Product details

Overview

VS-1ENH01HM3/85A from Vishay Semiconductors is an AEC-Q101-qualified ultrafast rectifier in the FRED Pt® family, configured as a single diode with 100 V peak repetitive reverse voltage (V_RRM), 1 A average forward current (I_F(AV)), and 23 ns typical reverse recovery time (t_rr). It delivers low forward voltage drop (0.69 V at 1 A, 150 °C) and low leakage (≤2 μA at rated V_R), enabling high-efficiency PFC and CRM snubber operation in automotive and industrial DC/DC converters.

For engineers reviewing the VS-1ENH01HM3/85A datasheet, VS-1ENH01HM3/85A pinout, VS-1ENH01HM3/85A application, or VS-1ENH01HM3/85A equivalent, key selection criteria include its DO-220AA (SMP) package compatibility with automated placement, 175 °C maximum junction temperature, MSL Level 1 moisture sensitivity, and verified performance under high dI/dt (200 A/μs) and elevated temperature (125–150 °C) conditions.

Technical Context

This device implements a planar ultrafast recovery structure optimized for minimal stored charge (Q_rr = 10 nC typ. at 25 °C) and fast soft recovery behavior, critical for reducing switching losses and EMI in high-frequency hard-switched topologies. Its low junction capacitance (8 pF at 200 V) and controlled reverse recovery waveform support stable operation in resonant and quasi-resonant converters.

The SMP (DO-220AA) package provides thermal resistance of 7 °C/W (junction-to-mount, infinite heatsink) and enables compact layout in space-constrained automotive modules. The matte tin-plated leads meet J-STD-002 solderability and JESD 201 Class 2 whisker resistance requirements, supporting lead-free reflow up to 260 °C peak.

Equivalent & Alternatives

The following parts are listed as comparable options for similar ultrafast rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay VS-1ENH01HM3/84A	Same die, identical electrical specs; differs only in packaging - 7" tape/reel (3000 pcs) vs. 13" tape/reel (10,000 pcs).	No functional difference; suitable for same applications but targeted at lower-volume prototyping or small-batch production.	Select /84A for evaluation or pilot runs; /85A preferred for high-volume manufacturing due to larger reel size and lower handling cost per unit.
ON Semiconductor NUP2114MR6T1G	Lower V_RRM (80 V), higher t_rr (35 ns), not AEC-Q101 qualified; TO-277 package (larger footprint, higher R_thJA).	Limited to non-automotive, lower-voltage (<80 V) DC/DC designs; unsuitable for PFC or under-hood use.	Only consider if V_RRM margin is sufficient and AEC-Q101 is not required; verify thermal performance with R_thJA = 120 °C/W.

Compared with VS-1ENH01HM3/84A, the /85A offers identical performance with optimized logistics for volume production; versus NUP2114MR6T1G, it provides superior voltage rating, faster recovery, automotive qualification, and lower thermal resistance - making it the preferred choice for demanding PFC and automotive applications.

FAQ

What is the maximum junction temperature rating for the VS-1ENH01HM3/85A?

The VS-1ENH01HM3/85A has a maximum junction temperature (T_J(max)) of 175 °C, validated per AEC-Q101 stress testing. This rating allows reliable operation in under-hood automotive environments and high-ambient industrial settings. Derating curves in the datasheet show allowable case temperature versus average forward current, with full 1 A rating maintained up to T_C = 168 °C. Thermal design must account for R_thJM = 7 °C/W (typ.) to ensure T_J remains within limit under actual power dissipation.

Is the VS-1ENH01HM3/85A pin-compatible with other SMP (DO-220AA) diodes?

Yes, the VS-1ENH01HM3/85A uses the standard SMP (DO-220AA) footprint with anode and cathode terminals in fixed positions per JEDEC outline MO-295. Its pinout matches all Vishay eSMP® series diodes in the same package, including VS-1ENH02HM3/85A and VS-1ENH01HM3/84A. Mechanical dimensions, pad layout, and polarity marking (cathode band) are identical, enabling direct PCB reuse across variants with matching voltage/current ratings.

Does the VS-1ENH01HM3/85A meet automotive qualification standards?

Yes, the VS-1ENH01HM3/85A is explicitly AEC-Q101 qualified, as confirmed in the Vishay datasheet (Document Number: 96544, Revision: 24-Oct-2022). This qualification covers stress tests including high-temperature operating life (HTOL), temperature cycling (TC), and unbiased highly accelerated stress test (UHAST), ensuring reliability for automotive powertrain and body electronics applications. The "H" in the part number denotes AEC-Q101 qualification.

What is the reverse recovery time specification for the VS-1ENH01HM3/85A at elevated temperature?

The VS-1ENH01HM3/85A exhibits a reverse recovery time (t_rr) of 22 ns at T_J = 125 °C, measured under I_F = 1 A, dI/dt = 200 A/μs, and V_R = 100 V. This value is documented in the Dynamic Recovery Characteristics table of the official datasheet. At 25 °C, t_rr is 14 ns under the same conditions, confirming stable ultrafast performance across the full operating temperature range.

How does the forward voltage of the VS-1ENH01HM3/85A vary with temperature and current?

The VS-1ENH01HM3/85A forward voltage (V_F) is specified as 0.69 V (typ.) at I_F = 1 A and T_J = 150 °C, and 0.86 V (typ.) at I_F = 1 A and T_J = 25 °C. This negative temperature coefficient means V_F decreases as junction temperature increases - a characteristic of silicon planar diodes that improves thermal stability in parallel configurations. The datasheet includes Fig. 1 showing full V_F vs. I_F curves across -40 °C to 175 °C.
