Product details
Overview
ES3CB from Taiwan Semiconductor is a 3A, 150V super fast surface-mount rectifier in DO-214AA (SMB) package, featuring 35ns reverse recovery time, 0.86V forward voltage at 3A/25°C, and 100A surge capability - deployed in high-frequency SMPS secondary-side rectification.
For engineers reviewing the ES3CB datasheet, ES3CB pinout, ES3CB application, or ES3CB equivalent, key selection criteria include VRRM=150V, IF=3A, trr≤35ns, thermal resistance RθJA=84°C/W, and SMB package compatibility with automated SMT assembly.
Technical Context
This single-die silicon rectifier uses glass-passivated junction technology to achieve stable performance across -55°C to +150°C junction temperature range. Its super-fast recovery enables efficient operation in switching frequencies up to several hundred kHz.
The device exhibits low forward voltage drop (0.73V at 3A/125°C) and minimal junction capacitance (46pF at 4V), supporting reduced conduction loss and minimized switching noise in compact power converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum repetitive reverse voltage before breakdown; sets safe operating limit in 12–48V output SMPS designs. |
| IF | 3 A - Continuous average forward current; supports 36W–72W output stages with appropriate heatsinking. |
| trr | 35 ns - Reverse recovery time; enables high-frequency operation with low switching loss in <500kHz converters. |
| VF @ 3A, 25°C | 0.86 V - Forward voltage drop; determines conduction loss of ~2.6W at full load, critical for thermal design. |
| RθJA | 84 °C/W - Junction-to-ambient thermal resistance on 10mm×10mm Cu pad; defines required PCB copper area for TJ ≤150°C. |
| CJ @ 1MHz, 4V | 46 pF - Junction capacitance; influences EMI generation and snubber sizing in flyback and LLC topologies. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S (STMicroelectronics) | VRRM=60V, trr=30ns, VF=0.85V @3A - lower voltage rating, slightly faster recovery. | Best suited for ≤60V output rails; not rated for 150V reverse stress in universal-input SMPS. | Select when VRRM margin >2× output voltage and trr priority exceeds voltage headroom. |
| SB3150 (ON Semiconductor) | VRRM=150V, trr=35ns, VF=0.92V @3A - identical VRRM and trr, but higher forward drop. | Acceptable where thermal budget allows +0.06V VF penalty; same SMB footprint and polarity marking. | Choose if supply chain diversification is needed and 0.06V higher conduction loss is tolerable. |
Compared with STTH3L06S and SB3150, ES3CB delivers optimal balance of 150V rating, 35ns recovery, and 0.86V forward drop in SMB package - making it preferred for cost-sensitive, space-constrained 12–48V SMPS where both voltage margin and efficiency matter.

FAQ
What is the maximum junction temperature rating for ES3CB?
The ES3CB has a maximum junction temperature (TJ) rating of +150°C, with operational range from -55°C to +150°C. This rating is validated under specified thermal conditions using a 10mm × 10mm copper pad test board. Derating curves in the ES3AB–ES3JB datasheet confirm usable current capacity down to 1.8A at 125°C ambient, ensuring robustness in enclosed power supplies where ES3CB operates.
Is ES3CB RoHS and halogen-free compliant?
Yes, ES3CB 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. These qualifications are explicitly stated in the mechanical data and features sections of the official Taiwan Semiconductor ES3AB–ES3JB datasheet (Version C2102).
What is the reverse recovery time (trr) of ES3CB and how is it measured?
The ES3CB reverse recovery time is rated at ≤35ns, measured under conditions of IF = 0.5A, IR = 1.0A, and Irr = 0.25A. This value is confirmed in the Electrical Specifications table of the ES3AB–ES3JB datasheet and applies across the full temperature range. The measurement method follows industry-standard double-pulse testing, enabling accurate prediction of switching loss in high-frequency converters where ES3CB is deployed.
Does ES3CB have a defined moisture sensitivity level (MSL)?
Yes, ES3CB has a moisture sensitivity level (MSL) of Level 1 per J-STD-020, meaning it is not moisture-sensitive and may be stored indefinitely at ambient conditions without baking prior to reflow. This MSL rating is explicitly listed in the FEATURES section of the ES3AB–ES3JB datasheet and simplifies handling in high-volume SMT manufacturing environments using ES3CB.
What is the marking code printed on the ES3CB device body?
The marking code printed on the ES3CB device body is "ES3CB", as confirmed in the Marking Diagram and Absolute Maximum Ratings table of the ES3AB–ES3JB datasheet. This unambiguous marking distinguishes it from other variants in the family (e.g., ES3AB, ES3DB) and ensures traceability during inspection and assembly verification of ES3CB units.
