Product details
Overview
ES3DB-13-F from Diodes Incorporated is a 200 V, 3.0 A surface-mount super-fast rectifier diode in SMC package, featuring 25 ns reverse recovery time, 0.9 V forward voltage at 3.0 A, and 100 A non-repetitive surge rating-designed for high-frequency switching power supplies and DC/DC converters.
For engineers reviewing the ES3DB-13-F datasheet, ES3DB-13-F pinout, ES3DB-13-F application, or ES3DB-13-F equivalent, this device serves as a critical output rectifier where low conduction loss, fast recovery, and robust surge handling are required in compact industrial and automotive power designs.
Technical Context
This super-fast rectifier employs glass-passivated die construction to ensure stable junction performance under thermal cycling and high dv/dt conditions. Its 25 ns reverse recovery time (measured at IF = 0.5 A, IR = 1.0 A, IRR = 0.25 A) minimizes switching losses in 100–500 kHz SMPS topologies.
The device operates across –55 °C to +150 °C with RθJA = 50 °C/W (on 5.0 mm² copper pad) and RθJT = 10 °C/W, enabling reliable thermal management in space-constrained PCB layouts without active cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Repetitive Reverse Voltage | 200 V - supports 170 VAC input rectification with safety margin in offline SMPS |
| Average Rectified Output Current | 3.0 A @ TT = +100 °C - continuous DC output capability in thermally managed designs |
| Forward Voltage | 0.9 V @ 3.0 A - reduces conduction loss to ≤2.7 W at full load |
| Reverse Recovery Time | 25 ns - limits turn-off switching loss and EMI generation in high-frequency converters |
| Surge Current Rating | 100 A (8.3 ms half-sine) - withstands inrush and transient overloads without failure |
| Junction-to-Ambient Thermal Resistance | 50 °C/W - requires ≥5 mm² copper pour for safe operation at full current |
| Operating Temperature Range | –55 °C to +150 °C - qualified for under-hood automotive and industrial ambient environments |
Pinout & Package
ES3DB-13-F uses the SMC (DO-214AB) surface-mount package: molded plastic case (UL 94V-0), cathode band polarity marking, matte tin-plated terminals, and moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input terminal for forward conduction path | Connected to transformer secondary or switch node; must handle peak surge current |
| Cathode | Output terminal for forward conduction path | Connected to output filter capacitor; polarity marking ensures correct PCB orientation |

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 | 600 V VRRM, 3.0 A IO, 50 ns tRR, TO-277 package | Higher voltage rating but slower recovery; larger footprint | Select when system requires >300 V blocking with moderate frequency (<100 kHz) |
| MBR3200FCT | 200 V VRRM, 3.0 A IO, Schottky structure, 0.55 V VF, no reverse recovery | No reverse recovery loss, but higher IR (100 µA @ 125 °C) limits high-temp use | Select for <100 °C ambient applications prioritizing lowest conduction loss |
Compared with STTH3L06S and MBR3200FCT, ES3DB-13-F uniquely balances 200 V rating, 25 ns speed, and 150 °C operation-making it optimal for compact, high-efficiency 200–300 kHz industrial and automotive SMPS where thermal headroom and EMI control are critical.

FAQ
What is the maximum allowable junction temperature for ES3DB-13-F?
The absolute maximum junction temperature is +150 °C, with continuous operation rated up to +100 °C terminal temperature. Derating begins above +100 °C per Figure 1 in the datasheet, where average current drops linearly to zero at +150 °C. Thermal design must maintain TJ ≤ 150 °C under worst-case surge and ambient conditions.
Is ES3DB-13-F suitable for synchronous rectification circuits?
No-ES3DB-13-F is a passive super-fast rectifier diode, not a MOSFET-based synchronous rectifier. It lacks gate control and cannot be actively switched. It functions only as a unidirectional conduction device with fixed forward voltage and recovery behavior, making it appropriate for non-synchronous or quasi-synchronous topologies where simplicity and cost outweigh efficiency gains from active switching.
Does ES3DB-13-F meet AEC-Q101 qualification requirements?
ES3DB-13-F is not explicitly AEC-Q101 qualified per Diodes' public documentation. While manufactured in IATF 16949-certified facilities and compliant with RoHS 3 and halogen-free standards, formal automotive qualification requires separate PPAP submission and test reports. For AEC-Q101–compliant alternatives, contact Diodes' automotive team directly.
How does the SMC package compare to SMB in thermal performance for ES3DB-13-F?
The SMC package used in ES3DB-13-F offers lower thermal resistance than SMB: RθJA = 50 °C/W (SMC) vs. ~65 °C/W (SMB, typical), due to larger copper pad area and higher mass. This allows 3.0 A continuous current at +100 °C terminal temperature in SMC, whereas SMB variants (e.g., ES3DB-13-F's SMB counterpart ES3DB-13-F is not valid; correct SMB variant is ES3D-B-13-F) require earlier derating above +85 °C ambient.
