Product details
Overview
VS-2ENH02HM3/85A from Vishay Semiconductors is an AEC-Q101-qualified ultrafast rectifier in SMP (DO-220AA) package, rated for 200 V peak reverse voltage and 2 A average forward current, with 23 ns typical reverse recovery time and 0.79 V forward voltage at 2 A and 150 °C - deployed in automotive PFC stages and high-frequency snubber circuits.
For engineers reviewing the VS-2ENH02HM3/85A datasheet, VS-2ENH02HM3/85A pinout, VS-2ENH02HM3/85A application, or VS-2ENH02HM3/85A equivalent, key selection criteria include its 200 V blocking capability, low Qrr (15 nC typ. at 25 °C), MSL Level 1 rating, 1.0 mm profile for space-constrained layouts, and AEC-Q101 qualification for under-hood automotive use.
Technical Context
This device belongs to Vishay's FRED Pt® eSMP® series of ultrafast recovery diodes optimized for high-efficiency switching converters. Its silicon process delivers tightly controlled trr (23 ns typ.) and low Qrr (15–37 nC across temperature), enabling reduced switching losses in CRM and transition-mode PFC topologies.
The SMP (DO-220AA) package supports automated placement and features matte tin-plated leads compliant with J-STD-002 and JESD 201 Class 2 whisker testing. Polarity is marked by a cathode band, and thermal resistance junction-to-mount is 7–9 °C/W under infinite heatsink conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Reverse Voltage (VR) | 200 V - supports input rectification in 100–120 VAC PFC front-ends with margin against line surges. |
| Average Forward Current (IF(AV)) | 2 A at TC = 158 °C - enables compact thermal design in surface-mount DC/DC converters with minimal copper area. |
| Forward Voltage (VF) | 0.79 V at IF = 2 A, TJ = 150 °C - reduces conduction loss and improves system efficiency in high-duty-cycle operation. |
| Reverse Recovery Time (trr) | 23 ns typ. at IF = 1.0 A, dIF/dt = 100 A/μs - minimizes switching node ringing and EMI in >100 kHz power stages. |
| Reverse Leakage Current (IR) | 2 μA max. at rated VR, 25 °C - ensures low standby loss in battery-backed or energy-harvesting auxiliary rails. |
| Junction Capacitance (CT) | 8 pF at VR = 200 V - limits capacitive turn-on loss and aids zero-voltage switching (ZVS) compatibility. |
| Operating Temperature Range | −55 °C to +175 °C - validated for under-hood automotive environments per AEC-Q101 stress test requirements. |
Pinout & Package
SMP (DO-220AA) package: surface-mount, single-diode configuration, 1.0 mm typical height, cathode marked by color band, matte tin-plated leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry terminal | Connected to source-side of switching node in freewheeling path or PFC boost diode position. |
| Cathode | Forward current exit terminal | Marked by color band; ties to output rail or switch node - defines polarity for correct PCB layout orientation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and UHAST - suitable for engine control and ADAS power supplies. |
| Ultrafast recovery (trr = 23 ns) | Enables high-frequency operation (>300 kHz) without excessive switching loss or voltage overshoot in CRM PFC controllers. |
| Low Qrr (15 nC typ.) | Reduces stored charge dissipation during turn-off, lowering EMI generation and improving light-load efficiency in discontinuous conduction mode. |
| MSL Level 1 (260 °C peak) | Supports standard lead-free reflow profiles without preconditioning - eliminates moisture sensitivity handling overhead in SMT lines. |
| Halogen-free, RoHS-compliant (M3) | Meets EU Directive 2011/65/EU and JEDEC JS709C - required for automotive OEM supply chain compliance. |
Applications
| Automotive On-Board Charger (OBC) PFC Stage | Industrial AC/DC Adapter Snubber Circuit |
|---|---|
Use Scenario: High-efficiency 3.3 kW two-stage OBC with interleaved boost PFC operating at 100–300 kHz. IC Role / Device Role / Timing Role: Primary boost rectifier handling 2 A average current at 200 V blocking, placed directly after boost inductor. Use Value: Low VF (0.79 V) and fast trr (23 ns) reduce conduction and switching losses, enabling >98% PFC efficiency at full load. |
Use Scenario: 48 V telecom rectifier with RCD snubber network protecting MOSFETs in flyback or forward converters. IC Role / Device Role / Timing Role: Snubber diode clamping voltage spikes during MOSFET turn-off; operates in unidirectional pulse mode. Use Value: Low Qrr (15 nC) prevents reverse recovery current from adding to snubber capacitor discharge current, stabilizing clamp voltage. |
| Server PSU Active Clamp Forward Converter | EV Battery Management System (BMS) Isolation Supply |
Use Scenario: 1.5 kW server PSU using active clamp forward topology with synchronous rectification on secondary side. IC Role / Device Role / Timing Role: Freewheeling diode in clamp circuit, conducting only during reset phase with <100 ns pulse width. Use Value: 175 °C max junction temperature and low CT (8 pF) ensure stable clamp timing and prevent thermal runaway during burst-mode operation. |
Use Scenario: Isolated 5 V/1 W auxiliary supply powering isolated CAN transceivers and ADC references in high-voltage BMS stacks. IC Role / Device Role / Timing Role: Output rectifier in miniature flyback transformer secondary, operating at 250 kHz with 2 A peak current. Use Value: AEC-Q101 qualification and −55 °C to +175 °C range guarantee reliable startup and operation across vehicle thermal zones, including battery pack interior. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R02DJF | 200 V, 2 A, trr = 25 ns, TO-277A package (larger footprint, 1.8 mm height) | Higher thermal resistance (RthJA ≈ 130 °C/W vs. 107 °C/W), no AEC-Q101 qualification | Preferred where board space allows larger package and automotive qualification is not required. |
| ON Semiconductor NRVBFS2200T3G | 200 V, 2 A, trr = 20 ns, same SMP (DO-220AA) package, AEC-Q101 qualified | Lower VF (0.75 V typ. at 2 A), but higher IR (5 μA max.) and no M3 halogen-free marking | Selected when lowest forward drop is prioritized over leakage or environmental compliance. |
Compared with STTH2R02DJF and NRVBFS2200T3G, VS-2ENH02HM3/85A uniquely balances AEC-Q101 qualification, M3 environmental compliance, and 23 ns trr in the industry's smallest 1.0 mm-profile SMP package - making it optimal for space- and reliability-critical automotive and industrial power modules.

FAQ
What is the maximum junction temperature rating for VS-2ENH02HM3/85A?
The VS-2ENH02HM3/85A has a maximum junction temperature (TJ) of +175 °C, verified per AEC-Q101 stress testing and supported by its thermal resistance junction-to-mount of 7–9 °C/W. This rating allows the VS-2ENH02HM3/85A to operate reliably in under-hood automotive environments and high-ambient industrial enclosures without derating at full current up to TC = 158 °C.
Is VS-2ENH02HM3/85A pin-compatible with VS-2ENH01HM3/85A?
Yes, VS-2ENH02HM3/85A shares identical SMP (DO-220AA) package dimensions, pinout, and mounting pad layout with VS-2ENH01HM3/85A. The only functional difference is the peak reverse voltage rating: VS-2ENH02HM3/85A is rated for 200 V versus 100 V for VS-2ENH01HM3/85A. Both devices use the same anode/cathode terminal assignment and marking convention.
Does VS-2ENH02HM3/85A meet automotive qualification standards?
Yes, VS-2ENH02HM3/85A is AEC-Q101 qualified, having passed all stress tests including temperature cycling, high-temperature reverse bias (HTRB), and unbiased highly accelerated stress test (UHAST). This qualification confirms its suitability for automotive power electronics such as on-board chargers, DC/DC converters, and body control modules.
What is the reverse recovery charge (Qrr) specification for VS-2ENH02HM3/85A at 125 °C?
At TJ = 125 °C, the VS-2ENH02HM3/85A exhibits a typical reverse recovery charge (Qrr) of 37 nC, measured under standard conditions (IF = 2 A, dIF/dt = 200 A/μs, VR = 100 V). This value is critical for estimating switching loss in CRM PFC designs and must be used in loss calculations at elevated temperatures.
What packaging option does VS-2ENH02HM3/85A use, and what is its minimum order quantity?
VS-2ENH02HM3/85A is supplied in 13-inch diameter plastic tape and reel packaging (package code "85A"), with a minimum order quantity of 10,000 units. This packaging supports high-speed automated placement and complies with J-STD-020 MSL Level 1 handling requirements, eliminating the need for baking prior to reflow.
