Product details
Overview
SURA8215T3G-VF01 from onsemi is an ultra-fast recovery power rectifier diode rated for 150 V peak repetitive reverse voltage and 2 A average forward current at TL = 135 °C, with low forward voltage drop (0.77 V max at 2.0 A, TJ = 150 °C) and 35 ns reverse recovery time - ideal for high-frequency switching power supplies and flyback converter freewheeling paths in compact surface-mount designs.
For engineers reviewing the SURA8215T3G-VF01 datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q101 qualification, SMA package thermal resistance (24 °C/W junction-to-lead), 175 °C maximum junction temperature, and Pb-free, RoHS-compliant construction suitable for automotive and industrial surface-mount rectification.
Technical Context
This device implements a glass-passivated PN junction optimized for fast switching with minimal stored charge, enabling efficient high-frequency rectification up to several hundred kHz. Its 35 ns trr and low Qrr support reduced switching losses in SMPS output stages and snubberless flyback topologies.
The SMA package (Case 403D) provides mechanical robustness and thermal performance validated under JEDEC standards, with 260 °C/10 s solderability and polarity band marking for cathode identification - critical for automated assembly and reliability in thermally stressed environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NRVUA220VT3G | 200 V VRRM, same SMA package, identical trr (35 ns), higher VF (0.82 V @ 2 A, 150 °C) | Supports higher input voltage ranges (e.g., 230 VAC systems); slightly higher conduction loss | Select when system requires ≥200 V blocking with no layout change |
| MURA220T3G | 200 V VRRM, same thermal specs, non-automotive grade (no AEC-Q101), same VF/trr performance | Cost-optimized for industrial/commercial use; lacks PPAP documentation and automotive traceability | Select for non-automotive applications where AEC-Q101 is not mandated |
Compared with NRVUA220VT3G and MURA220T3G, the SURA8215T3G-VF01 offers optimal balance of 150 V rating, automotive qualification, and lowest VF in its voltage class - making it preferred for space-constrained 100–120 VAC-derived power rails where thermal headroom and qualification are critical.

FAQ
What is the maximum junction temperature rating for the SURA8215T3G-VF01?
The SURA8215T3G-VF01 has a specified operating junction temperature range of −65 °C to +175 °C. This wide range supports deployment in under-hood automotive environments and high-temperature industrial enclosures. The 175 °C upper limit is validated per AEC-Q101 stress testing, and thermal derating curves in the datasheet confirm usable current capacity down to 1.0 A at TL = 155 °C. SURA8215T3G-VF01 must be mounted on FR-4 PCB with minimum recommended pad size to achieve rated thermal performance.
Is the SURA8215T3G-VF01 AEC-Q101 qualified?
Yes, the SURA8215T3G-VF01 is explicitly AEC-Q101 qualified and PPAP capable, as confirmed in the onsemi datasheet revision history and ordering information table. It carries the "SURA8" prefix denoting automotive-grade manufacturing controls, site-specific traceability, and enhanced reliability screening. SURA8215T3G-VF01 meets all stress tests including HTGB, HTRB, TCT, and ESD per AEC-Q101 Rev D, making it suitable for automotive body control modules and infotainment power supplies.
What is the reverse recovery time (trr) of the SURA8215T3G-VF01 and under what test conditions?
The SURA8215T3G-VF01 has a maximum reverse recovery time (trr) of 35 ns, measured at iF = 1.0 A and di/dt = 50 A/μs, per the onsemi datasheet Electrical Characteristics table. This value is guaranteed across the full operating temperature range and reflects the device's ultra-fast switching capability. SURA8215T3G-VF01 achieves this performance via optimized carrier lifetime control in its glass-passivated junction, directly reducing switching loss in high-frequency converters.
Does the SURA8215T3G-VF01 have a polarity indicator, and how is it marked?
Yes, the SURA8215T3G-VF01 uses a cathode polarity band (a visible stripe) on the banded end of the SMA package to identify Pin 1 (cathode). This marking aligns with JEDEC-standard SMA orientation and is clearly shown in the datasheet mechanical outline and marking diagram. SURA8215T3G-VF01's polarity band ensures correct placement during automated pick-and-place and manual inspection, preventing reverse-bias failure during initial power-up.
What is the thermal resistance (junction-to-lead) for the SURA8215T3G-VF01, and how does it impact PCB layout?
The SURA8215T3G-VF01 has a thermal resistance of 24 °C/W from junction to lead (PsiJL), measured under JEDEC 51 conditions on FR-4 board with minimum recommended pad size. This value means that with 1.5 A average current and 0.77 V forward drop, junction temperature rise above lead temperature is ~28 °C - allowing direct copper pour connection to ground or power planes without additional heatsinking. SURA8215T3G-VF01 layout must follow onsemi's Case 403D footprint and pad recommendations to maintain this thermal performance.
