Product details
Overview
HT16G from Taiwan Semiconductor is a 600V, 1A glass-passivated high-efficiency rectifier diode in TS-1 package, featuring 1.7V forward voltage at 1A and 75ns reverse recovery time, used in freewheeling paths of switching-mode DC-DC converters.
For engineers reviewing the HT16G datasheet, HT16G pinout, HT16G application, or HT16G equivalent, key selection criteria include peak reverse voltage (600V), surge current rating (30A), thermal resistance (95°C/W), AEC-Q101 qualification status, and TS-1 mechanical compatibility for automotive and industrial power supplies.
Technical Context
The HT16G is a single-die, silicon planar junction rectifier with glass-passivated chip construction, optimized for high-reliability freewheeling and output rectification in high-frequency switching circuits. Its 600V VRRM and 75ns trr support operation in 100–500kHz SMPS topologies.
Thermal performance is defined by RθJA = 95°C/W in free-air conditions, and the device operates across -55°C to +150°C junction temperature range. It meets JESD201 Class 2 whisker resistance and RoHS/halogen-free compliance per IEC 61249-2-21.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum repetitive reverse voltage before breakdown; sets upper limit for DC bus or clamp voltage in flyback/freewheeling designs |
| IF | 1 A - Continuous average forward current; defines steady-state conduction capability at TA = 25°C with derating above 25°C |
| IFSM | 30 A - Non-repetitive surge current (8.3ms half-sine); supports inrush and transient overload without failure |
| VF @ 1A, 25°C | 1.7 V - Forward voltage drop; directly impacts conduction loss and thermal design in high-duty-cycle applications |
| trr | 75 ns - Reverse recovery time; determines switching loss and EMI behavior in hard-switched converters >100kHz |
| RθJA | 95 °C/W - Junction-to-ambient thermal resistance; used to calculate max ambient temperature for 150°C TJ limit at 1A load |
Pinout & Package
TS-1 package: molded epoxy case with pure tin-plated leads, cathode indicated by band, UL 94V-0 rated compound, 0.200g weight, JESD201 Class 2 whisker compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential node (e.g., switch node in buck/flyback) during conduction phase |
| Cathode | Forward current exit point | Connected to higher-potential node (e.g., output rail or ground return) and marked with band |
Key Features

Applications
| DC-DC Converter Output Rectification | Switching Mode Inverter Freewheeling |
|---|---|
Use Scenario: Secondary-side rectification in isolated 12V/24V output flyback or forward converters operating at 200–300kHz. IC Role / Device Role / Timing Role: Unidirectional current path enabling energy transfer from transformer secondary to output capacitor. Use Value: 1.7V VF and 75ns trr reduce total power loss by 0.3–0.5W vs. legacy rectifiers, improving efficiency by 1.2–1.8% at full load. | Use Scenario: Freewheeling path across IGBTs or MOSFETs in motor drive inverters handling 1–5kW loads. IC Role / Device Role / Timing Role: Provides low-loss current recirculation path during switching transitions to suppress voltage spikes. Use Value: 30A IFSM withstands motor startup surges; 600V VRRM accommodates 400V DC bus with 50% safety margin. |
| Automotive HVAC Power Supply | Industrial PLC Power Input Stage |
Use Scenario: Input rectification and hold-up in 12V/24V automotive HVAC control modules requiring AEC-Q101 compliance. IC Role / Device Role / Timing Role: Converts AC input (e.g., from transformer or line-derived source) to unregulated DC for downstream regulation. Use Value: Glass passivation and AEC-Q101 qualification ensure 15-year field life under under-hood thermal cycling (-40°C to +125°C). | Use Scenario: Primary-side bridge rectification in 24V/48V industrial PLC power inputs exposed to line transients and brownouts. IC Role / Device Role / Timing Role: Handles continuous 1A load and absorbs 30A surge events from relay coil de-energization or inductive load switching.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L60S | 600V, 1A, TO-277A package, VF = 1.7V, trr = 65ns, no AEC-Q101 option | Same VRRM/IF but different footprint; requires PCB layout change | Preferred where faster trr is critical and automotive qualification not required |
| SB160-E3/54 | 60V, 1A, DO-41 package, VF = 0.7V, trr = 50ns - lower voltage rating, smaller package | Not suitable for 600V systems; limited to low-voltage DC-DC outputs | Only viable in <100V applications where low VF dominates over surge capability |
Compared with STTH1L60S and SB160-E3/54, the HT16G uniquely combines 600V rating, TS-1 surface-mount compatibility, AEC-Q101 availability, and 75ns trr-making it optimal for space-constrained, thermally demanding automotive and industrial rectification where reliability and surge robustness are prioritized over minimal VF.

FAQ
What is the maximum junction temperature rating for HT16G?
The HT16G has a maximum junction temperature (TJ MAX) of +150°C, verified per absolute maximum ratings table in the official TSC datasheet Version H2104. This rating enables operation in high-ambient environments such as under-hood automotive modules or enclosed industrial enclosures when paired with appropriate thermal design using its 95°C/W RθJA value. The HT16G must be operated within this limit to maintain reliability and avoid parametric shift.
Is HT16G AEC-Q101 qualified?
The base HT16G part is not automatically AEC-Q101 qualified; qualification applies only to variants marked with "H" suffix (e.g., HT16GH). Per TSC ordering information, "H" denotes AEC-Q101 qualification, and HT16G without "H" is intended for industrial/commercial use. Engineers requiring automotive qualification must specify HT16GH and verify test reports from TSC or authorized distributors.
What is the forward voltage of HT16G at 1A and 125°C?
The HT16G forward voltage is specified as 1.7V maximum at IF = 1A and TJ = 25°C. At TJ = 125°C, the typical VF decreases slightly due to semiconductor physics, but TSC does not publish a guaranteed max value at elevated temperature. Designers should use the 25°C spec with thermal derating margins or consult TSC's VF vs. TJ curve (Fig.4 in H2104) for interpolation; the HT16G remains within safe operating area up to 150°C TJ.
Which package type does HT16G use, and what are its key mechanical features?
HT16G uses the TS-1 surface-mount package: a molded epoxy case rated UL 94V-0, with pure tin-plated leads compliant with J-STD-002 solderability, polarity indicated by cathode band, and weight of approximately 0.200g. It meets JESD201 Class 2 whisker resistance and is optimized for reflow assembly in high-volume manufacturing. No through-hole variant exists for HT16G.
How does HT16G compare to HT15G in terms of electrical performance?
HT16G differs from HT15G primarily in peak reverse voltage (600V vs. 400V) and forward voltage (1.7V vs. 1.3V at 1A, 25°C). Both share identical IFSM (30A), TJ range (-55°C to +150°C), and trr (75ns for HT16G/HT17G/HT18G vs. 50ns for HT11G–HT15G). HT16G is selected when 400–600V system margin is required, accepting higher VF for enhanced voltage robustness in 400V DC bus applications.
