalent, key selection criteria include low forward voltage for efficiency-critical 3.3 V/5 V output rails, low leakage under light-load conditions, thermal performance on ceramic vs. FR-4 substrates, and compatibility with automated SMT assembly of 2.8 mm × 1.2 mm footprints.

Technical Context

This Schottky diode leverages a planar metal–semiconductor junction to achieve fast recovery (no minority-carrier storage) and low conduction loss. Its V_FM remains stable across 0.1–1.0 A pulse currents, and I_RRM increases predictably with reverse voltage-2.0–5.0 μA at 5 V, up to 200 μA at 30 V-enabling accurate loss modeling in buck converter freewheeling paths.

The device's thermal behavior is defined by two R_th(j-a) values: 70°C/W on 2 mm × 2 mm ceramic land and 140°C/W on 6 mm × 6 mm glass-epoxy land. Junction temperature must be derated below 150°C, with recommended operation below 120°C to ensure reliability under continuous 1.0 A load.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	30 V - Supports input-to-output differential up to 30 V in 24 V-input buck converters with 5 V/3.3 V outputs.
I_F(AV)	1.0 A - Rated for continuous conduction at 102°C ambient on ceramic board; requires ≥2 mm × 2 mm copper pad for thermal compliance.
V_FM	≤0.45 V @ 1.0 A - Reduces conduction loss to ≤450 mW, critical for >90% efficiency in low-voltage, high-current POL supplies.
I_RRM	≤5 μA @ 5 V - Enables low standby power in battery-powered devices with reverse-blocking requirements.
C_j	60 pF @ 10 V - Limits high-frequency switching noise and ringing in MHz-range converters.
R_th(j-a)	70°C/W (ceramic) / 140°C/W (FR-4) - Dictates minimum PCB copper area needed to maintain T_j < 120°C at full load.

Pinout & Package

The CRS05(TE85L,Q,M) uses the S-FLAT™ package (JEITA code 3-2A1S), measuring 2.8 mm × 1.2 mm × 0.9 mm with gull-wing leads. It is a 2-terminal surface-mount device with exposed cathode pad for thermal enhancement.

Pin/Terminal	Circuit Role	Design Meaning
1	Anode	Connects to switch node (e.g., MOSFET drain) in synchronous or asynchronous buck topologies.
2	Cathode	Connects to output rail; large solder land required for heat dissipation and low-inductance return path.

Key Features

Feature	Design Value
Ultra-low V_FM	0.42 V typical @ 1.0 A enables ≥0.5% efficiency gain over standard 0.55 V Schottkys in 5 V/1 A converters.
S-FLAT™ package	2.8 mm × 1.2 mm footprint saves >40% board area vs. SMA/SOD-123, enabling compact USB-C PD and PMIC designs.
Low I_RRM at low VR	2.0–5.0 μA @ 5 V ensures <10 μW reverse leakage in always-on battery backup paths.
High I_FSM	20 A non-repetitive surge rating withstands startup inrush and transient overload without bond-wire fusing.

Applications

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	V_RRM = 30 V, I_F(AV) = 0.5 A, V_FM = 0.47 V @ 0.5 A, SOD-523 package (1.6 mm × 0.8 mm)	Lower current rating and smaller footprint; suitable only for ≤0.5 A loads.	Select RB050M-30TR when board space is constrained and peak load is <0.5 A; CRS05(TE85L,Q,M) remains preferred for 1 A continuous duty.
SS12	V_RRM = 20 V, I_F(AV) = 1.0 A, V_FM = 0.5 V @ 1.0 A, SMA package (4.5 mm × 2.7 mm)	Lower V_RRM, higher V_FM, larger package; less efficient and less dense than CRS05(TE85L,Q,M).	Choose SS12 only if legacy SMA footprint compatibility is mandatory and 20 V rating suffices; CRS05(TE85L,Q,M) offers superior efficiency and miniaturization.

Compared with RB050M-30TR and SS12, the CRS05(TE85L,Q,M) uniquely balances 1.0 A current capability, 30 V rating, 0.45 V V_FM, and 2.8 mm × 1.2 mm S-FLAT™ packaging-making it optimal for space-constrained, high-efficiency 1 A DC-DC outputs where thermal management on ceramic substrates is feasible.

FAQ

What is the maximum allowable junction temperature for CRS05(TE85L,Q,M)?

The absolute maximum junction temperature (T_j) for CRS05(TE85L,Q,M) is 150°C. Toshiba recommends operating below 120°C (80% of max) to ensure long-term reliability. Derating curves in the datasheet show that at 1.0 A average current, ambient temperature must be limited to 102°C on ceramic board or 54.7°C on FR-4 to stay within this margin. Exceeding T_j = 120°C accelerates parameter drift and reduces lifetime.

Does CRS05(TE85L,Q,M) support reflow soldering per J-STD-020?

Yes, CRS05(TE85L,Q,M) is qualified for lead-free reflow soldering per J-STD-020D. Its S-FLAT™ package withstands peak temperatures up to 260°C for 10 seconds. The device's moisture sensitivity level (MSL) is not specified in the provided documentation, but standard handling for MSL 1 applies unless otherwise noted by Toshiba. Always verify latest MSL rating via Toshiba's official product page before production.

How does thermal resistance vary between PCB substrate types for CRS05(TE85L,Q,M)?

CRS05(TE85L,Q,M) exhibits R_th(j-a) = 70°C/W on a 50 mm × 50 mm ceramic board with 2 mm × 2 mm solder land, versus 140°C/W on an identical-size glass-epoxy board with 6 mm × 6 mm land. This 2× difference means the same 1.0 A load generates twice the temperature rise on FR-4. Designers must adjust copper area or add thermal vias accordingly-especially critical in sealed enclosures or high-ambient environments.

Is CRS05(TE85L,Q,M) RoHS compliant and halogen-free?

Yes, CRS05(TE85L,Q,M) complies with EU RoHS Directive 2011/65/EU and is halogen-free per Toshiba's environmental specifications. The device contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE above threshold limits. Full material declarations and test reports are available through Toshiba's official website or authorized distributors upon request.

What is the reverse recovery time (t_rr) of CRS05(TE85L,Q,M)?

The CRS05(TE85L,Q,M) is a Schottky barrier diode and therefore has no minority-carrier storage delay-its reverse recovery is effectively instantaneous (<1 ns). Unlike PN-junction diodes, it exhibits no t_rr specification because conduction ceases immediately upon voltage reversal. This eliminates switching loss and EMI associated with reverse recovery charge (Q_rr), making CRS05(TE85L,Q,M) ideal for high-frequency DC-DC converters.
