Product details
Overview
STTH30ST06WY from STMicroelectronics is an ultrafast high-voltage silicon rectifier diode in DO-247 package, rated for 600 V repetitive peak reverse voltage, 30 A average forward current, and 39 ns typical reverse recovery time. It uses Turbo 2 technology with aluminum ribbon bonding, delivers low thermal resistance (1.25 °C/W), and is AEC-Q101 qualified for automotive power conversion.
For engineers reviewing the STTH30ST06WY datasheet, STTH30ST06WY pinout, STTH30ST06WY application, or STTH30ST06WY equivalent, key selection criteria include conduction loss modeling (P = 1.45×IF(AV) + 0.025×IF²(RMS)), soft recovery behavior (S-factor = 0.3), junction temperature range (–40 to +175 °C), and DO-247 mechanical footprint compliance.
Technical Context
This device implements a planar epitaxial ultrafast recovery structure optimized for continuous conduction mode (CCM) operation in boost and output rectification stages. Its low reverse recovery charge (QRR) and controlled softness factor minimize switching losses and EMI in high-frequency SMPS topologies.
The aluminum ribbon bonding and DO-247 package provide robust thermal performance (Rth(j-c) = 1.25 °C/W) and mechanical reliability under thermal cycling, supporting automotive-grade transient stress requirements per AEC-Q101.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum repetitive reverse blocking capability for 600 V bus applications |
| IF(AV) | 30 A - Average forward current at Tc = 65 °C, defining continuous power handling in heatsink-mounted designs |
| trr (typ) | 39 ns - Ultrafast reverse recovery time enabling >100 kHz switching without excessive loss or ringing |
| VF (typ) | 1.75 V @ 30 A, 125 °C - Forward voltage drop used directly in conduction loss calculation |
| Rth(j-c) | 1.25 °C/W - Junction-to-case thermal resistance, critical for heatsink sizing in automotive under-hood environments |
| S-factor | 0.3 - Soft recovery characteristic reducing voltage overshoot and EMI during turn-off |
| Tj range | –40 to +175 °C - Extended junction temperature rating enabling operation in engine bay and industrial enclosures |
Pinout & Package
STTH30ST06WY is housed in a DO-247 through-hole package with two terminals: anode and cathode. The case serves as the cathode connection, and the leaded terminal is the anode. Mounting requires 0.55 N·m torque (max 1.0 N·m) on the mounting screw.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (lead) | Forward current entry point | Connected to input/switching node in boost or flyback rectifier stage |
| Cathode (case) | Forward current exit / heat path | Electrically and thermally connected to heatsink; must be isolated from other potentials |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXYS MUR3060CT | TO-247 package, dual-diode configuration, 600 V, 30 A, trr = 50 ns (typ) | Requires dual-diode layout; higher trr increases switching loss in >80 kHz designs | Preferred where dual-diode symmetry or legacy TO-247 footprint is required |
| Vishay VS-30CPH06-M3 | TO-247AC package, single-diode, 600 V, 30 A, trr = 45 ns (typ), VF = 1.85 V @ 30 A | Higher VF increases conduction loss; no AEC-Q101 qualification | Acceptable for industrial non-automotive use where cost sensitivity outweighs qualification needs |
Compared with MUR3060CT and VS-30CPH06-M3, STTH30ST06WY offers superior softness (S-factor = 0.3 vs. ≥0.45), lower thermal resistance (1.25 vs. ≥1.5 °C/W), and AEC-Q101 validation-making it optimal for automotive CCM boost and high-reliability industrial rectification where EMI control and thermal margin are critical.

FAQ
What is the maximum recommended mounting torque for STTH30ST06WY?
The DO-247 package specifies a recommended torque value of 0.55 N·m, with an absolute maximum of 1.0 N·m. Exceeding this risks cracking the epoxy body or damaging internal ribbon bonds, compromising thermal performance and long-term reliability under thermal cycling.
Does STTH30ST06WY require a heatsink in all applications?
Yes-due to its 30 A IF(AV) rating and 1.75 V VF, power dissipation exceeds 50 W at full load. The 1.25 °C/W Rth(j-c) requires a heatsink to maintain Tj ≤ 175 °C; derating is mandatory above 65 °C case temperature per the datasheet's IF(AV) vs. Tc curve.
How does the aluminum ribbon bonding improve reliability over wire bonding?
Aluminum ribbon bonding provides larger cross-sectional area and lower interfacial stress versus gold wire, resulting in 3× higher IFSM (160 A), improved thermal cycling endurance (>10⁵ cycles), and reduced bond fatigue failure risk in automotive under-hood environments with wide ΔT swings.
Can STTH30ST06WY replace standard FRD diodes in existing 600 V designs?
Yes-its pin-compatible DO-247 footprint and identical VRRM/IF(AV) ratings allow drop-in replacement, but designers must verify reduced trr (39 ns vs. 60–100 ns) does not induce unintended ringing due to faster dV/dt; minor snubber adjustment may be needed in high-Lσ layouts.
