Product details
Overview
SF65GH from Taiwan Semiconductor is a 300V, 6A AEC-Q101 qualified super fast rectifier diode in DO-201AD package, featuring 35ns reverse recovery time, 1.300V forward voltage at 6A/25°C, and 150A surge capability - used in automotive-grade DC-DC converters and freewheeling paths.
For engineers reviewing the SF65GH datasheet, SF65GH pinout, SF65GH application, or SF65GH equivalent, key selection criteria include VRRM=300V, IF=6A, trr=35ns, AEC-Q101 qualification, and DO-201AD thermal performance (RθJL=5°C/W).
Technical Context
This super fast rectifier uses a single-die silicon PN junction optimized for high-frequency switching. Its 35ns reverse recovery time enables efficient operation in 100–500kHz SMPS topologies, while the 300V VRRM rating supports 24V–48V input bus systems with margin.
The device operates across –55°C to +150°C junction temperature range and delivers low conduction loss (VF ≤ 1.300V @ 6A) combined with robust surge handling (IFSM = 150A, 8.3ms half-sine), meeting automotive reliability requirements per AEC-Q101.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 300 V - Maximum repetitive reverse voltage; sets safe operating limit for 24V/48V DC-DC primary-side clamping |
| IF | 6 A - Continuous forward current; defines steady-state power dissipation (Pcond ≈ 7.8W @ VF=1.3V) |
| trr | 35 ns - Reverse recovery time; enables high-frequency switching with minimal turn-off loss in buck/flyback converters |
| IFSM | 150 A - Non-repetitive surge current (8.3ms); withstands inrush and fault transients without failure |
| RθJL | 5 °C/W - Junction-to-lead thermal resistance; allows direct heatsinking via PCB copper pour or lead frame |
| Junction Cap. (CJ) | 50 pF @ 1MHz, 4V - Low capacitance minimizes switching noise and EMI in high-dv/dt applications |
Pinout & Package
DO-201AD axial-leaded package with cathode band marking; leads are pure tin-plated, J-STD-002 solderable, and meet JESD201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Forward current entry | Connected to source/switch node in freewheeling path; requires low-inductance layout |
| Cathode (Lead 2, banded end) | Forward current exit / reverse blocking terminal | Connected to output rail or ground return; polarity must be observed to prevent breakdown |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive under-hood use including temperature cycling, HTRB, and UHAST |
| Super fast recovery (35ns) | Reduces switching losses vs. standard rectifiers in >100kHz converters |
| Low VF (1.300V @ 6A) | Minimizes conduction loss and thermal stress in space-constrained power stages |
| DO-201AD with RθJL = 5°C/W | Enables >3W continuous dissipation on 1-in² 2oz Cu without external heatsink |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH6L06S | VRRM=600V, trr=30ns, VF=1.25V @ 6A - higher voltage rating, slightly faster recovery | Preferred in 400V+ PFC boost outputs; less optimal for 300V-class designs due to over-spec'd voltage | Select when system requires >400V reverse margin or sub-30ns trr; verify layout compatibility with TO-220AC footprint |
| ON Semi MUR620 | VRRM=200V, trr=35ns, VF=1.15V @ 6A - lower voltage, lower VF, same trr | Suitable for 24V/48V secondary-side rectification but unsafe at 300V reverse bias | Choose only for ≤200V applications; not a drop-in replacement for SF65GH's 300V requirement |
Compared with STTH6L06S and MUR620, SF65GH uniquely balances 300V rating, 35ns recovery, AEC-Q101 compliance, and DO-201AD thermal performance - making it optimal for automotive and industrial 24–48V systems requiring validated reliability and precise voltage margin.

FAQ
What is the peak repetitive reverse voltage rating of SF65GH?
The SF65GH has a peak repetitive reverse voltage (VRRM) rating of 300 V. This value is confirmed in the Absolute Maximum Ratings table of the official TSC datasheet (Version G2105), where SF65G is explicitly listed under the 300V column. It defines the maximum allowable reverse-biased voltage before breakdown occurs under normal operating conditions.
Is SF65GH qualified to AEC-Q101 standards?
Yes, SF65GH is AEC-Q101 qualified. The "H" suffix in the ordering code explicitly denotes AEC-Q101 qualification per the Ordering Information section of the TSC datasheet. This includes stress testing for temperature cycling, high-temperature reverse bias (HTRB), and unbiased highly accelerated stress test (UHAST) - confirming suitability for automotive under-hood applications.
What is the forward voltage of SF65GH at 6A and 25°C?
The forward voltage (VF) of SF65GH is 1.300 V maximum at IF = 6 A and TJ = 25°C, as specified in the Electrical Specifications table under the SF65G/SF66G row. This value reflects worst-case conduction loss under nominal conditions and is critical for thermal design and efficiency calculations in power stages.
Does SF65GH have a specified reverse recovery time?
Yes, SF65GH has a reverse recovery time (trr) of 35 ns maximum, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This parameter is listed in the Electrical Specifications table and applies to SF65G–SF68G variants. It directly impacts switching loss and EMI in high-frequency converters.
What package type does SF65GH use, and what are its thermal characteristics?
SF65GH uses the DO-201AD axial-leaded package. Its thermal performance includes a junction-to-lead thermal resistance (RθJL) of 5°C/W and junction-to-ambient (RθJA) of 40°C/W, per the Thermal Performance table. These values enable effective heat transfer through the leads to PCB copper or chassis, supporting >3W continuous dissipation in typical layouts.
