Taiwan Semiconductor Corporation 1T5G A0G

Overview

1T5G A0G from Taiwan Semiconductor is a 600 V, 1 A standard silicon rectifier diode in TS-1 package, featuring 30 A surge capability, 1.0 V max forward voltage at 1 A and 25°C, and AEC-Q101 qualification option (H-suffix). It serves as a primary AC/DC input rectifier in compact power supplies.

For engineers reviewing the 1T5G A0G datasheet, 1T5G A0G pinout, 1T5G A0G application, or 1T5G A0G equivalent, key selection criteria include repetitive peak reverse voltage (600 V), forward current rating (1 A), thermal resistance (100 °C/W), RoHS/halogen-free compliance, and TS-1 mechanical compatibility with automated assembly.

Technical Context

This single-die standard rectifier operates with unidirectional conduction, defined by cathode-band polarity marking and pure tin-plated leads compliant with J-STD-002 solderability. Its junction-to-ambient thermal resistance of 100 °C/W enables operation up to 150 °C junction temperature under appropriate PCB copper area.

Electrical behavior is characterized by low forward voltage drop (≤1.0 V at 1 A, 25°C), low reverse leakage (≤5 µA at 25°C, ≤100 µA at 125°C), and 10 pF junction capacitance at 1 MHz and 4 V reverse bias - suitable for medium-frequency switching applications up to ~100 kHz.

Equivalent & Alternatives

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

Compared with STTH1R06U and MUR106, the 1T5G A0G offers optimal balance of TS-1 SMT compatibility, 1.0 V VF ceiling, and optional AEC-Q101 qualification - making it preferred for new compact, automotive-adjacent, or RoHS-compliant designs where footprint and reliability are prioritized over absolute minimum RθJA.

Availability

1T5G A0G is available at Aetrix Electronics and suitable for AC/DC adapters, industrial DC power supplies, and switching mode inverters requiring stable component supply, RoHS compliance, and AEC-Q101-ready variants.

Supply support for 1T5G A0G includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Taiwan Semiconductor Corporation (TSC) is a vertically integrated analog and discrete semiconductor manufacturer headquartered in Hsinchu, Taiwan, serving industrial, computing, and automotive markets since 1979.

The 1T1G–1T7G series was designed specifically for cost-sensitive, space-constrained AC/DC and DC/DC power conversion applications requiring standardized voltage grades (50–1000 V), robust surge capability, and SMT manufacturability in TS-1 form factor.

FAQ

What is the peak repetitive reverse voltage rating for the 1T5G A0G?

The 1T5G A0G has a peak repetitive reverse voltage (VRRM) rating of 600 V. This value is fixed per the "5" in the part number (1T1G–1T7G mapping: 1=50 V, 2=100 V, ..., 5=600 V). It defines the maximum AC or DC reverse voltage the device can block continuously without avalanche breakdown under normal operating conditions.

Is the 1T5G A0G AEC-Q101 qualified?

No - the 1T5G A0G is not AEC-Q101 qualified. The "A0G" suffix indicates TS-1 packaging in ammo box (3,000 pcs), but lacks the "H" suffix required for AEC-Q101 qualification. To obtain AEC-Q101 compliance, specify 1T5GH or 1T5GHA0G, both of which undergo full automotive stress testing per JESD22 and JESD22-A114.

What does the "A0G" suffix mean in 1T5G A0G?

The "A0G" suffix in 1T5G A0G denotes packaging format: "A0" specifies ammo box packaging (3,000 units per box), and "G" indicates RoHS-compliant, halogen-free green molding compound. It does not affect electrical parameters - all 1T5G variants (A0G, tape & reel, H-suffix) share identical VRRM=600 V, IF=1 A, and VF≤1.0 V specs.

Can the 1T5G A0G replace a DO-41 rectifier like 1N4007 in a new design?

Yes - the 1T5G A0G provides equivalent 600 V blocking and 1 A current capability as the 1N4007 but in a smaller, surface-mount TS-1 package. However, thermal design differs: RθJA is 100 °C/W (vs. ~65 °C/W for DO-41 on 1"² copper), so PCB layout must allocate adequate copper area for heat dissipation when replicating 1N4007 performance.

What is the maximum junction temperature and how is it used in thermal design for the 1T5G A0G?

The 1T5G A0G has a maximum junction temperature (TJ max) of +150 °C. In thermal design, this limit is used with RθJA = 100 °C/W to calculate allowable ambient temperature rise: ΔT = TJ max − TA = (150 − TA) °C. For example, at TA = 70 °C, the junction can rise 80 °C, requiring ≤0.8 W power dissipation (P = ΔT / RθJA).
