Product details
Overview
STTH3002PI from STMicroelectronics is an ultrafast recovery silicon diode using platinum-doped planar technology, rated for 200 V repetitive peak reverse voltage and 30 A average forward current at Tc = 115 °C in DOP3I package. It delivers 22 ns typical reverse recovery time, 0.77 V typical forward voltage at 25 A/125 °C, and operates up to 175 °C junction temperature-optimized for high-frequency inverters and transistor base-drive circuits.
For engineers reviewing the STTH3002PI datasheet, STTH3002PI pinout, STTH3002PI application, or STTH3002PI equivalent, key selection criteria include low conduction loss (P = 0.67×IF(AV) + 0.007×IF²(RMS)), negligible switching losses, thermal resistance of 1.8 °C/W (junction-to-case), and compatibility with polarity protection and freewheeling topologies requiring fast soft recovery.
Technical Context
The STTH3002PI employs Pt-doping to achieve controlled carrier lifetime, enabling ultrafast trr (22 ns typ.) with soft recovery characteristics critical for minimizing EMI in SMPS and motor drive snubbers. Its low VF (0.77 V @ 25 A/125 °C) and low IR (20 µA @ 25 °C) reduce both conduction and leakage losses across wide temperature ranges.
Designed for hard-switched topologies, it supports surge currents up to 300 A (10 ms, sinusoidal) and maintains stable dynamic parameters-including QRR and IRM-across dIF/dt from 50 to 200 A/µs and junction temperatures from 25 °C to 125 °C, as verified in Figures 6–8 of the official datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Withstands repetitive reverse voltage up to 200 V without breakdown, suitable for 100–120 VAC input rectification and 200 V bus clamping. |
| IF(AV) | 30 A at Tc = 115 °C - Sustains continuous forward current of 30 A when case temperature is held at 115 °C in DOP3I package. |
| trr (typ) | 22 ns - Enables operation above 100 kHz switching frequencies with minimal turn-off loss and reduced RFI generation. |
| VF (typ) | 0.77 V @ 25 A, 125 °C - Low forward drop reduces conduction loss by ~15% vs. standard fast diodes, improving efficiency in high-current DC links. |
| Rth(j-c) | 1.8 °C/W - Junction-to-case thermal resistance allows direct heatsink mounting in DOP3I package for reliable 30 A operation without forced air. |
| Tj (max) | 175 °C - High maximum junction temperature supports operation in compact, thermally constrained industrial enclosures. |
| QRR (typ) | 35 nC @ IF = 30 A, VR = 160 V, Tj = 125 °C - Low recovered charge minimizes voltage overshoot during commutation in IGBT-based inverters. |
Pinout & Package
STTH3002PI is housed in the DOP3I package-a surface-mount variant of DO-247 with enhanced thermal pad and optimized footprint for high-power PCB mounting. The device has two terminals: anode and cathode, with the cathode marked by a band on the molded body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., switch node or ground return) in freewheeling paths; must handle full load current and surge peaks. |
| Cathode | Forward current exit / reverse blocking terminal | Marked with band; connects to higher-potential rail (e.g., DC bus); withstands 200 V reverse bias and absorbs reverse recovery energy. |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast soft recovery | trr = 22 ns (typ.) with low IRM (7.6 A) ensures minimal voltage ringing and EMI in hard-switched converters. |
| Low conduction loss | VF = 0.77 V @ 25 A/125 °C enables >95% efficiency in 30 A output stages without active cooling. |
| High surge capability | IFS M = 300 A (10 ms, sinusoidal) supports robust start-up and fault conditions in motor drives and UPS systems. |
| High-temperature operation | Tj(max) = 175 °C and stable IR < 200 µA @ 150 °C allow use in sealed industrial environments without derating. |
| ECOPACK® compliance | Lead-free second-level interconnect meets JEDEC JESD97; RoHS-compliant packaging for global manufacturing. |
Applications
| Motor Drive Freewheeling | Solar Inverter DC Link |
|---|---|
|
Use Scenario: Used as a freewheeling diode across IGBTs in three-phase inverter legs of 3–5 kW brushless DC motor drives. IC Role / Device Role / Timing Role: Provides low-loss current recirculation path during IGBT turn-off; soft recovery suppresses voltage spikes that could trigger false triggering. Use Value: 22 ns trr and 35 nC QRR reduce switching loss by ~20% vs. standard fast diodes, lowering heatsink requirements by one size tier. |
Use Scenario: Positioned in the DC link stage of string inverters to clamp transient overvoltage and absorb reactive energy from PV array capacitance. IC Role / Device Role / Timing Role: Acts as a bidirectional clamping diode during grid synchronization transients; high VRRM prevents breakdown under 200 V DC bus surges. Use Value: 200 V VRRM rating and 175 °C Tj(max) ensure reliability in outdoor-rated inverters exposed to ambient temperatures up to 85 °C. |
| SMPS Secondary Rectification | Polarity Protection Circuit |
|
Use Scenario: Rectifies 100–200 kHz transformer secondary output in telecom and server PSUs delivering 30–50 A at 12 V or 48 V. IC Role / Device Role / Timing Role: Conducts forward current during positive half-cycle; ultrafast recovery eliminates tail current that would otherwise increase MOSFET turn-on loss. Use Value: 0.77 V VF at 125 °C reduces conduction loss by 0.4 W per diode vs. 0.95 V alternatives, directly improving full-load efficiency. |
Use Scenario: Placed in series with power input to protect downstream circuitry from reverse battery connection in industrial controllers and battery-powered gateways. IC Role / Device Role / Timing Role: Blocks reverse current flow while conducting forward current with minimal voltage drop during normal operation. Use Value: 20 µA IR at 25 °C and <200 µA at 150 °C prevent standby power drain; 30 A IF(AV) supports hot-swap capable 24 V/30 A inputs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH30L06D | 600 V VRRM, 30 A IF(AV), trr = 35 ns (typ.), VF = 1.45 V @ 30 A/125 °C | Higher voltage rating but higher VF and slower recovery; suited for 400 V DC bus systems, not 200 V designs. | Select only if system requires >200 V reverse blocking; avoid for 200 V applications due to unnecessary VF penalty. |
| IXYS MUR3020CT | 200 V VRRM, 30 A IF(AV), trr = 30 ns (typ.), VF = 0.92 V @ 30 A/125 °C, TO-220AB package | Slower recovery and higher VF; through-hole mounting limits high-frequency layout density. | Acceptable for cost-sensitive, lower-frequency (<50 kHz) designs where DOP3I surface-mount is not required. |
Compared with STTH30L06D and MUR3020CT, STTH3002PI offers the lowest trr and VF in the 200 V/30 A class with surface-mount DOP3I thermal performance-making it optimal for space-constrained, high-efficiency 100+ kHz inverters where soft recovery and thermal management are critical.

FAQ
What is the maximum allowable case temperature for continuous 30 A operation?
The STTH3002PI is rated for 30 A average forward current at Tc = 115 °C in the DOP3I package, as specified in Table 1 of the datasheet. Exceeding this case temperature requires derating per the IF(AV) vs. Tc curve in Figure 1; at Tc = 135 °C, IF(AV) drops to approximately 22 A.
Does STTH3002PI have a built-in thermal protection mechanism?
No, STTH3002PI is a passive discrete diode without integrated thermal shutdown or sensing. Safe operation depends on external thermal design-such as heatsink sizing, copper area, and airflow-to maintain Tj ≤ 175 °C under worst-case load and ambient conditions.
Can STTH3002PI be used in parallel configurations for higher current handling?
Yes, but only with careful layout: matched trace lengths, symmetrical thermal coupling, and individual current-sharing resistors (0.01–0.02 Ω) are required. The device's positive VF temperature coefficient aids natural current sharing, but mismatched thermal paths can cause imbalance exceeding 20% at full load.
Is the DOP3I package lead-free and RoHS compliant?
Yes, STTH3002PI is supplied in ECOPACK®-compliant DOP3I packaging with lead-free second-level interconnect, certified per JEDEC JESD97 and fully RoHS compliant. The "ECOPACK" marking appears on both the device body and inner box label.
