Product details
Overview
ES2CA R3G from Taiwan Semiconductor is a 2A, 150V super fast recovery surface-mount rectifier in DO-214AC (SMA) package, featuring 35ns reverse recovery time, 0.95V max forward voltage at 2A, and 50A peak surge current - used in DC-DC converters and snubber circuits for high-efficiency power conversion.
For engineers reviewing the ES2CA R3G datasheet, ES2CA R3G pinout, ES2CA R3G application, or ES2CA R3G equivalent, key selection criteria include VRRM = 150V, IF = 2A, trr = 35ns, thermal resistance RθJA = 75°C/W, and DO-214AC mechanical compatibility with automated SMT assembly.
Technical Context
This single-die, unidirectional silicon rectifier uses glass-passivated junction technology to achieve stable performance across -55°C to +150°C junction temperature range. Its low-profile DO-214AC package supports high-density PCB layouts while maintaining J-STD-020 Level 1 moisture sensitivity and JESD 201 Class 2 whisker resistance.
The device delivers 35ns reverse recovery time under IF = 0.5A / IR = 1.0A / Irr = 0.25A test conditions, enabling efficient operation in high-frequency switching topologies. Junction capacitance is 25pF at 1MHz and 4.0V reverse bias, supporting minimal capacitive loading in snubber and freewheeling roles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - maximum repetitive reverse voltage before breakdown; defines safe operating limit in DC-DC output rectification |
| IF | 2 A - continuous average forward current; determines steady-state power handling in converter secondary side |
| trr | 35 ns - reverse recovery time; enables >100 kHz switching without excessive switching loss or ringing |
| VF (max) | 0.95 V @ 2A, 25°C - forward voltage drop; directly impacts conduction loss and thermal rise in high-duty-cycle applications |
| RθJA | 75 °C/W - junction-to-ambient thermal resistance; sets minimum heatsinking requirement for 2A continuous operation |
| IFSM | 50 A - non-repetitive peak surge current (8.3ms half-sine); withstands inrush and transient overloads in power supplies |
Pinout & Package
DO-214AC (SMA) package: molded epoxy case meeting UL 94V-0, matte tin-plated leads solderable per J-STD-002, cathode indicated by band, weight ≈0.060g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential node (e.g., transformer secondary center-tap or switch node return path) |
| Cathode | Forward current exit point | Connected to output rail or filter capacitor positive; polarity marked by visible band on body |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enhances long-term reliability and humidity resistance in industrial environments without hermetic sealing |
| Super fast recovery (35ns) | Reduces switching losses and EMI generation in high-frequency SMPS designs up to 500 kHz |
| DO-214AC (SMA) footprint | Enables direct placement on standard SMT lines with no retooling; compatible with IPC-7351B land patterns |
| J-STD-020 Level 1 moisture sensitivity | Eliminates bake requirements prior to reflow, reducing manufacturing cost and cycle time |
Applications
| DC–DC Converter Output Rectification | Snubber Circuit |
|---|---|
Use Scenario: Secondary-side rectification in isolated flyback or forward converters delivering 5–24V at up to 2A. IC Role / Device Role / Timing Role: Unidirectional current steering diode converting high-frequency AC from transformer into regulated DC output. Use Value: 0.95V VF minimizes conduction loss; 35ns trr prevents reverse recovery-induced cross-conduction in synchronous designs. | Use Scenario: RC snubber network across MOSFET drain-source or transformer primary winding. IC Role / Device Role / Timing Role: Fast-recovery clamp diode absorbing inductive kick energy during switching transitions. Use Value: 150V VRRM safely handles typical 100–120VAC-derived transients; 25pF CJ limits capacitive loading of snubber resistor. |
| Freewheeling Diode | Lighting Driver (LED Buck) |
Use Scenario: Inductor current recirculation path in non-synchronous buck or boost regulators powering industrial sensors. IC Role / Device Role / Timing Role: Freewheeling path enabling continuous inductor current during high-side switch off-time. Use Value: 50A IFSM withstands startup surges; 75°C/W RθJA allows operation at 2A without external heatsink in ambient ≤50°C. | Use Scenario: Constant-current LED driver stage in commercial downlight or streetlight modules. IC Role / Device Role / Timing Role: Output rectifier in isolated LED driver secondary, handling 2A continuous forward current. Use Value: RoHS- and halogen-free compliance meets IEC 62471 photobiological safety requirements; DO-214AC fits compact LED module footprints. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R015 | VRRM = 150V, trr = 30ns, VF = 0.92V @ 2A - slightly faster but same voltage rating | Optimized for ultra-high-frequency PFC stages; tighter trr tolerance (±5ns vs ±10ns) | Preferred where <30ns trr is required for EMI suppression below 150 MHz |
| MBR2150CT | Dual common-cathode Schottky; VF = 0.82V @ 2A, zero recovery charge - but VRRM = 150V only per diode | Used in dual-output or redundancy configurations; not suitable for single-diode freewheeling | Select when lower VF outweighs need for true fast-recovery behavior in high-dV/dt environments |
Compared with STTH2R015 and MBR2150CT, ES2CA R3G offers balanced trade-offs: sufficient speed for 100–300 kHz converters, robust 150V rating, and proven reliability in industrial-grade DO-214AC packaging - making it optimal for cost-sensitive, high-volume power supply designs requiring field-proven performance.

FAQ
What is the maximum junction temperature rating for ES2CA R3G?
The ES2CA R3G has a maximum junction temperature (TJ) of +150°C, with operational capability from -55°C to +150°C. This rating allows reliable use in enclosed industrial power supplies where ambient temperatures may reach 70–85°C, provided thermal design accounts for its 75°C/W junction-to-ambient resistance. Derating curves in the ES2AA–ES2JA datasheet confirm 2A continuous current is sustainable up to 110°C case temperature.
Is ES2CA R3G RoHS and halogen-free compliant?
Yes, ES2CA R3G is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants or chlorine-based additives, and lead content is below 1000 ppm. This compliance supports environmental requirements for export to EU, Japan, and China RoHS markets, and aligns with TSC's green manufacturing policy documented in Version M2102 of the ES2AA–ES2JA datasheet.
What does the 'R3G' suffix indicate in ES2CA R3G?
The 'R3G' suffix in ES2CA R3G denotes tape-and-reel packaging: R3 = 7,500 units per reel, G = green compound (halogen-free epoxy). This matches TSC's ordering code convention in the ES2AA–ES2JA datasheet, where 'R3' specifies reel quantity and 'G' confirms compliance with halogen-free standards - critical for automotive and industrial customers requiring material declarations.
Can ES2CA R3G replace ES2DA R3G in a 200V design?
No, ES2CA R3G is not a safe replacement for ES2DA R3G in a 200V design. ES2CA R3G has VRRM = 150V, while ES2DA R3G is rated for 200V. Exceeding 150V reverse voltage risks avalanche breakdown and premature failure. The datasheet explicitly assigns voltage grades per part number: ES2CA = 150V, ES2DA = 200V - substitution requires verification of worst-case reverse stress including transients and derating margins.
What is the reverse recovery time test condition for ES2CA R3G?
The reverse recovery time (trr) of 35ns for ES2CA R3G is measured under the condition: IF = 0.5A, IR = 1.0A, Irr = 0.25A, per the ES2AA–ES2JA datasheet. This standardized test reflects real-world switching behavior in hard-commutated topologies. The value is a maximum specification - typical trr is lower, but design margin must be based on the 35ns limit to ensure consistent EMI and efficiency performance across temperature and lot variation.
