Product details
Overview
CRS01(TE85L) from TOSHIBA is a Schottky barrier rectifier optimized for high-speed, low-loss DC power conversion in compact surface-mount applications. It delivers 1.0 A average forward current, 30 V repetitive peak reverse voltage, and a low 0.37 V forward voltage at 0.7 A, making it suitable for USB power delivery, portable charger circuits, and low-voltage DC-DC converter outputs.
For engineers reviewing the CRS01(TE85L) datasheet, CRS01(TE85L) pinout, CRS01(TE85L) application, or CRS01(TE85L) equivalent, key selection criteria include thermal resistance (Rth(j-a) = 70°C/W on ceramic board), junction capacitance (40 pF at 10 V), surge current capability (22 A at 60 Hz), and VF–IR trade-off behavior requiring careful thermal design under reverse bias.
Technical Context
The CRS01(TE85L) employs a planar Schottky barrier structure with metal–semiconductor junction physics enabling fast switching (no minority-carrier storage) and low conduction loss. Its VF–IR trade-off is intrinsic: lower forward voltage (0.33 V typ. @ 0.7 A) correlates with higher reverse leakage (≤1.5 mA @ 30 V), necessitating derating above 85°C ambient.
Thermal performance is mounting-dependent: Rth(j-a) ranges from 70°C/W (ceramic board, 2 mm × 2 mm pad) to 140°C/W (glass-epoxy, 6 mm × 6 mm pad). Junction temperature must be kept below 100°C for reliable operation, per Toshiba's derating guidance for average forward current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum non-repetitive reverse voltage before breakdown; requires ≥20% margin over system rail (e.g., ≤24 V nominal input) |
| IF(AV) | 1.0 A - Continuous DC output current capability with proper PCB thermal design (e.g., ≥2 mm² copper pour) |
| VFM @ 0.7 A | 0.37 V max - Directly reduces conduction loss: ~0.26 W dissipation at 0.7 A, critical for thermally constrained layouts |
| IFSM (60 Hz) | 22 A - Surge rating for brief inrush events (e.g., capacitor charging); not for repetitive use |
| Cj @ 10 V | 40 pF - Limits high-frequency switching noise and EMI in SMPS output stages |
| Rth(j-a) ceramic | 70°C/W - Enables 1.0 A operation up to ~75°C ambient when mounted on 2 mm × 2 mm ceramic substrate |
| Tj range | −40°C to +125°C - Specifies full operational junction temperature envelope; reliability derating recommended above 100°C |
Pinout & Package
CRS01(TE85L) uses Toshiba's S-FLAT™ package (JEITA code 3-2A1A), a 2-pin surface-mount plastic molded case measuring 2.8 mm × 1.2 mm × 1.2 mm, weighing 0.013 g. The device has anode and cathode terminals only; polarity is marked by a band on the cathode end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input terminal for forward current flow | Connected to higher-potential node (e.g., SMPS switch node or input rail); determines forward conduction direction |
| Cathode | Output terminal for forward current flow | Connected to load or output capacitor; marked with band; carries full IF(AV) and must route heat to PCB copper |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | 0.37 V max @ 0.7 A - Reduces power loss by >40% vs. standard PN diodes in same footprint |
| High-speed unipolar conduction | No reverse recovery time (trr ≈ 0 ns) - Eliminates switching loss and ringing in high-frequency converters (>500 kHz) |
| Compact S-FLAT™ package | 2.8 × 1.2 × 1.2 mm - Enables ultra-dense layout in space-constrained USB-C PD adapters and wearables |
| Controlled VF–IR trade-off | Specified IRRM ≤1.5 mA @ 30 V - Requires thermal-aware layout to prevent runaway under high VR + high Ta |
| Robust surge rating | 22 A non-repetitive peak @ 60 Hz - Withstands typical AC line rectification surges without failure |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB050M-30TR | Higher VRRM (30 V same), but higher VFM (0.45 V max @ 0.7 A); Rth(j-a) = 90°C/W on same board | Better reverse ruggedness, worse conduction loss and thermal performance | Prefer RB050M-30TR only if system reverse transients exceed 25 V and layout allows larger thermal pad |
| SS12 | Same package (SOD-123), but lower IF(AV) = 0.5 A and higher VFM = 0.5 V max @ 0.5 A | Lower cost, lower current capacity; unsuitable for sustained 1.0 A loads | Select SS12 only for <0.4 A average current applications where cost outweighs efficiency and thermal margin |
Compared with RB050M-30TR and SS12, CRS01(TE85L) offers the best balance of low VFM, 1.0 A rating, and ceramic-board thermal resistance-making it optimal for space- and efficiency-constrained 5–12 V DC-DC outputs where junction temperature must stay below 100°C.

FAQ
What is the maximum continuous forward current rating for CRS01(TE85L)?
The CRS01(TE85L) has an average forward current rating of 1.0 A under specified thermal conditions: rectangular waveform (conduction angle α = 180°), case temperature Tℓ = 98°C, and reverse voltage VR = 15 V. This rating assumes proper PCB thermal design-e.g., 2 mm × 2 mm solder land on ceramic substrate-to maintain junction temperature below 100°C. Exceeding this current without adequate heatsinking risks thermal runaway due to its VF–IR trade-off nature.
Does CRS01(TE85L) have a specified reverse recovery time (trr)?
No-CRS01(TE85L) is a Schottky barrier rectifier and therefore exhibits no minority-carrier storage delay. Its reverse recovery time is effectively zero (trr ≈ 0 ns), unlike PN-junction rectifiers. This eliminates reverse recovery loss and associated switching noise, making CRS01(TE85L) ideal for high-frequency DC-DC converters operating above 500 kHz where trr-induced losses dominate.
What is the thermal resistance from junction to ambient for CRS01(TE85L) on a standard PCB?
CRS01(TE85L) has two specified Rth(j-a) values depending on mounting: 70°C/W when mounted on a ceramic board with 2 mm × 2 mm solder land, and 140°C/W on a glass-epoxy board with 6 mm × 6 mm land. These values reflect real-world thermal performance-not theoretical limits-and must be used with actual board layout data to calculate junction temperature under load.
Can CRS01(TE85L) be used in automotive applications?
CRS01(TE85L) is not qualified for automotive applications per AEC-Q101. Its specified operating junction temperature range (−40°C to +125°C) meets ambient requirements, but Toshiba explicitly excludes automotive use in its Restrictions on Product Use notice. For automotive-grade alternatives, consult Toshiba's AEC-Q101-certified Schottky rectifier portfolio-CRS01(TE85L) is intended for industrial, consumer, and computing power supplies only.
How does the VF–IR trade-off affect circuit design with CRS01(TE85L)?
The CRS01(TE85L) is designed as a VF–IR trade-off type: its low 0.33 V typical forward voltage correlates with higher reverse leakage (≤1.5 mA at 30 V). This means reverse-biased power dissipation increases significantly at elevated temperatures, potentially triggering thermal runaway if voltage and ambient temperature are both high. Designers must perform combined VF/IR thermal analysis and apply derating-e.g., limiting VR to ≤20 V at Ta > 85°C-to ensure stable operation.
