Product details
Overview
HT12G R0G from Taiwan Semiconductor is a 1 A, 100 V glass-passivated high-efficiency rectifier diode in TS-1 package, featuring VF = 1.0 V at IF = 1 A and TJ = 25°C, IFSM = 30 A (8.3 ms), and TJ(max) = 150°C - used in DC-DC converters and freewheeling paths in automotive-grade switching power supplies.
For engineers reviewing the HT12G R0G datasheet, HT12G R0G pinout, HT12G R0G application, or HT12G R0G equivalent, key selection criteria include repetitive peak reverse voltage (VRRM = 100 V), forward voltage drop, thermal resistance (RθJA = 95 °C/W), surge current capability, and AEC-Q101 qualification status.
Technical Context
This device is a single-die, standard recovery silicon rectifier optimized for high-efficiency switching-mode power conversion. Its glass-passivated junction ensures stable operation under thermal cycling and humidity stress, while the TS-1 package supports automated assembly and meets UL 94V-0 flammability requirements.
The HT12G R0G delivers low forward voltage (VF ≤ 1.0 V @ 1 A, 25°C) and low reverse leakage (IR ≤ 5 µA @ 25°C, rated VR), with reverse recovery time trr ≤ 50 ns under specified test conditions (IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A), enabling efficient operation in medium-frequency SMPS topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum non-repetitive reverse blocking voltage; defines safe operating range in flyback/freewheeling clamp circuits |
| IF | 1 A continuous - average forward current rating at TA = 75°C; determines steady-state conduction capability |
| IFSM | 30 A (8.3 ms half-sine) - peak surge current handling; critical for startup and fault transient resilience |
| VF | 1.0 V @ IF = 1 A, TJ = 25°C - low conduction loss directly reduces power dissipation and heatsink requirements |
| RθJA | 95 °C/W - junction-to-ambient thermal resistance; sets temperature rise per watt in PCB-mounted, still-air conditions |
| trr | ≤ 50 ns - reverse recovery time; enables use up to ~100 kHz switching frequencies without excessive switching loss |
| IR | ≤ 5 µA @ VR = 100 V, TJ = 25°C - low leakage preserves efficiency in high-impedance bias networks |
Pinout & Package
TS-1 package: surface-mount, single-anode/single-cathode configuration with cathode band marking; lead-free, pure tin-plated terminals compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential node (e.g., switch node in buck freewheel path) |
| Cathode | Forward current exit / reverse blocking terminal | Marked by band; connects to output rail or inductor return; blocks 100 V reverse polarity |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable long-term reliability under thermal cycling and humid environments per AEC-Q101 stress profiles |
| AEC-Q101 qualified option available | Validated for automotive power electronics where qualification to stress test standards is mandatory |
| UL 94V-0 molding compound | Meets flame-retardancy requirements for industrial and transportation end equipment safety certifications |
| Junction capacitance ≤ 15 pF | Minimizes capacitive coupling noise and EMI generation in high-dv/dt switching nodes |
Applications
| DC-DC Converter Output Rectification | Switching Mode Inverter Freewheeling |
|---|---|
Use Scenario: Secondary-side rectification in isolated 12 V–48 V output DC-DC converters for telecom and industrial power supplies. IC Role / Device Role / Timing Role: Power rectifier conducting during transformer secondary voltage polarity phase; handles 1 A average load current. Use Value: Low VF (1.0 V) reduces conduction loss by >15% vs. legacy 1.2 V diodes, improving full-load efficiency by ~0.8% at 1 A. | Use Scenario: Freewheeling path across inductive loads in H-bridge motor drivers and UPS inverters. IC Role / Device Role / Timing Role: Provides low-loss current recirculation path when high-side switches turn off; clamps inductive kickback. Use Value: 30 A IFSM withstands motor stall surges; 50 ns trr limits switching loss during 50–100 kHz PWM commutation. |
| Automotive Body Control Module (BCM) Power Supply | Industrial PLC Input/Output Protection |
Use Scenario: Input rectification and hold-up in 12 V automotive BCM power rails subjected to load dump transients. IC Role / Device Role / Timing Role: Primary AC/DC or DC/DC input rectifier; operates continuously at ambient up to 105°C. Use Value: AEC-Q101 qualification ensures survivability under automotive temperature cycling (-40°C to +125°C case); 100 V VRRM covers ISO 7637-2 pulse 5a (load dump). | Use Scenario: Reverse-polarity and overvoltage protection on 24 V DC sensor/actuator inputs in programmable logic controllers. IC Role / Device Role / Timing Role: Polarity guard diode placed in series with input line; blocks reverse connection and clamps transients. Use Value: 5 µA IR at 25°C prevents signal leakage in high-impedance analog sensing; TS-1 footprint enables compact board layout. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L06S | VRRM = 600 V, VF = 1.15 V @ 1 A, trr = 35 ns, SOD-123FL package | Higher voltage rating but higher VF and faster recovery; suited for higher-voltage, higher-frequency designs | Select when >100 V blocking or <50 ns trr is required; not drop-in due to different package and pinout |
| ON Semi MUR110E | VRRM = 100 V, VF = 0.95 V @ 1 A, trr = 75 ns, DO-41 package | Lower VF but slower recovery and through-hole mounting; lacks AEC-Q101 qualification | Consider for cost-sensitive, non-automotive applications where leaded assembly is acceptable |
Compared with STTH1L06S and MUR110E, the HT12G R0G offers balanced performance for 100 V automotive and industrial rectification: lower VF than MUR110E in same voltage class, better thermal resistance than STTH1L06S in surface-mount form, and AEC-Q101 readiness unmatched by either alternative.

FAQ
What is the maximum junction temperature rating for HT12G R0G?
The HT12G R0G has a maximum junction temperature (TJ(max)) of +150°C, verified per absolute maximum ratings in the official TSC datasheet (Version H2104). This rating allows reliable operation in under-hood automotive environments and enclosed industrial enclosures when derated per the forward current derating curve. Thermal design must ensure actual TJ remains below this limit under worst-case ambient and power dissipation conditions.
Does HT12G R0G meet AEC-Q101 qualification?
The base HT12G R0G part number is not AEC-Q101 qualified; however, the variant HT12GH (with "H" suffix) is explicitly listed as AEC-Q101 qualified in TSC's ordering information. HT12G R0G shares identical electrical and thermal specifications with HT12GH but lacks the formal qualification testing documentation. For automotive applications requiring certified qualification, HT12GH must be selected.
What is the reverse recovery time (trr) specification for HT12G R0G?
The HT12G R0G has a maximum reverse recovery time (trr) of 50 ns, measured under conditions IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, as specified in the Electrical Specifications table of the TSC datasheet. This value applies to the entire HT11G–HT15G group, including HT12G R0G, and supports efficient operation in switching power supplies operating up to approximately 100 kHz.
What does the "R0G" suffix indicate in HT12G R0G?
The "R0G" suffix in HT12G R0G denotes tape-and-reel packaging: "R" indicates reel packaging, "0" is a placeholder, and "G" signifies green (halogen-free) molding compound compliant with IEC 61249-2-21. This matches TSC's ordering code convention where HT1xG denotes standard TS-1 packaged devices in 5,000-unit tape-and-reel format.
Is HT12G R0G compatible with lead-free reflow soldering processes?
Yes, HT12G R0G features pure tin-plated leads and is rated for solderability per J-STD-002. Its TS-1 package is qualified for standard lead-free reflow profiles (peak temperature ≤ 260°C, per JEDEC J-STD-020), and the molding compound meets UL 94V-0 flammability requirements - making it fully compatible with RoHS-compliant, high-volume SMT assembly lines.
