Product details

Overview

ES3DBHR5G from Taiwan Semiconductor is a 3A, 200V super fast recovery surface-mount rectifier in DO-214AA (SMB) package, featuring 35ns reverse recovery time, 0.86V forward voltage at 3A/25°C, and 100A surge current capability; used in high-efficiency SMPS secondary-side rectification.

For engineers reviewing the ES3DBHR5G datasheet, ES3DBHR5G pinout, ES3DBHR5G application, or ES3DBHR5G equivalent, key selection criteria include V_RRM=200V, I_F=3A, t_rr≤35ns, thermal resistance R_θJA=84°C/W, and SMB package compatibility with automated SMT assembly.

Technical Context

This discrete silicon rectifier uses a glass-passivated PN junction optimized for high-frequency switching operation. Its super-fast recovery (t_rr ≤35ns) minimizes switching losses in DC-DC converters and offline SMPS topologies operating above 50kHz.

The device supports continuous forward current up to 3A at 150°C junction temperature and withstands 100A non-repetitive surge current (8.3ms half-sine). Thermal performance is characterized with R_θJL=24°C/W and R_θJC=26°C/W on standard 10mm×10mm PCB copper pads.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - Maximum repetitive reverse voltage; defines safe blocking capability in 200V-rated power rails.
I_F	3 A - Continuous average forward current; supports output stages delivering up to ~36W at 12V with adequate heatsinking.
t_rr	35 ns - Reverse recovery time; enables efficient operation in 100–500 kHz SMPS without excessive diode switching loss.
V_F @ 3A, 25°C	0.86 V - Forward voltage drop; contributes ~2.6W conduction loss at full load, requiring thermal management.
R_θJA	84 °C/W - Junction-to-ambient thermal resistance; determines required PCB copper area for T_J ≤150°C at 3A.
I_FSM	100 A - Non-repetitive peak forward surge current; handles inrush and transient overloads in adapter and lighting applications.

Pinout & Package

DO-214AA (SMB) surface-mount package with cathode band marking; 2-terminal unidirectional configuration. Matte tin-plated leads meet J-STD-002 solderability and JESD201 Class 2 whisker resistance.

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	V_RRM=600V, t_rr=35ns, V_F=0.95V@3A, DO-214AA	Higher blocking voltage; higher V_F increases conduction loss in 200V systems	Select when system requires >200V reverse margin or operates with elevated input transients.
ON Semi MUR320	V_RRM=200V, t_rr=35ns, V_F=0.93V@3A, DO-214AA	Nearly identical ratings; slightly higher V_F and same thermal resistance	Drop-in alternative where Taiwan Semiconductor supply continuity is constrained; verify marking and lot traceability.

Compared with STTH3L06S and MUR320, ES3DBHR5G offers the lowest forward voltage (0.86V) among 200V-class 3A super-fast rectifiers in SMB, directly reducing conduction loss and PCB heating in thermally dense adapter and lighting designs.

FAQ

What is the maximum junction temperature rating for ES3DBHR5G?

The ES3DBHR5G has a maximum junction temperature (T_J) rating of +150°C, verified per absolute maximum ratings table. This allows reliable operation in enclosed adapters and LED drivers where ambient temperatures reach 85°C, provided PCB thermal design maintains junction rise within limits using the specified R_θJA=84°C/W value.

Does ES3DBHR5G have a halogen-free construction?

Yes, ES3DBHR5G is halogen-free in accordance with IEC 61249-2-21 and RoHS-compliant. The molding compound contains no brominated or chlorinated flame retardants, making it suitable for environmentally regulated consumer and industrial end equipment.

What is the reverse recovery time specification for ES3DBHR5G?

The reverse recovery time (t_rr) for ES3DBHR5G is specified as ≤35ns under test conditions of I_F=0.5A, I_R=1.0A, and I_RR=0.25A. This value is measured per JEDEC standards and confirmed across production lots for consistent high-frequency switching behavior.

Is ES3DBHR5G suitable for use in automotive applications?

No, ES3DBHR5G is not qualified for automotive applications. Taiwan Semiconductor explicitly states that products in the ES3x family are not designed for medical, life-saving, or life-sustaining applications-including automotive safety-critical systems-and lack AEC-Q101 qualification.

What does the 'HR5G' suffix indicate in ES3DBHR5G?

The 'HR5G' suffix in ES3DBHR5G denotes Taiwan Semiconductor's internal tape-and-reel packaging code: 'H' = halogen-free, 'R5' = 3,000-piece reel, 'G' = green compound. It does not affect electrical specifications-the device remains functionally identical to ES3DB in DO-214AA.
