Product details
Overview
ESH3CHE3_A/H from Vishay General Semiconductor is a surface-mount ultrafast plastic rectifier diode in SMC (DO-214AB) package, rated for 150 V repetitive peak reverse voltage, 3.0 A average forward current, and 25 ns maximum reverse recovery time. It features glass-passivated junction, AEC-Q101 qualification, and low 0.90 V forward voltage at 3 A - enabling high-efficiency freewheeling and high-frequency rectification in automotive DC/DC converters.
For engineers reviewing the ESH3CHE3_A/H datasheet, ESH3CHE3_A/H pinout, ESH3CHE3_A/H application, or ESH3CHE3_A/H equivalent, key selection criteria include its 150 V VRRM, 175 °C max junction temperature, AEC-Q101 qualification, SMC package thermal resistance (RθJA = 50 °C/W), and 125 A IFSM surge capability - critical for under-hood power conversion reliability.
Technical Context
This device is a single-die, single-anode/cathode silicon PN junction rectifier optimized for fast switching in hard-commutated topologies. Its 25 ns trr (measured at IF = 0.5 A, IR = 1 A, Irr = 0.25 A) and low Qrr (25 nC typical at TJ = 25 °C) minimize switching losses in 100–500 kHz SMPS designs.
The SMC package provides robust thermal performance with RθJL = 15 °C/W to lead and meets MSL Level 1 per J-STD-020 (260 °C peak reflow). Matte tin-plated leads comply with J-STD-002 and JESD 22-B102, and the HE3 suffix confirms AEC-Q101 qualification and JESD 201 Class 2 whisker resistance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S | 600 V VRRM, 3 A IF(AV), 35 ns trr, TO-277 package | Higher voltage rating suits 48 V industrial systems; slower recovery increases switching loss at >150 kHz | Select when higher reverse voltage margin is required and switching frequency is ≤150 kHz |
| ON Semi MUR315 | 150 V VRRM, 3 A IF(AV), 35 ns trr, DO-214AB package, no AEC-Q101 | Same package and voltage rating but lacks automotive qualification and has higher VF (1.15 V) | Acceptable for industrial use where AEC-Q101 is not mandated and lower conduction loss is not critical |
Compared with STTH3L06S and MUR315, ESH3CHE3_A/H delivers superior high-frequency efficiency due to its 25 ns trr and 0.90 V VF, while its AEC-Q101 qualification and 175 °C rating make it the only option validated for under-hood automotive deployment.

FAQ
What is the maximum junction temperature rating for ESH3CHE3_A/H?
The ESH3CHE3_A/H has a maximum junction temperature (TJ(max)) of 175 °C, verified per Vishay's qualification testing and documented in the 84648 datasheet. This rating enables reliable operation in under-hood automotive environments and high-ambient industrial settings without active cooling. The 175 °C limit applies across the full rated current range and is supported by thermal characterization curves in Figure 6 of the ESH3B/C/D datasheet.
Is ESH3CHE3_A/H AEC-Q101 qualified?
Yes, ESH3CHE3_A/H is AEC-Q101 qualified, as confirmed by the "HE3" suffix in its part number and explicitly stated in the "MECHANICAL DATA" and "ELECTRICAL CHARACTERISTICS" sections of Vishay document 84648. This qualification covers stress tests including HTGB, HTRB, TCT, and UHAST, validating suitability for automotive powertrain and chassis applications.
What does the "_A/H" suffix in ESH3CHE3_A/H indicate?
The "_A/H" suffix in ESH3CHE3_A/H specifies packaging and revision: "A" denotes the revision code per Vishay's internal change control, and "H" indicates the preferred package code for 7-inch tape-and-reel delivery (850 units per reel), as defined in the "ORDERING INFORMATION" table of document 84648. This matches the SMC (DO-214AB) physical form factor and AEC-Q101 qualification status.
What is the reverse recovery time (trr) specification for ESH3CHE3_A/H?
The maximum reverse recovery time (trr) for ESH3CHE3_A/H is 25 ns, measured under conditions of IF = 0.5 A, IR = 1 A, and Irr = 0.25 A, per the "ELECTRICAL CHARACTERISTICS" table in Vishay document 84648. Typical trr rises to 40 ns at 3 A forward current and 30 V reverse voltage, reflecting real-world switching behavior in high-current SMPS designs.
Does ESH3CHE3_A/H meet JEDEC moisture sensitivity level requirements?
Yes, ESH3CHE3_A/H meets MSL Level 1 per J-STD-020, with a maximum peak reflow temperature of 260 °C. This is confirmed in the "FEATURES" section of document 84648 and enables standard SMT assembly without pre-baking. The SMC molding compound also complies with UL 94 V-0 flammability rating, supporting safety-critical board-level integration.
