Product details

Overview

ES2BA R3G from Taiwan Semiconductor is a 2A, 100V 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 - deployed in DC-DC converters and snubber circuits for high-efficiency power conversion.

For engineers reviewing the ES2BA R3G datasheet, ES2BA R3G pinout, ES2BA R3G application, or ES2BA R3G equivalent, key selection criteria include V_RRM = 100V, I_F = 2A, t_rr = 35ns, thermal resistance R_θJA = 75°C/W, and DO-214AC mechanical 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 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 super-fast switching with t_rr ≤ 35ns under IF = 0.5A / IR = 1.0A / I_rr = 0.25A test conditions, enabling reduced switching losses in high-frequency SMPS topologies. Reverse leakage remains ≤10µA at 25°C and ≤350µA at 125°C under rated V_R.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	100 V - Maximum repetitive reverse voltage; defines safe blocking capability in flyback or freewheeling paths
I_F	2 A - Continuous average forward current; sets thermal design baseline for heatsinking and trace width
t_rr	35 ns - Reverse recovery time; enables operation up to ~3 MHz switching frequencies with minimal loss
V_F	0.95 V @ 2A, 25°C - Forward voltage drop; determines conduction loss and thermal load at full rated current
R_θJA	75 °C/W - Junction-to-ambient thermal resistance; used to calculate max ambient temperature for 150°C T_J limit
I_FSM	50 A - Non-repetitive peak surge current; withstands inrush or fault transients without failure
C_J	25 pF @ 1MHz, 4V - Junction capacitance; impacts high-frequency noise coupling and EMI filter design

Equivalent & Alternatives

The following parts are listed as comparable options for similar super fast rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH2R01	V_RRM = 100V, t_rr = 25ns, V_F = 0.97V @ 2A - slightly faster but higher V_F	Better suited for ultra-high-frequency (>1 MHz) resonant converters where Q_rr dominates loss	Select STTH2R01 when minimizing reverse recovery charge is critical and board space permits alternate footprint verification
MBR2100CT	Dual common-cathode Schottky, V_F = 0.82V @ 2A, no recovery time - but V_RRM = 100V, limited to ≤125°C operation	Preferred in low-voltage, high-efficiency 12V/24V systems where thermal margin is constrained	Choose MBR2100CT only if junction temperature stays below 125°C and reverse leakage tolerance allows Schottky behavior

Compared with STTH2R01 and MBR2100CT, the ES2BA R3G offers balanced trade-offs: lower cost than STTH2R01, wider temperature range than MBR2100CT, and proven reliability in industrial-grade DC-DC and lighting applications requiring 100V blocking and 2A average current.

FAQ

What is the maximum junction temperature rating for ES2BA R3G?

The ES2BA R3G has a maximum junction temperature (T_J) rating of +150°C, with a storage temperature range of -55°C to +150°C. This rating allows reliable operation in industrial environments where ambient temperatures exceed 85°C, provided thermal design maintains junction temperature within limit using R_θJA = 75°C/W and appropriate PCB copper area. The ES2BA R3G must not be operated beyond this absolute maximum.

Does ES2BA R3G have a RoHS-compliant and halogen-free construction?

Yes, the ES2BA R3G is RoHS compliant and halogen-free per IEC 61249-2-21. Its molding compound meets UL 94V-0 flammability rating, and terminals are matte tin plated per J-STD-002. These attributes ensure compliance with EU WEEE, China RoHS, and JEDEC standards - critical for export-oriented industrial and lighting products. The ES2BA R3G documentation confirms full material declaration alignment.

What is the reverse recovery time (t_rr) specification for ES2BA R3G and under what test conditions?

The ES2BA R3G reverse recovery time is specified as ≤35 ns under test conditions of I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A, per the manufacturer's electrical specifications table. This value is measured at T_A = 25°C and reflects the device's super-fast switching capability. The ES2BA R3G achieves this performance via optimized silicon doping and passivation, enabling high-frequency SMPS use without external snubbers.

Can ES2BA R3G replace ES2AA in an existing design?

No - ES2BA R3G (100V V_RRM) is not a direct replacement for ES2AA (50V V_RRM). While both share identical package, pinout, and thermal specs, the higher blocking voltage of ES2BA R3G does not guarantee safe operation at 50V-rated stress margins, especially under transient overvoltage. Redesign validation is required. The ES2BA R3G should only replace ES2AA if the application's peak reverse voltage exceeds 50V and ≤100V.

What is the moisture sensitivity level (MSL) for ES2BA R3G and how does it affect handling?

The ES2BA R3G has a moisture sensitivity level (MSL) of Level 1 per J-STD-020, meaning it may be stored indefinitely at ≤30°C/85% RH without baking prior to reflow. This eliminates pre-assembly bake cycles, reduces floor life concerns, and simplifies SMT line integration. The ES2BA R3G's Level 1 rating is confirmed in its mechanical data section and applies to the DO-214AC package construction.
