Product details
Overview
ES2CAHR3G 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 forward voltage at 2A/25°C, and 50A peak surge current - used in DC-DC converters and snubber circuits.
For engineers reviewing the ES2CAHR3G datasheet, ES2CAHR3G pinout, ES2CAHR3G application, or ES2CAHR3G 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 35ns reverse recovery for efficient high-frequency switching.
The device operates with 10µA max reverse leakage at 25°C and 350µA at 125°C under rated VR, and exhibits 25pF junction capacitance at 1MHz/4V - enabling predictable behavior in snubber and freewheeling paths where capacitive loading affects transient response.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - maximum repetitive reverse voltage the device blocks without breakdown in normal operation |
| IF | 2 A - continuous average forward current rating at 75°C lead temperature |
| trr | 35 ns - reverse recovery time measured at IF = 0.5A, IR = 1.0A, Irr = 0.25A; critical for minimizing switching losses in SMPS |
| VF | 0.95 V max at IF = 2A, TJ = 25°C - directly impacts conduction loss and thermal rise in power path |
| RθJA | 75 °C/W - junction-to-ambient thermal resistance; determines required heatsinking or board copper area for thermal management |
| IFSM | 50 A - non-repetitive peak forward surge current for 8.3ms half-sine wave; defines short-circuit withstand capability |
Pinout & Package
Package: DO-214AC (SMA), molded epoxy case with matte tin-plated leads, polarity indicated by cathode band, weight ≈ 0.060g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of load or switch node; must handle full IF and IFSM currents |
| Cathode | Forward current exit / reverse blocking terminal | Marked by band; connects to higher-potential rail; sustains full VRRM during off-state |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable long-term reliability and reduced parameter drift under thermal cycling and humidity exposure |
| Super fast recovery (35ns) | Reduces switching losses and EMI generation in 100kHz–1MHz DC-DC topologies compared to standard rectifiers |
| DO-214AC (SMA) package | Supports automated pick-and-place and reflow soldering; compatible with IPC-7351B footprint standards |
| Moisture sensitivity level 1 | Eliminates need for dry-packaging or baking prior to assembly - reduces manufacturing overhead |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R015 | VRRM = 150V, trr = 30ns, VF = 0.92V @ 2A - slightly faster but same voltage/current class | Optimized for ultra-low Qrr in high-frequency PFC stages | Preferable where <5ns trr reduction improves system efficiency at >300kHz |
| MBR2150CT | Dual common-cathode Schottky; VF = 0.82V @ 2A, zero recovery time, but VRRM = 150V max and leakage >100µA @ 125°C | Suitable for low-noise, low-VF applications where reverse leakage is acceptable | Choose only if system thermal design accommodates higher IR and layout allows dual-diode footprint |
Compared with STTH2R015 and MBR2150CT, ES2CAHR3G offers balanced trade-offs: lower cost than STTH2R015, better high-temperature leakage than MBR2150CT, and proven robustness in industrial snubber and freewheeling roles per Taiwan Semiconductor's qualification data.

FAQ
What is the maximum junction temperature rating for ES2CAHR3G?
The ES2CAHR3G has a maximum junction temperature (TJ) rating of +150°C, with a storage temperature range of -55°C to +150°C. This rating enables reliable operation in industrial environments where ambient temperatures exceed 85°C, provided thermal design maintains junction temperature within limit using the specified RθJA = 75°C/W and appropriate PCB copper area.
Does ES2CAHR3G meet RoHS and halogen-free requirements?
Yes, ES2CAHR3G is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound meets UL 94V-0 flammability rating, and terminals are matte tin plated per J-STD-002 solderability standards - confirming suitability for lead-free reflow processes and environmentally regulated end equipment.
What is the reverse recovery time test condition for ES2CAHR3G?
The reverse recovery time (trr) of 35ns for ES2CAHR3G is measured under standardized conditions: IF = 0.5A, IR = 1.0A, Irr = 0.25A, with test circuit per Figure 6 in the official datasheet. This value reflects real-world switching behavior in high-frequency power converters and is not extrapolated from other variants.
Is ES2CAHR3G pin-compatible with other ES2x series rectifiers?
Yes, all ES2x series devices including ES2CAHR3G use identical DO-214AC (SMA) package and anode/cathode pinout. Voltage ratings differ across the family (e.g., ES2AA = 50V, ES2JA = 600V), but mechanical mounting, thermal pad layout, and polarity marking remain consistent - enabling drop-in replacement within same VRRM class.
What is the typical junction capacitance of ES2CAHR3G?
The typical junction capacitance (CJ) of ES2CAHR3G is 25pF, measured at 1MHz and VR = 4.0V. This value is confirmed in the Electrical Specifications table for ES2AA–ES2DA group and directly applies to ES2CAHR3G per the family datasheet revision M2102 - influencing high-frequency noise filtering and snubber tuning calculations.
