Product details
Overview
30CTH02S from Vishay is a dual common-cathode hyperfast recovery rectifier with 2 × 15 A average forward current per diode, 200 V peak repetitive reverse voltage, and 30 ns maximum reverse recovery time (trr) at TJ = 25 °C, 15 A, dIF/dt = 200 A/µs, VR = 160 V. It is used in high-frequency output rectification for SMPS and DC-DC converters.
For engineers reviewing the 30CTH02S datasheet, 30CTH02S pinout, 30CTH02S application, or 30CTH02S equivalent, key selection criteria include trr ≤ 35 ns, VF ≤ 1.05 V at 15 A/25 °C, RthJC ≤ 1.1 °C/W per diode, IR ≤ 10 µA at rated VR, and D2PAK package compatibility with industrial thermal management requirements.
Technical Context
The 30CTH02S integrates two independent hyperfast silicon rectifiers in a single D2PAK package with shared cathode terminals, enabling compact dual-output or interleaved converter designs. Its platinum-doped lifetime control and planar junction structure deliver tightly controlled Qrr (37 nC typ. at 25 °C) and low dI(rec)M/dt during recovery.
Designed for operation up to 175 °C junction temperature, it supports high-power density topologies where low conduction loss (VF = 0.92 V typ. at 15 A/25 °C) and minimal switching loss (trr = 26 ns typ. under full-load conditions) are critical to efficiency and thermal stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - blocks up to 200 V reverse voltage without breakdown in SMPS secondary-side applications |
| IF(AV) per diode | 15 A - supports continuous 15 A DC output current per channel at TC = 159 °C |
| trr (max) | 30 ns - enables >1 MHz switching frequencies with low recovery-related EMI and snubber losses |
| VF (typ) | 0.92 V at 15 A/25 °C - reduces conduction loss to ~13.8 W per diode at full load |
| RthJC | 1.1 °C/W per diode - allows 15 A operation with <17 °C junction-to-case rise above heatsink |
| Qrr (typ) | 37 nC at 25 °C - minimizes stored charge-induced turn-on loss in synchronous rectifier companion circuits |
| TJ max | 175 °C - qualified for industrial environments with extended thermal margin over standard 150 °C parts |
Pinout & Package
D2PAK (TO-263) surface-mount package with isolated copper tab for direct heatsink mounting. Thermal resistance optimized via low-inductance internal construction (LS = 8 nH).

Equivalent & Alternatives
The following parts are listed as comparable options for similar hyperfast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH30L06D | 600 V VRRM, 30 A IF(AV), TO-247 package, trr = 45 ns (max) | Higher voltage rating suits 400 V PFC front-end; larger TO-247 requires more PCB area and thermal mass | Select when 600 V blocking is required and D2PAK footprint is not constrained |
| IXYS MBR30200CT | Schottky construction, 200 V VRRM, 30 A IF(AV), VF = 0.95 V, no reverse recovery (trr = 0 ns) | No Qrr-related losses but limited to ≤ 150 °C TJ; unsuitable for >125 °C ambient or high-reliability industrial use | Prefer for lower-loss, lower-noise applications below 125 °C ambient where Schottky leakage is acceptable |
Compared with STTH30L06D and MBR30200CT, the 30CTH02S offers optimal balance of 200 V rating, 30 ns trr, D2PAK footprint, and 175 °C capability-making it uniquely suited for compact, thermally demanding industrial SMPS where both speed and ruggedness are mandatory.

FAQ
What is the maximum reverse recovery time (trr) specification for the 30CTH02S under full-load conditions?
The 30CTH02S has a maximum reverse recovery time of 30 ns when tested at TJ = 25 °C, IF = 15 A, dIF/dt = 200 A/µs, and VR = 160 V. At TJ = 125 °C under identical conditions, trr increases to 40 ns maximum. These values are measured per diode and reflect the device's suitability for >500 kHz switching topologies where fast recovery minimizes switching losses.
Does the 30CTH02S support surface-mount reflow assembly, and what is its lead-free status?
Yes, the 30CTH02S uses a D2PAK (TO-263) package compatible with standard lead-free reflow profiles. Per Vishay documentation, the part is Pb-free and RoHS-compliant, with marking "30CTH02S" on the case. The device meets JEDEC J-STD-020 moisture sensitivity level (MSL) 1, allowing unlimited floor life before reflow.
How is thermal management handled for the 30CTH02S given its dual-diode configuration?
The 30CTH02S features a single copper tab that serves as the thermal path for both diodes, with RthJC = 1.1 °C/W per diode. This means total thermal resistance from junction to case remains 1.1 °C/W even when both diodes conduct simultaneously at 15 A each. Effective heatsinking requires low-thermal-resistance mounting to a large-area metal plane or external heatsink.
Can the 30CTH02S be used in parallel configurations to increase current capacity?
No-parallel operation of multiple 30CTH02S devices is not recommended due to inherent forward voltage mismatch between units, which causes uneven current sharing. For higher current needs, select a single higher-rated device such as the 30CTH02-1 (TO-262 variant) or evaluate Vishay's 60 A dual hyperfast rectifiers like the 60CTH02S.
What is the reverse leakage current (IR) specification for the 30CTH02S at elevated temperature?
At TJ = 125 °C and rated VR = 200 V, the 30CTH02S exhibits a maximum reverse leakage current of 300 µA. This value is significantly higher than the 10 µA maximum at 25 °C, reflecting expected silicon behavior-but remains well within industrial design margins for most SMPS and motor drive applications.
