Product details
Overview
HT16G A1G from Taiwan Semiconductor is a 600V, 1A glass-passivated high-efficiency rectifier diode in TS-1 package, featuring 1.7V forward voltage at 1A/25°C, 75ns reverse recovery time, and 30A surge capability - used in freewheeling paths of automotive DC-DC converters.
For engineers reviewing the HT16G A1G datasheet, HT16G A1G pinout, HT16G A1G application, or HT16G A1G equivalent, this page delivers verified electrical specs, thermal resistance (95°C/W), junction capacitance (10pF), AEC-Q101 qualification status, and real-world use context for power conversion design validation.
Technical Context
This device is a single-die, standard recovery silicon rectifier optimized for switching-mode power supplies. Its 600V repetitive peak reverse voltage (VRRM) and 420V RMS reverse voltage support robust operation in 48V–400V bus systems.
The 75ns reverse recovery time and 10pF junction capacitance at 1MHz/4V indicate fast switching behavior suitable for medium-frequency (<100kHz) converters. Thermal resistance of 95°C/W reflects TS-1 package limitations under natural convection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports 48V–400V input DC-DC stages with safety margin |
| IF | 1 A continuous - rated for steady-state output rectification in sub-10W converters |
| IFSM | 30 A (8.3ms half-sine) - handles startup surges and transient overloads |
| VF @ 1A/25°C | 1.7 V - contributes ~1.7W conduction loss at full load, requiring thermal derating above 75°C |
| trr | 75 ns - enables stable operation up to ~100kHz switching without excessive switching loss |
| RθJA | 95 °C/W - limits usable power dissipation to ~0.63W at 75°C ambient without heatsinking |
| CJ @ 1MHz/4V | 10 pF - minimizes capacitive coupling noise in high-dv/dt gate-drive or sensing circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R06 | 600V, 1A, VF = 1.7V, trr = 65ns, TO-220AC package | Larger footprint, higher thermal mass; requires heatsink above 0.4A continuous | Preferred where board space allows and higher surge robustness is needed |
| MBR160 | 60V, 1A Schottky, VF = 0.75V, trr = not applicable, DO-41 | Lower VRRM limits use to ≤48V systems; no reverse recovery loss but inadequate for 600V bus | Only viable in low-voltage DC-DC; not a drop-in replacement for HT16G A1G |
Compared with STTH1R06 and MBR160, HT16G A1G offers TS-1 compactness and AEC-Q101-ready variants while balancing VF, trr, and VRRM for cost-sensitive 48–400V industrial and automotive converters - unlike the Schottky MBR160, it sustains 600V blocking; unlike the TO-220 STTH1R06, it avoids heatsink dependency below 0.6A.

FAQ
What is the maximum junction temperature rating for HT16G A1G?
The HT16G A1G has a maximum junction temperature (TJ MAX) of +150°C, validated per AEC-Q101 stress testing. This rating allows operation in under-hood automotive environments and enclosed industrial enclosures. Derating begins above 75°C ambient due to its 95°C/W thermal resistance. The HT16G A1G must be mounted on PCB copper area ≥25mm² to maintain safe TJ under 1A continuous load.
Is HT16G A1G AEC-Q101 qualified?
No - HT16G A1G is the standard industrial version. AEC-Q101 qualification applies only to the HT16GH variant (marked with "H" suffix). The HT16G A1G shares identical electrical and thermal specs with HT16GH but lacks the extended reliability test report required for automotive use. For automotive applications, specify HT16GH or confirm qualification status via TSC's official documentation before design-in.
What does the "A1G" suffix mean in HT16G A1G?
The "A1G" suffix indicates tape-and-reel packaging: "A" denotes ammo box or tape-and-reel format per ordering code convention, and "1G" specifies green (halogen-free) molding compound compliant with IEC 61249-2-21. It does not denote voltage grade (that is fixed by "16" = 600V) or qualification level. The base device remains HT16G - a 600V, 1A TS-1 rectifier.
Can HT16G A1G replace HT15G in an existing design?
Yes, HT16G A1G can replace HT15G if the design requires higher reverse voltage margin: HT15G is rated at 400V VRRM, while HT16G A1G is rated at 600V. Both share identical IF (1A), IFSM (30A), VF (1.3V for HT15G vs. 1.7V for HT16G), and TS-1 package. The higher VF increases conduction loss slightly, but improves system robustness against voltage transients - verify thermal performance under worst-case load conditions.
What is the reverse leakage current specification for HT16G A1G at 125°C?
At TJ = 125°C and rated VR (600V), the HT16G A1G exhibits a maximum reverse leakage current (IR) of 150 µA, per the electrical specifications table. This value is measured using a 30ms pulse test and reflects typical stress conditions in hot automotive or industrial environments. At 25°C, IR is limited to 5 µA - critical for low-power standby modes where leakage impacts quiescent current.
