Product details
Overview
HT11G R0G from Taiwan Semiconductor is a 1 A, 50 V glass-passivated high-efficiency rectifier diode in TS-1 package, featuring low forward voltage (VF ≤ 1.0 V at 1 A, 25°C), 30 A surge capability, and AEC-Q101 qualification option; used in DC-DC converters and freewheeling paths in automotive power supplies.
For engineers reviewing the HT11G R0G datasheet, HT11G R0G pinout, HT11G R0G application, or HT11G R0G equivalent, key selection criteria include repetitive peak reverse voltage (50 V), thermal resistance (95 °C/W), junction temperature range (–55 to +150 °C), and RoHS/halogen-free compliance for automotive-grade reliability validation.
Technical Context
The HT11G R0G is a single-die, planar passivated silicon rectifier optimized for high-efficiency switching-mode power conversion. Its 50 V VRRM rating and 1.0 V typical VF at 1 A enable low conduction loss in low-voltage DC-DC stages, while the 30 A IFSM supports transient surge handling in inductive load circuits.
Thermally, the TS-1 package delivers 95 °C/W junction-to-ambient resistance, and the device operates across –55 to +150 °C junction temperature with <5 µA reverse leakage at 25°C - critical for stable freewheeling performance in automotive ambient conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - maximum repetitive reverse blocking voltage; defines safe operating limit in DC-DC flyback or buck freewheeling nodes |
| IF | 1 A continuous - average forward current rating; sets steady-state power dissipation boundary (P ≈ 1.0 W at VF = 1.0 V) |
| IFSM | 30 A (8.3 ms half-sine) - surge withstand capability; protects against inrush and inductive kickback in motor or solenoid drivers |
| VF | ≤ 1.0 V @ 1 A, 25°C - low conduction loss enabling >92% efficiency in 5–12 V output converters |
| RθJA | 95 °C/W - thermal resistance defining junction temperature rise under natural convection; requires minimal heatsinking at ≤0.5 W dissipation |
| IR | ≤ 5 µA @ 50 V, 25°C - low leakage preserves efficiency in high-impedance bias networks and standby modes |
| TJ Range | –55 to +150 °C - extended automotive-grade operating envelope supporting under-hood and engine-control module deployment |
Pinout & Package
TS-1 package: molded epoxy case with pure tin-plated leads, polarity indicated by cathode band, UL 94V-0 rated, JESD 201 Class 2 whisker compliant, weight ≈ 0.200 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry node | Connected to switch node or inductor output in buck/flyback freewheeling path; must handle full IF and IFSM |
| Cathode | Current exit node | Connected to ground or output rail; marked by visible band; carries return current and defines reverse-blocking orientation |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enhances moisture resistance and long-term reliability in humid or thermally cycled automotive environments |
| AEC-Q101 qualified option | Validated for automotive electronics per stress test requirements (HTOL, TC, UHAST); HT11G R0G denotes standard grade, not AEC version |
| RoHS & halogen-free | Complies with IEC 61249-2-21; enables use in EU/China automotive supply chains without material declaration exceptions |
| Low VF and high IFSM | Enables compact, high-efficiency 1 A rectification without forced air cooling in space-constrained modules |
Applications
| Automotive DC-DC Converters | Industrial SMPS Freewheeling |
|---|---|
Use Scenario: Step-down conversion from 12 V battery to 5 V/3.3 V for infotainment and ADAS ECUs. IC Role / Device Role / Timing Role: Freewheeling diode in synchronous or non-synchronous buck converter output stage. Use Value: 1.0 V VF minimizes conduction loss at 1 A load, improving system efficiency by ~0.8% vs. higher-VF alternatives; 50 V VRRM safely covers battery transients up to 16 V. | Use Scenario: Output rectification in 24 V input industrial switch-mode power supplies. IC Role / Device Role / Timing Role: Unidirectional current path during off-cycle of main switch; handles reverse recovery in high-frequency operation. Use Value: 50 ns trr and <5 µA IR ensure low switching loss and stable regulation at 100–500 kHz; TS-1 footprint allows direct replacement of legacy DO-41 devices. |
| LED Driver Flyback Snubber | Power Tool Battery Protection |
Use Scenario: Clamp diode in flyback snubber network for constant-current LED drivers. IC Role / Device Role / Timing Role: Transient energy diversion path during MOSFET turn-off; absorbs leakage inductance spikes. Use Value: 30 A IFSM withstands repeated 20–50 A spike events; glass passivation prevents degradation under high dv/dt stress in LED driver EMI filters. | Use Scenario: Reverse-polarity protection and charge-path isolation in cordless power tool battery packs. IC Role / Device Role / Timing Role: Series blocking diode between battery cell stack and motor controller; prevents backfeed during fault or disconnect. Use Value: –55 to +150 °C TJ range ensures operation during rapid discharge heating; 0.200 g mass supports lightweight pack design without compromising surge robustness. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R06U | 1 A, 600 V, TO-220AC package, VF = 1.15 V @ 1 A; higher VRRM but larger footprint and higher VF | Suitable for higher-voltage industrial SMPS where 50 V rating is insufficient | Select when >100 V reverse blocking is required; avoid for 12 V systems due to unnecessary overdesign and cost |
| SB150-E3/54 | 1 A, 50 V, DO-41 package, VF = 0.95 V @ 1 A, RθJA = 120 °C/W; lower VF but worse thermal performance | Better for low-power consumer adapters where board space is less constrained than thermal margin | Prefer only if PCB layout allows larger DO-41 pad area and ambient temperature stays below 60°C |
Compared with STTH1R06U and SB150-E3/54, the HT11G R0G offers optimal balance of low VF (≤1.0 V), industry-standard TS-1 footprint, and 95 °C/W thermal resistance - making it ideal for space- and efficiency-critical 12 V automotive DC-DC modules where 50 V blocking suffices.

FAQ
What is the maximum junction temperature rating for HT11G R0G?
The HT11G R0G has a maximum junction temperature (TJ MAX) of +150 °C and a minimum of –55 °C, enabling operation in under-hood automotive environments and industrial enclosures with elevated ambient temperatures. This rating is validated per JEDEC standards and aligns with TSC's AEC-Q101-qualified variants. The HT11G R0G maintains stable electrical parameters across this full range when derated per the forward current derating curve in the datasheet.
Is HT11G R0G pin-compatible with other HTxG series devices like HT12G or HT13G?
Yes - all HTxG devices including HT11G R0G share identical TS-1 package dimensions, pinout (anode/cathode), and mechanical mounting. Only VRRM, VF, and trr differ across the series. Engineers may substitute HT11G R0G for HT12G in 50 V designs without layout change, but must verify that 100 V VRRM of HT12G is not required for transient margin in their specific application.
Does HT11G R0G meet automotive qualification standards?
The HT11G R0G itself is the standard-grade version; however, the HT11G-H variant is AEC-Q101 qualified. HT11G R0G shares the same die, passivation, and TS-1 construction as the AEC-Q101 version, differing only in test screening. For non-safety-critical automotive subsystems (e.g., body control modules), HT11G R0G is widely deployed - but safety-critical applications require explicit HT11G-H ordering and certification documentation.
What is the reverse recovery time (trr) specification for HT11G R0G?
The HT11G R0G has a typical reverse recovery time (trr) of 50 ns under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A test conditions. This fast recovery minimizes switching losses in high-frequency DC-DC converters operating above 100 kHz. The value is confirmed in the "ELECTRICAL SPECIFICATIONS" table on page 2 of the H2104 datasheet and applies identically to all HT11G–HT15G variants.
Can HT11G R0G be used in surface-mount assembly processes?
Yes - the HT11G R0G uses TS-1 package with pure tin-plated leads compliant with J-STD-002 solderability requirements. It supports both wave and reflow soldering profiles, including lead-free (SnAgCu) processes. The 0.200 g weight and UL 94V-0 molding compound ensure mechanical stability during thermal cycling. Reflow peak temperature must not exceed 260 °C for ≤10 seconds to maintain junction integrity.
