Product details

Overview

ES3C V7G from Taiwan Semiconductor is a 3A, 150V super fast recovery surface-mount rectifier diode in DO-214AB (SMC) package, featuring 35ns reverse recovery time, 0.95V max forward voltage at 3A/25°C, and 100A peak surge current - used for freewheeling and high-frequency rectification in switching-mode power supplies.

For engineers reviewing the ES3C V7G datasheet, ES3C V7G pinout, ES3C V7G application, or ES3C V7G equivalent, key selection criteria include V_RRM = 150V, I_F = 3A, t_rr = 35ns, thermal resistance R_θJA = 47°C/W, and DO-214AB mechanical compatibility with automated SMT assembly lines.

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 super-fast recovery enables efficient operation in DC-DC converters and offline SMPS operating above 50kHz.

The device exhibits low junction capacitance (45pF at 4V), minimal reverse leakage (≤10µA at 25°C), and meets J-STD-020 moisture sensitivity level 1 - confirming suitability for lead-free reflow without preconditioning.

Key Specifications

Parameter	Value and Actual Design Meaning

t_rr	35 ns - measured at I_F = 0.5A, I_R = 1.0A, I_rr = 0.25A; enables >100kHz switching with low switching loss
V_F (max)	0.95 V at 3A/25°C - directly impacts conduction loss and thermal rise in high-duty-cycle applications
R_θJA	47 °C/W - junction-to-ambient thermal resistance; determines required copper area and airflow for thermal management
C_J	45 pF at 1MHz/4V - limits high-frequency noise coupling and EMI in snubberless designs

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 = 30ns, V_F = 1.15V @ 3A - higher blocking, faster recovery, but higher forward drop	Suitable for 400V+ PFC stages where ES3C V7G's 150V rating is insufficient	Select STTH3L06S only if system requires >300V reverse standoff; verify thermal margin due to higher V_F
MBR3150	Schottky structure, V_F = 0.82V @ 3A, but V_RRM = 150V and I_R = 1mA @ 125°C - lower conduction loss, higher leakage	Better for low-voltage, high-efficiency DC-DC where leakage-induced standby loss is acceptable	Prefer MBR3150 in battery-powered or energy-star-compliant designs; avoid in high-temperature environments (>85°C ambient)

Compared with STTH3L06S and MBR3150, ES3C V7G delivers optimal balance of low V_F, moderate leakage, and robust surge handling in 150V-class SMPS - making it preferred for cost-sensitive telecom and industrial adapter designs where thermal headroom and reliability under repeated surge stress are prioritized over ultra-low V_F.

FAQ

What is the maximum junction temperature rating for ES3C V7G?

The ES3C V7G has a maximum junction temperature (T_JMAX) of +150°C, verified per absolute maximum ratings table in Taiwan Semiconductor's N2102 datasheet. This rating allows reliable operation in enclosed power supplies with limited airflow, provided PCB thermal design maintains junction temperature below this limit during worst-case load and ambient conditions. The ES3C V7G must not be operated beyond 150°C junction temperature to ensure long-term reliability.

Does ES3C V7G support lead-free reflow soldering?

Yes, ES3C V7G supports lead-free reflow soldering per J-STD-002 requirements. Its matte tin-plated leads and moisture sensitivity level 1 (per J-STD-020) mean no baking or special handling is needed prior to standard Pb-free reflow profiles. The DO-214AB package remains structurally stable up to 260°C peak temperature, and the ES3C V7G's internal construction tolerates thermal shock typical of modern SMT assembly lines.

What is the reverse recovery time (t_rr) specification for ES3C V7G?

The reverse recovery time (t_rr) for ES3C V7G is specified as 35ns maximum, measured under conditions of I_F = 0.5A, I_R = 1.0A, and I_rr = 0.25A. This value is confirmed in the Electrical Specifications table of the N2102 datasheet and applies directly to the ES3C V7G variant. It enables efficient operation in switching converters operating up to 200kHz without significant switching loss penalties.

Is ES3C V7G pin-compatible with other ES3x series devices?

Yes, ES3C V7G shares identical DO-214AB (SMC) package dimensions and anode/cathode terminal configuration with all ES3x family members (ES3A–ES3J). Mechanical compatibility is confirmed in the Package Outline Dimensions section of the N2102 datasheet. However, electrical parameters - especially V_RRM, V_F, and C_J - differ across variants, so substitution requires verification against circuit voltage and loss requirements.

What does the 'V7G' suffix indicate in ES3C V7G?

The 'V7G' suffix in ES3C V7G denotes Taiwan Semiconductor's internal manufacturing code: 'V7' identifies the wafer lot and process revision, while 'G' indicates green (halogen-free) molding compound per IEC 61249-2-21. This marking aligns with the "G = Green Compound" notation in the Marking Diagram section of the N2102 datasheet and confirms full RoHS and halogen-free compliance for the ES3C V7G unit.
