Product details
Overview
STTH2L06A from STMicroelectronics is a 600 V, 2 A ultrafast recovery rectifier diode using Turbo 2 planar platinum-doped technology, optimized for high-frequency SMPS and transistor base-drive circuits in axial-SMA package. It delivers low conduction loss (VF(typ) = 0.85 V at 150 °C), negligible switching loss, and fast reverse recovery (trr(max) = 60 ns), enabling efficient free-wheeling and polarity protection in compact power converters.
For engineers reviewing the STTH2L06A datasheet, STTH2L06A pinout, STTH2L06A application, or STTH2L06A equivalent, key selection criteria include junction temperature rating (Tj = 175 °C), thermal resistance (Rth(j-l) = 30 °C/W), surge current capability (IFSM = 35 A), and DO-41/SMA/SMB package compatibility for layout-constrained designs.
Technical Context
The STTH2L06A employs ST's Turbo 2 Pt-doping process to achieve low VF and ultrafast trr without soft-recovery trade-offs. Its dynamic performance is characterized under standardized conditions: IF = 1 A, dIF/dt = 50 A/µs, VR = 30 V for trr measurement, and Tj = 25 °C/150 °C for static parameter validation.
Thermal design relies on validated junction-to-lead resistance (30 °C/W for SMA), with derating curves confirming stable operation up to 175 °C junction temperature. The device exhibits minimal forward recovery voltage (VFP = 9 V) and time (tfr = 100 ns), supporting high dIF/dt switching in resonant and synchronous rectifier topologies.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR260 | 600 V, 2 A, trr = 65 ns (max), VF = 1.25 V (typ at 25 °C), Rth(j-l) = 35 °C/W | Higher VF increases conduction loss by ~0.4 W at 2 A; slightly slower trr affects EMI filtering in >200 kHz designs | Preferred where cost sensitivity outweighs thermal or high-frequency performance needs |
| Vishay VS-2EY60 | 600 V, 2 A, trr = 50 ns (max), VF = 0.95 V (typ at 150 °C), Rth(j-l) = 28 °C/W, SMB package | Faster trr and lower thermal resistance enable tighter layout and higher ambient operation, but SMB footprint differs from SMA | Selected when board space allows SMB and sub-50 ns trr is required for EMI-critical applications |
Compared with MUR260 and VS-2EY60, STTH2L06A offers the best balance of low VF at high temperature, proven 60 ns trr consistency, and SMA package compatibility-making it optimal for thermally dense, mid-frequency SMPS where reliability and manufacturability are prioritized.

FAQ
What is the maximum allowable lead temperature during soldering for STTH2L06A?
The STTH2L06A SMA package is rated for lead-free reflow per JEDEC J-STD-020. Peak solder temperature must not exceed 260 °C for ≤30 seconds, with ramp rates limited to ≤3 °C/s. Hand-soldering requires iron tip temperature ≤350 °C and contact time <3 seconds per lead to avoid internal delamination or bond wire damage.
Does STTH2L06A support bidirectional current flow in synchronous rectification?
No-STTH2L06A is a unidirectional ultrafast rectifier diode. It conducts only from anode to cathode and blocks reverse voltage up to 600 V. For synchronous rectification, an actively controlled MOSFET (e.g., STripFET™ H6) must be used in place of this diode; STTH2L06A serves only as a passive, asymmetric switching element.
How does the 0.85 V VF(typ) at 150 °C compare to room-temperature VF?
At Tj = 25 °C and IF = 2 A, VF is 1.3 V (max); at Tj = 150 °C, VF drops to 0.85 V (typ). This negative temperature coefficient improves thermal stability in parallel configurations and reduces conduction loss under high-ambient conditions typical in enclosed power supplies.
Can STTH2L06A replace STTH2R06 in an existing design?
STTH2R06 is a 600 V, 2 A fast recovery diode with trr(max) = 150 ns and VF = 1.15 V (typ at 25 °C). STTH2L06A offers superior performance: 60 ns trr cuts switching loss by ~60%, and 0.85 V VF at 150 °C lowers conduction loss. Layout and footprint are identical (SMA), enabling drop-in replacement with measurable efficiency gain.
