Product details

Overview

ES1C R3G from Taiwan Semiconductor is a 1 A, 150 V super fast recovery surface-mount rectifier in DO-214AC (SMA) package, featuring 35 ns reverse recovery time, 0.95 V forward voltage at 1 A, and 5 µA reverse leakage at 25°C, used in DC-DC converters and snubber circuits.

For engineers reviewing the ES1C R3G datasheet, ES1C R3G pinout, ES1C R3G application, or ES1C R3G equivalent, key selection criteria include V_RRM = 150 V, I_F = 1 A, t_rr = 35 ns, V_F = 0.95 V, and DO-214AC thermal performance (R_θJA = 85 °C/W).

Technical Context

This single-die silicon rectifier uses glass-passivated junction technology to achieve super-fast switching with low forward conduction loss and minimal reverse recovery charge. Its 35 ns t_rr enables high-frequency operation in SMPS topologies without excessive switching loss.

The device operates across -55°C to +150°C junction temperature range, supports 30 A non-repetitive surge current (8.3 ms half-sine), and exhibits 16 pF junction capacitance at 1 MHz and 4 V reverse bias - critical for EMI-sensitive snubber and freewheeling designs.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	150 V - maximum repetitive reverse voltage; defines safe blocking capability in 12–48 V DC-DC output stages
I_F	1 A continuous - rated average forward current; supports compact layout in space-constrained power modules
t_rr	35 ns - ultra-fast recovery time; reduces switching losses and improves efficiency above 100 kHz
V_F	0.95 V @ 1 A, 25°C - low forward drop; minimizes conduction loss and thermal rise in high-duty-cycle operation
I_R	5 µA @ 150 V, 25°C - low leakage ensures stable hold-off in standby and light-load conditions
R_θJA	85 °C/W - junction-to-ambient thermal resistance; determines heatsinking requirement on standard FR-4 PCB

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
ON Semiconductor MUR115	V_RRM = 150 V, t_rr = 35 ns, V_F = 0.93 V @ 1 A - nearly identical electrical specs; DO-41 through-hole package	Requires PCB redesign for through-hole mounting; not suitable for fully SMT production lines	Select when legacy through-hole assembly is mandated or thermal mass of leaded package is preferred for surge handling
Vishay VS-1EWH01-M3/5AT	V_RRM = 100 V, t_rr = 25 ns, V_F = 0.92 V @ 1 A - faster recovery but lower voltage rating; SMA package	Limited to ≤100 V systems; unsuitable for 150 V-rated bus or transient-tolerant designs	Choose only if system max reverse voltage stays below 100 V and sub-30 ns t_rr is required for >500 kHz operation

Compared with MUR115 and VS-1EWH01-M3/5AT, ES1C R3G uniquely balances 150 V blocking, 35 ns speed, and DO-214AC SMT compatibility - making it optimal for new 12–48 V industrial DC-DC designs requiring automated assembly and thermal margin.

FAQ

What is the maximum junction temperature rating for ES1C R3G?

The ES1C R3G has a maximum junction temperature (T_J) of +150°C and a minimum of –55°C. This wide operating range allows reliable use in industrial environments where ambient temperatures exceed 70°C. The device's thermal resistance (R_θJA = 85 °C/W) means that at 1 A DC forward current and typical PCB copper area, junction temperature rise remains within safe limits. Always verify thermal design using actual board layout and airflow conditions for the ES1C R3G.

Does ES1C R3G support lead-free reflow soldering?

Yes, ES1C R3G features matte tin-plated leads compliant with J-STD-002 for solderability and is rated for lead-free reflow profiles per J-STD-020 Level 1 (unlimited floor life). Its DO-214AC package withstands peak reflow temperatures up to 260°C for 10 seconds. Taiwan Semiconductor qualifies the ES1C R3G for standard Pb-free SAC305 processes without delamination or voiding - confirmed in the official ES1A–ES1J O2112 datasheet revision.

What is the reverse recovery time test condition for ES1C R3G?

The reverse recovery time (t_rr) of 35 ns for ES1C R3G is measured under the condition: I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 A, with specified pulse waveform per JEDEC standards. This reflects real-world switching behavior in hard-commutated topologies like flyback and forward converters. The value is guaranteed maximum - typical units measure ≤28 ns. Refer to Figure 6 in the ES1A–ES1J datasheet for the exact test circuit diagram applicable to ES1C R3G.

Is ES1C R3G suitable for automotive applications?

No, ES1C R3G is not qualified for automotive applications. Taiwan Semiconductor explicitly states in the ES1A–ES1J datasheet (Version O2112, Page 7) that these products "are not designed for use in medical, life-saving, or life-sustaining applications" and do not meet AEC-Q101 requirements. For automotive-grade alternatives, consider TSC's AEC-Q101-qualified rectifier families or consult Aetrix's automotive discrete portfolio for ES1C R3G-equivalent qualified parts.

How does the marking code 'ES1C' relate to the full part number ES1C R3G?

The marking code 'ES1C' on the device body identifies the voltage grade (150 V V_RRM) within the ES1x family; 'R3G' is Taiwan Semiconductor's date/batch code ('R3' = 2023 Week 3, 'G' = factory code), not an electrical variant. All ES1C-marked units - including ES1C R3G - share identical electrical specifications, DO-214AC packaging, and thermal performance per the ES1A–ES1J datasheet. No functional differentiation exists between ES1C R3G and other ES1C-lot codes.
