Product details
Overview
STTH2L06 from STMicroelectronics is a 600 V, 2 A ultrafast recovery rectifier diode using Turbo 2 planar Pt-doping technology, optimized for high-frequency SMPS and transistor base-drive circuits with low conduction and switching losses. It delivers typ. VF = 0.85 V at 150 °C and max. trr = 60 ns under IF = 1 A, dIF/dt = 50 A/µs, VR = 30 V, enabling efficient free-wheeling and polarity protection in inverters.
For engineers reviewing the STTH2L06 datasheet, STTH2L06 pinout, STTH2L06 application, or STTH2L06 equivalent, key selection criteria include reverse recovery time (trr ≤ 60 ns), junction temperature rating (Tj = 175 °C), thermal resistance (Rth(j-l) = 30 °C/W for SMA), and package-specific current derating (IF(AV) = 2 A at Tl = 100 °C for SMA).
Technical Context
This diode employs platinum-doped silicon to achieve ultrafast carrier lifetime control, minimizing minority-carrier storage and enabling sub-100 ns reverse recovery. Its planar structure ensures stable trr across temperature and dIF/dt variation, with typical trr = 60 ns at 25 °C and < 85 ns at 150 °C.
The device supports three standard packages-DO-41, SMA, and SMB-with distinct thermal resistances (Rth(j-l): 35 / 30 / 25 °C/W) and mounting constraints. Each variant shares identical electrical specs but differs in RMS current rating (IF(RMS) = 7 A) and surge capability (IFSM = 35–45 A depending on package and pulse duration).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - blocks up to 600 V repetitive reverse voltage without breakdown, suitable for 400 V DC bus applications with safety margin. |
| IF(AV) | 2 A - average forward current rating at specified lead temperature (100 °C for SMA), defining continuous conduction capability. |
| VF (typ) | 0.85 V at Tj = 150 °C - low forward drop reduces conduction loss in high-duty-cycle operation. |
| trr (max) | 60 ns - ultrafast recovery minimizes switching loss and EMI in >100 kHz SMPS topologies. |
| Tj (max) | 175 °C - enables operation in thermally constrained environments without derating below ambient + 125 °C. |
| Rth(j-l) | 30 °C/W (SMA) - thermal resistance from junction to lead determines heatsinking requirements for 2 A continuous load. |
| IR (max) | 85 µA at Tj = 150 °C - low leakage preserves efficiency in high-impedance bias networks and standby modes. |
Pinout & Package
STTH2L06 is a two-terminal axial or surface-mount diode: anode and cathode only. Cathode identified by band marking. Available in DO-41 (axial), SMA (DO-214AC), and SMB (DO-214AA) packages. No internal circuitry or control pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of circuit; must withstand peak forward surge (IFSM = 35–45 A). |
| Cathode | Forward current exit / reverse blocking terminal | Marked with band; connected to higher-potential node; sustains full VRRM during off-state. |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast recovery | trr ≤ 60 ns ensures minimal switching loss and reduced snubber requirements in hard-switched converters. |
| High Tj rating | 175 °C maximum junction temperature allows reliable operation in sealed enclosures or near heat sources. |
| Low VF at high Tj | 0.85 V typ. at 150 °C maintains efficiency in thermally stressed conditions where conventional diodes degrade. |
| Pt-doped silicon | Turbo 2 process provides consistent trr vs. temperature and dIF/dt, improving design predictability. |
Applications
| Switch-Mode Power Supplies | Motor Drive Free-Wheeling |
|---|---|
Use Scenario: Output rectification in 100–500 kHz AC/DC adapters and server PSUs with 380–400 V DC input. IC Role / Device Role / Timing Role: Ultrafast power rectifier handling continuous 2 A output current with minimal voltage overshoot during turn-off. Use Value: 60 ns trr limits reverse recovery charge (Qrr) to < 20 nC, reducing MOSFET turn-on loss and EMI generation. | Use Scenario: Inductive load flyback path in 3-phase BLDC motor gate driver stages operating at 20–100 kHz PWM. IC Role / Device Role / Timing Role: Freewheeling diode clamping back-EMF spikes across low-side IGBTs or MOSFETs. Use Value: 175 °C Tj rating permits placement adjacent to power switches without thermal derating. |
| Base Drive Protection | Polarity Reversal Protection |
Use Scenario: Clamping diode in bipolar transistor base drive circuits for industrial PLC output modules. IC Role / Device Role / Timing Role: Fast-turn-off clamp limiting base-emitter reverse voltage during transistor saturation switching. Use Value: Low trr prevents latch-up in high-gain Darlington configurations by avoiding minority-carrier injection delay. | Use Scenario: Input protection in 12–48 V DC power inputs for telecom line cards and IoT edge controllers. IC Role / Device Role / Timing Role: Series polarity guard diode preventing damage from accidental reverse battery connection. Use Value: 0.85 V VF at 150 °C keeps insertion loss below 1.7% at 2 A, preserving system efficiency over temperature. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R06 | Same die, DO-41 only; IF(AV) rated at Tl = 90 °C (vs. 100 °C for SMA variant); Rth(j-l) = 35 °C/W. | Limited to lower-power, through-hole designs; not suitable for SMT volume production or high-density layouts. | Select when axial mounting and legacy PCB compatibility are required; avoid in thermally dense SMT assemblies. |
| ES1J (Vishay) | 600 V, 1 A, trr = 35 ns (faster), VF = 0.95 V (higher), Tj = 150 °C (lower), SMB package only. | Better trr for >500 kHz operation but lower current rating and thermal limit restrict use to sub-1 A outputs. | Prefer for ultra-high-frequency auxiliary rails where speed outweighs current capacity; not drop-in for 2 A main outputs. |
Compared with STTH2R06 and ES1J, STTH2L06 uniquely balances 2 A average current, 60 ns trr, 175 °C Tj, and multi-package flexibility-making it optimal for mainstream high-efficiency SMPS and motor drive freewheeling where thermal headroom and reliability are critical.

FAQ
What is the maximum allowable junction temperature for STTH2L06?
The absolute maximum junction temperature (Tj) is 175 °C, verified per Table 2 in the official datasheet (Doc ID10758 Rev 2). This rating applies across all packages and defines the upper thermal limit for safe continuous operation; exceeding it risks irreversible degradation of the Pt-doped junction.
Does STTH2L06 have a built-in thermal shutdown feature?
No, STTH2L06 is a passive rectifier diode with no integrated thermal sensing or shutdown circuitry. Thermal management relies entirely on external design-PCB copper area, heatsinking, and airflow-as specified in thermal resistance tables (Rth(j-l) = 30 °C/W for SMA).
Can STTH2L06 be used in place of a Schottky diode?
No-it is a PN junction ultrafast diode, not a Schottky. While both offer fast switching, STTH2L06 has higher VF (0.85 V vs. ~0.4–0.6 V for Schottky) but superior VRRM (600 V vs. typically ≤ 200 V for Schottky), making it unsuitable for low-voltage, high-efficiency apps where Schottky excels.
What is the cathode marking method for STTH2L06 in SMA package?
The cathode is marked by a visible band on the body end of the SMA package, consistent with JEDEC DO-214AC standards. This band aligns with the cathode terminal (pin 2) in the standard SMA footprint, as shown in Figure 15 of the datasheet.
