Product details

Overview

ESH3C V7G from Taiwan Semiconductor is a 150V ultra-fast recovery surface-mount rectifier diode in DO-214AB (SMC) package, rated for 3A average forward current, 125A non-repetitive surge, and 20ns reverse recovery time - deployed in high-frequency switching mode power supplies for telecom and computing infrastructure.

For engineers reviewing the ESH3C V7G datasheet, ESH3C V7G pinout, ESH3C V7G application, or ESH3C V7G equivalent, key selection criteria include its 150V V_RRM, 0.9V max forward voltage at 3A, 5µA max reverse leakage at 25°C, DO-214AB mechanical compatibility, and ultra-fast 20ns trr performance in compact SMC footprint.

Technical Context

The ESH3C V7G is a single-die, glass-passivated silicon junction rectifier optimized for high-efficiency DC/DC conversion where fast switching and low conduction loss are critical. Its 20ns reverse recovery time and 45pF junction capacitance support operation up to several hundred kHz in SMPS freewheeling and output rectification stages.

Thermally, it features 12°C/W junction-to-lead resistance and operates across –55°C to +175°C junction temperature range. The matte tin-plated leads meet J-STD-002 solderability and JESD201 Class 2 whisker resistance requirements.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	150 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in flyback/freewheeling circuits
I_F	3 A - Continuous average forward current at T_L = 75°C; determines thermal design margin in PCB layout
t_rr	20 ns - Measured at I_F = 0.5A, I_R = 1.0A, I_rr = 0.25A; enables high-frequency switching with minimal switching loss
V_F (max)	0.9 V @ 3A, 25°C - Directly impacts conduction loss and thermal rise in high-current output rails
I_R (max)	5 µA @ 25°C, 150V - Low leakage preserves efficiency in standby and light-load conditions
R_θJL	12 °C/W - Enables direct thermal coupling to copper pour or heatsink pad for reliable 3A operation

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH3L06S	600V V_RRM, 3A I_F, 35ns t_rr, same DO-214AB package	Higher voltage rating but slower recovery; suited for PFC front-end, not secondary-side SMPS	Select when system requires >200V blocking with moderate speed; avoid where <25ns t_rr is critical for efficiency
ON Semi MUR315	150V V_RRM, 3A I_F, 35ns t_rr, DO-214AB package, higher V_F (1.15V)	Same voltage class but higher conduction loss and slower recovery; less efficient at high frequency	Acceptable for cost-sensitive designs below 100kHz; not recommended for >200kHz telecom or server applications

Compared with STTH3L06S and MUR315, the ESH3C V7G delivers superior high-frequency efficiency due to its 20ns t_rr and 0.9V V_F, making it optimal for dense, thermally constrained telecom and server power stages where switching loss dominates total loss.

FAQ

What is the maximum junction temperature rating for the ESH3C V7G?

The ESH3C V7G has a maximum junction temperature (T_J) of +175°C and a minimum of –55°C. This wide operating range allows reliable deployment in sealed industrial enclosures and high-ambient environments. Thermal design must ensure R_θJL = 12°C/W is leveraged via proper PCB copper mass or heatsinking to maintain ESH3C V7G junction temperature within limits under 3A continuous load.

Does the ESH3C V7G have a halogen-free construction?

Yes, the ESH3C V7G uses halogen-free molding compound compliant with IEC 61249-2-21. This satisfies environmental compliance requirements for green electronics manufacturing and supports end-of-life recycling protocols. The halogen-free status applies to the entire device including encapsulant and leadframe, and is verified per TSC's material declarations for ESH3x series.

What does the 'V7G' suffix indicate in ESH3C V7G?

The 'V7G' suffix denotes Taiwan Semiconductor's internal date code and environmental marking: 'V7' corresponds to 2027 Week 7 production batch, and 'G' indicates green (halogen-free) compound per IEC 61249-2-21. It does not affect electrical specifications - all ESH3C devices share identical V_RRM = 150V, t_rr = 20ns, and I_F = 3A ratings regardless of suffix.

Is the ESH3C V7G suitable for use in automotive applications?

No, the ESH3C V7G is not qualified for automotive applications. Taiwan Semiconductor explicitly states that ESH3x devices are not designed for medical, life-saving, or life-sustaining systems - including automotive ADAS or powertrain functions. For automotive-grade alternatives, consult TSC's AEC-Q101-qualified rectifier portfolio; ESH3C V7G remains intended for industrial, telecom, and computing power supplies.

How is the cathode identified on the ESH3C V7G package?

The cathode of the ESH3C V7G is marked by a distinct color band printed on the body of the DO-214AB (SMC) package. Per mechanical drawing and JEDEC standards, this band aligns with the cathode terminal - the lead opposite the banded end is the anode. Correct orientation is essential to prevent reverse breakdown; PCB silkscreen must match the band position shown in TSC's marking diagram for ESH3C V7G.
