Product details
Overview
CRS14(TE85L,Q,M) from Toshiba is a Schottky barrier diode optimized for secondary rectification in DC-DC switching regulators and reverse-current protection in mobile devices, with VRRM = 30 V, IF(AV) = 2.0 A at Ta = 64°C, and VFM ≤ 0.49 V @ 2.0 A.
For engineers reviewing the CRS14(TE85L,Q,M) datasheet, CRS14(TE85L,Q,M) pinout, CRS14(TE85L,Q,M) application, or CRS14(TE85L,Q,M) equivalent, key selection factors include low forward voltage drop, thermal resistance of 70°C/W on ceramic board, junction temperature range (−40 to 150°C), and S-FLAT™ package compatibility with high-density PCB layouts.
Technical Context
The CRS14(TE85L,Q,M) employs a planar Schottky barrier structure enabling fast switching with negligible reverse recovery charge, making it suitable for high-frequency (>100 kHz) synchronous rectification. Its low VFM minimizes conduction loss in 3.3 V–12 V output rails.
Thermal performance is defined for two mounting conditions: Rth(j-a) = 70°C/W on 50 mm × 50 mm ceramic board with 2 mm × 2 mm solder land, and 140°C/W on glass-epoxy board - requiring layout-aware derating per Toshiba's reliability guidelines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum repetitive reverse voltage before breakdown; sets upper limit for output capacitor voltage rating in buck converters. |
| IF(AV) | 2.0 A at Ta = 64°C - Continuous forward current capability under defined board thermal conditions; requires ≥2 mm × 2 mm copper land on ceramic substrate. |
| VFM | 0.49 V max @ IF = 2.0 A - Low forward voltage reduces power loss (≤0.98 W) and improves efficiency in portable power stages. |
| Cj | 90 pF @ VR = 10 V - Junction capacitance impacts high-frequency switching noise and EMI; compatible with <1 MHz operation. |
| Tj Range | −40 to 150°C - Operational junction temperature window; derating required above 120°C for long-term reliability. |
| Rth(j-a) | 70°C/W - Thermal resistance on ceramic board defines maximum allowable power dissipation (≈1.43 W) at Ta = 64°C. |
Pinout & Package
CRS14(TE85L,Q,M) uses the S-FLAT™ (TOSHIBA 3-2A1S) surface-mount package: ultra-thin, leadless, 2-pin design measuring 2.8 mm × 1.2 mm × 0.9 mm (L × W × H), weighing 0.013 g (typ.).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Anode) | Anode connection | Connects to switch node or input rail; carries full load current during forward conduction phase. |
| 2 (Cathode) | Cathode connection | Connects to output rail or ground return path; must be routed with low-inductance trace to minimize voltage spikes. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | VFM ≤ 0.49 V @ 2.0 A enables >92% efficiency in 5 V/2 A buck converter output stage. |
| S-FLAT™ package | 2.8 mm × 1.2 mm footprint supports high-density mobile PCB layouts without compromising thermal performance. |
| Fast switching | Negligible reverse recovery time eliminates switching losses and ringing in high-frequency SMPS designs. |
| High surge tolerance | IFSM = 30 A (50 Hz half-sine) withstands inrush and transient overloads in battery-powered systems. |
Applications
| USB Power Delivery Adapter | Smartphone PMIC Output Stage |
|---|---|
Use Scenario: Secondary-side rectification in 20–30 W GaN-based USB PD adapters operating at 200–500 kHz. IC Role / Device Role: Freewheeling diode replacing synchronous MOSFET in cost-sensitive designs; handles 3.3–20 V output rails. Use Value: Reduces BOM count and gate-drive complexity while maintaining <0.5 V forward drop across full load range. |
Use Scenario: Reverse-current blocking between dual battery paths or between PMIC output and system rail in LTE/5G handsets. IC Role / Device Role: Unidirectional isolation diode preventing backfeed from main battery to charging circuit or auxiliary rail. Use Value: Prevents >10 µA standby leakage at 3.8 V, extending battery shelf life without active control logic. |
| Industrial IoT Sensor Node | Wearable Charging Circuit |
Use Scenario: Input rectification for 3.3 V buck-boost charger IC powered by energy-harvesting sources (e.g., solar, RF). IC Role / Device Role: Low-leakage input protection diode ensuring minimal quiescent current draw from micro-power sources. Use Value: IRRM ≤ 50 µA @ 30 V reverse bias preserves harvested energy; Cj = 90 pF avoids signal coupling in analog sensor front-ends. |
Use Scenario: Output isolation in compact wireless charging receiver modules (Qi-compliant) where space limits MOSFET use. IC Role / Device Role: Output rectifier and reverse-polarity protection in 5 V/1 A charging path feeding Li-ion cell management IC. Use Value: 0.49 V VFM limits heat generation in sealed enclosure; S-FLAT™ height <0.9 mm fits sub-8 mm profile wearables. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB050M-30 (ROHM) | VRRM = 30 V, IF(AV) = 2.0 A, VFM = 0.52 V @ 2.0 A, SOD-123FL package (3.5 mm × 1.6 mm) | Larger footprint increases PCB area by 120%; higher VFM raises conduction loss by ~6% at full load. | Preferred when legacy SOD-123FL layout exists and thermal margin exceeds 10°C. |
| SS24 (ON Semiconductor) | VRRM = 40 V, IF(AV) = 2.0 A, VFM = 0.55 V @ 2.0 A, SMA package (4.5 mm × 2.7 mm) | Higher VRRM allows 24 V input compatibility but adds 3× footprint area and 2.5× weight. | Chosen for industrial 24 V systems where voltage headroom outweighs size constraints. |
Compared with RB050M-30 and SS24, CRS14(TE85L,Q,M) delivers the smallest footprint (2.8 mm × 1.2 mm), lowest VFM, and tightest thermal resistance (70°C/W) - critical for space-constrained, thermally sensitive mobile and wearable power designs.

FAQ
What is the maximum ambient temperature for continuous operation of CRS14(TE85L,Q,M)?
The CRS14(TE85L,Q,M) supports continuous operation up to Ta = 64°C when mounted on a 50 mm × 50 mm ceramic board with 2 mm × 2 mm solder land. At higher ambient temperatures, derating is required per the Ta max–IF(AV) curve in the datasheet; exceeding 64°C without adjustment risks junction temperature exceeding 120°C, reducing reliability.
Does CRS14(TE85L,Q,M) have a specified reverse recovery time?
No - the CRS14(TE85L,Q,M) is a Schottky barrier diode and exhibits no minority-carrier storage; its reverse recovery is effectively instantaneous (<1 ns). This eliminates reverse recovery loss and associated EMI, distinguishing it from PN-junction rectifiers used in similar applications.
Can CRS14(TE85L,Q,M) be used in place of a MOSFET for synchronous rectification?
The CRS14(TE85L,Q,M) serves as a passive rectifier and cannot replace a MOSFET in synchronous rectification, which requires active gate control. However, it is a direct alternative to MOSFET-based solutions where simplicity, cost, and zero gate-drive overhead are prioritized over peak efficiency - especially in <3 A, <500 kHz applications.
What is the thermal resistance from junction to lead (Rth(j-ℓ)) for CRS14(TE85L,Q,M)?
The CRS14(TE85L,Q,M) has Rth(j-ℓ) = 20°C/W, measured from junction to solder land. This value enables accurate thermal modeling when the cathode/anode lands are connected to internal copper planes or thermal vias, supporting precise junction temperature estimation under real operating conditions.
Is CRS14(TE85L,Q,M) compliant with RoHS and REACH regulations?
Yes - CRS14(TE85L,Q,M) meets EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Lead-free solderability is confirmed per J-STD-020, and halogen-free status is verified per IEC 61249-2-21. Full compliance documentation is available via Toshiba's official product page.
