Product details
Overview
CRH01(TE85R,Q,M) from TOSHIBA is a high-efficiency silicon epitaxial fast recovery rectifier diode designed for switching-mode power supply (SMPS) output rectification. It delivers 1 A average forward current, 200 V repetitive peak reverse voltage, and ultra-fast 35 ns reverse recovery time, enabling high-frequency operation in compact AC/DC adapters and DC/DC converters.
For engineers reviewing the CRH01(TE85R,Q,M) datasheet, CRH01(TE85R,Q,M) pinout, CRH01(TE85R,Q,M) application, or CRH01(TE85R,Q,M) equivalent, key selection criteria include forward voltage drop at 1 A (≤0.98 V), thermal resistance on ceramic board (65 °C/W), junction temperature range (−40 to +150 °C), and S-FLAT™ surface-mount package compatibility with automated assembly.
Technical Context
This device uses a silicon epitaxial planar structure optimized for fast switching and low conduction loss. Its 35 ns reverse recovery time and 0.90 V typical forward voltage at 1 A support high-efficiency rectification in 100–500 kHz SMPS topologies, minimizing switching losses and thermal stress.
The CRH01(TE85R,Q,M) operates across −40 to +150 °C junction temperature and exhibits low leakage (≤10 µA at 200 V), making it suitable for thermally constrained environments where reliability under transient surge (15 A non-repetitive peak) must be maintained without derating beyond 80% of absolute maximum ratings.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum blocking voltage in reverse bias; supports 170 VAC input rectification with 50% safety margin per Toshiba derating guidance for AC circuits. |
| IF(AV) | 1 A - Continuous DC output current capability; requires thermal design ensuring Tj ≤ 120 °C under worst-case ambient conditions. |
| VFM (1 A) | 0.98 V max - Forward voltage at rated current; directly determines conduction loss (≤0.98 W at 1 A) and impacts system efficiency. |
| trr | 35 ns max - Reverse recovery time measured at IF = 1 A, di/dt = −30 A/µs; enables stable operation up to ~3 MHz effective switching frequency. |
| Rth(j-a) | 65 °C/W - Junction-to-ambient thermal resistance on ceramic board (50×50 mm, 2×2 mm pad); defines minimum heatsinking needed for 1 A continuous operation. |
| Tj Range | −40 to +150 °C - Operational junction temperature window; supports industrial-grade deployment without active cooling in sealed enclosures. |
Pinout & Package
The CRH01(TE85R,Q,M) is housed in Toshiba's proprietary S-FLAT™ surface-mount package (JEITA package code 3-2A1A), measuring 2.8 × 1.2 × 1.2 mm, with gull-wing leads optimized for reflow soldering and compact PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Forward current entry point | Connected to switching node (e.g., transformer secondary or MOSFET drain) in flyback or forward converters; carries full load current during conduction phase. |
| Cathode (K) | Forward current exit point | Connected to output capacitor and load; polarity-sensitive terminal-reverse connection causes catastrophic failure under reverse bias. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-fast recovery | trr ≤ 35 ns ensures minimal switching loss and EMI generation in high-frequency SMPS designs above 200 kHz. |
| Low forward voltage | VFM ≤ 0.98 V at 1 A reduces conduction loss by ~15% versus standard FR1 diodes, improving efficiency in 5–24 V output rails. |
| S-FLAT™ package | 2.8 × 1.2 mm footprint enables >30% board area reduction vs. SMA packages, supporting ultra-compact USB-C PD and IoT power modules. |
| High surge tolerance | IFSM = 15 A (50 Hz half-sine) withstands inrush and fault transients without bond-wire fusing, enhancing system robustness. |
Applications
| AC/DC Adapters | DC/DC Converters |
|---|---|
Use Scenario: 5–65 W universal-input offline adapters for consumer electronics (e.g., monitors, set-top boxes). IC Role / Device Role / Timing Role: Output rectifier in flyback topology, synchronously replacing Schottky diodes where higher voltage rating is required. Use Value: Enables 89–92% efficiency at full load due to low VFM and fast trr, meeting DOE Level VI and CoC Tier 2 requirements without active clamp. | Use Scenario: Isolated 12 V → 3.3 V/5 V step-down converters in industrial PLC I/O modules. IC Role / Device Role / Timing Role: Secondary-side rectifier in forward or push-pull converters operating at 250–400 kHz switching frequency. Use Value: Reduces thermal rise by 12 °C versus UF1J (trr = 50 ns) under identical layout and load, eliminating need for thermal vias. |
| LED Drivers | Automotive Infotainment Power Supplies |

IC Role / Device Role / Timing Role: Rectifier in primary-side controlled buck-boost or SEPIC stages handling 100–277 VAC input. Use Value: Maintains <10 µA reverse leakage at 125 °C ambient, preventing false triggering of overvoltage protection during thermal cycling. | Use Scenario: 12 V battery-fed power supplies for head units and display controllers in passenger vehicles. IC Role / Device Role / Timing Role: Input rectifier in dual-output (5 V/3.3 V) isolated DC/DC modules compliant with ISO 7637-2 pulse 5a/b. Use Value: Withstands 15 A surge pulses without degradation, satisfying automotive load-dump immunity requirements without external TVS. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ROHM RB055LAM-40 | Lower VRRM (40 V), higher IF(AV) (1.5 A), trr = 30 ns, same SOD-123FL package | Restricted to low-voltage DC/DC outputs (<24 V); unsuitable for AC line rectification | Select only when VRRM ≤ 40 V suffices and lower VFM (0.45 V typ.) is prioritized over voltage rating. |
| Vishay VS-1EWH02-M3/5AT | Same VRRM (200 V), IF(AV) = 1 A, trr = 30 ns, DO-214AC (SMA) package (4.5 × 2.7 mm) | Larger footprint increases board area by 2.8×; higher Rth(j-a) (~100 °C/W) limits power density | Choose only if legacy SMA footprint compatibility is mandatory and thermal margin allows larger heatsinking. |
Compared with ROHM RB055LAM-40 and Vishay VS-1EWH02-M3/5AT, the CRH01(TE85R,Q,M) uniquely balances 200 V rating, 1 A current, 35 ns recovery, and ultra-compact S-FLAT™ packaging-enabling highest power density in space-constrained SMPS designs where both voltage headroom and thermal performance are critical.

FAQ
What is the maximum junction temperature rating for CRH01(TE85R,Q,M)?
The CRH01(TE85R,Q,M) has an absolute maximum junction temperature (Tj) of +150 °C, but Toshiba recommends limiting steady-state operation to ≤120 °C for high reliability. This derating ensures long-term stability under continuous 1 A load and accounts for thermal resistance variations across PCB materials and land patterns.
Does CRH01(TE85R,Q,M) support lead-free reflow soldering?
Yes, the CRH01(TE85R,Q,M) is qualified for lead-free reflow soldering per JEDEC J-STD-020. Its S-FLAT™ package withstands peak temperatures up to 260 °C for 10 seconds, and the device meets RoHS Directive 2011/65/EU requirements with no exemptions applied.
What is the reverse recovery time test condition for CRH01(TE85R,Q,M)?
The CRH01(TE85R,Q,M) reverse recovery time (trr) is specified as ≤35 ns under the condition: IF = 1 A, di/dt = −30 A/µs, with measurement performed using pulse testing methods per JEDEC standards. This reflects real-world behavior in high-frequency SMPS circuits with steep current fall rates.
Can CRH01(TE85R,Q,M) replace standard 1N4007 diodes in AC line rectification?
No-while both handle 200 V reverse voltage, the CRH01(TE85R,Q,M) is optimized for high-frequency switching (trr = 35 ns), not 50/60 Hz line frequency. Using it in place of 1N4007 in bridge rectifiers offers no benefit and risks overstress due to its lower IFSM rating (15 A vs. 30 A) and smaller thermal mass.
What is the thermal resistance of CRH01(TE85R,Q,M) on a standard FR-4 PCB?
When mounted on a glass-epoxy (FR-4) board per Toshiba's reference layout (50×50 mm, 6×6 mm solder land, 1.6 mm thickness), the CRH01(TE85R,Q,M) exhibits Rth(j-a) = 130 °C/W. This value must be used in thermal calculations for continuous 1 A operation in non-ventilated enclosures.
