Product details
Overview
TRS4E65H from Toshiba Electronic Devices & Storage Corporation is a 650 V, 4 A silicon carbide Schottky barrier diode in TO-220-2L package, featuring VF = 1.2 V (typ.), Qc = 12 nC (typ.), and IR = 0.6 µA (typ.). It serves as a high-efficiency freewheeling or output rectifier in high-frequency switching power stages such as PFC boost converters and solar inverter DC-link circuits.
For engineers reviewing the TRS4E65H datasheet, TRS4E65H pinout, TRS4E65H application, or TRS4E65H equivalent, key selection criteria include its low forward voltage at 4 A, minimal capacitive charge for reduced switching loss, robust 650 V reverse blocking capability, and thermal resistance of 2.50 °C/W (junction-to-case) under rated conditions.
Technical Context
The TRS4E65H implements a third-generation SiC Schottky die architecture optimized for high-voltage, medium-current power conversion. Its unipolar conduction mechanism eliminates minority-carrier storage delay, enabling zero reverse recovery charge (Qrr ≈ 0) and stable switching behavior across temperature.
Designed for hard-switched topologies operating up to 100 kHz, it maintains low IR (< 0.6 µA typ. at VR = 650 V, Ta = 25 °C) and predictable Ct (263 pF typ. at VR = 1 V, f = 1 MHz), supporting consistent EMI performance and snubber design.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 650 V - Sustains full DC-link voltage in 400–600 V bus applications without avalanche stress |
| IF(DC) | 4 A - Continuous conduction rating at TC = 158 °C, suitable for compact heatsink designs |
| VF @ 4 A | 1.2 V (typ.) - Reduces forward conduction loss by ~30% vs. comparable Si fast recovery diodes |
| Qc @ 400 V | 12 nC (typ.) - Limits turn-off energy loss in high-frequency DC-DC and inverter stages |
| IR @ 650 V | 0.6 µA (typ.) - Enables stable operation at elevated temperatures with negligible leakage impact |
| Rth(j-c) | 2.50 °C/W - Allows direct mounting to heatsink with predictable junction temperature rise under load |
Pinout & Package
Package: TO-220-2L (Toshiba designation: 2-10AE1A), single-ended through-hole, isolated tab, weight 1.9 g (typ.). Mounting torque: 0.6 N·m.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Tab) | Cathode | Electrically connected to metal tab; must be electrically isolated from heatsink unless system ground reference permits |
| 2 | Anode | Lead-frame terminal for anode connection; requires PCB trace routing compatible with 4 A continuous current |
Key Features
| Feature | Design Value |
|---|---|
| Third-generation SiC Schottky die | Improved uniformity and edge termination for higher reliability under repetitive surge stress (IFSM = 14 A) |
| Low VF at rated current | 1.2 V typ. at IF = 4 A reduces conduction loss by >1.5 W vs. Si FRD equivalents in 100 kHz PFC stages |
| Negligible Qrr | Zero reverse recovery charge eliminates switching loss spikes and associated EMI in hard-switched converters |
| High Tj rating | 175 °C maximum junction temperature supports operation in sealed industrial enclosures without derating |
Applications
| Power Factor Correction | Solar Inverters |
|---|---|
Use Scenario: Boost PFC stage in 1–3 kW AC-DC front-end for server PSUs or industrial drives. IC Role / Device Role / Timing Role: Output rectifier handling high-frequency (50–100 kHz), discontinuous/continuous conduction mode currents. Use Value: Low Qc (12 nC) and zero Qrr reduce total switching loss by ~40% versus Si alternatives, improving efficiency above 98% at full load. | Use Scenario: DC-link freewheeling path in string inverters with 600 V nominal bus voltage. IC Role / Device Role / Timing Role: Anti-parallel diode for SiC MOSFET half-bridge legs, conducting during dead-time and reactive power flow. Use Value: Stable IR < 0.6 µA at 650 V and 150 °C ensures minimal leakage contribution to thermal runaway risk in unventilated outdoor enclosures. |
| Uninterruptible Power Supplies | DC-DC Converters |
Use Scenario: Bidirectional DC-DC isolation stage in online UPS systems with battery backup and grid synchronization. IC Role / Device Role / Timing Role: High-side synchronous rectifier in dual-active-bridge topology operating at 100–200 kHz. Use Value: VF = 1.2 V (typ.) at 4 A enables >97% peak efficiency while maintaining thermal margin on small heatsinks due to Rth(j-c) = 2.50 °C/W. | Use Scenario: Secondary-side output rectifier in isolated 48 V–12 V telecom DC-DC modules. IC Role / Device Role / Timing Role: Fast-recovery replacement for Si Schottky diodes in high-density, forced-air-cooled modules. Use Value: 650 V VRRM provides 2× voltage margin over 400 V transients, eliminating need for TVS clamping in cost-sensitive designs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar SiC Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPSC406D | Same VRRM (650 V), IF(DC) = 4 A, VF = 1.35 V (max), Qc = 14 nC (typ.), TO-220AC package | Higher VF max and Qc reduce efficiency margin in high-frequency PFC; identical thermal interface but different pinout orientation | Prefer TRS4E65H where VF consistency and lower Qc are critical; STPSC406D acceptable if layout accommodates alternate lead spacing |
| IXYS DSSK40-06A | Dual-die TO-247 package, 650 V/4 A per diode, VF = 1.45 V (max), Qc = 18 nC (typ.), includes integrated thermal pad | Higher footprint and cost; intended for dual-phase or interleaved designs requiring matched pairs | TRS4E65H offers better cost-per-watt and simpler thermal management for single-channel use; DSSK40-06A only when dual-diode integration is required |
Compared with STPSC406D and DSSK40-06A, the TRS4E65H delivers superior conduction efficiency (lower VF typ.) and lower switching loss (reduced Qc), making it optimal for space-constrained, thermally limited 1–3 kW PFC and inverter applications where single-diode simplicity is prioritized.

FAQ
What is the maximum junction temperature rating for the TRS4E65H?
The TRS4E65H has a maximum junction temperature (Tj) rating of 175 °C, verified per Toshiba's absolute maximum ratings table. This allows sustained operation in high-ambient environments such as enclosed UPS cabinets or rooftop solar inverters. Derating is required above Tc = 158 °C per the datasheet's thermal curves, and the device must be mounted with proper thermal interface material to maintain safe Tj under full IF(DC) load.
Does the TRS4E65H have a specified reverse recovery charge (Qrr)?
No - the TRS4E65H is a unipolar SiC Schottky diode and exhibits no minority-carrier storage; therefore, its reverse recovery charge (Qrr) is effectively zero. The datasheet specifies total capacitive charge (Qc = 12 nC typ. at VR = 400 V), which governs turn-off energy loss. This absence of Qrr eliminates switching spikes and EMI associated with Si fast recovery diodes in hard-switched topologies.
What is the thermal resistance from junction to case (Rth(j-c)) for the TRS4E65H?
The TRS4E65H has a maximum thermal resistance of 2.50 °C/W from junction to case (Rth(j-c)), measured under standard mounting conditions (Note 1, Tc = 25 °C). This value enables accurate junction temperature estimation when the case temperature is monitored, supporting thermal design validation for convection- or forced-air-cooled power supplies without requiring complex simulation.
Is the TRS4E65H RoHS compliant?
Yes - the TRS4E65H is marked [[G]]/RoHS COMPATIBLE per Toshiba's documentation, confirming compliance with Directive 2011/65/EU. Lead-free soldering is supported, and the device meets JEDEC J-STD-020 moisture sensitivity level (MSL) requirements for standard reflow profiles. Full environmental compliance data, including substance declarations, is available via Toshiba's official product page or authorized distributor portals.
What is the recommended mounting torque for the TRS4E65H TO-220-2L package?
The recommended mounting torque for the TRS4E65H TO-220-2L package is 0.6 N·m, as specified in the Absolute Maximum Ratings table. Exceeding this torque risks mechanical damage to the lead frame or internal die attach, while insufficient torque degrades thermal transfer from the cathode tab to the heatsink. Use a calibrated torque screwdriver and follow Toshiba's mechanical installation guidelines to ensure reliable long-term thermal performance.
