Product details
Overview
ESH1DHE3_A/H from Vishay General Semiconductor is an AEC-Q101-qualified surface-mount ultrafast plastic rectifier diode in SMA (DO-214AC) package, rated for 200 V repetitive peak reverse voltage, 1.0 A average forward current, and 25 ns reverse recovery time. It delivers low forward voltage (0.90 V at 1 A), operates up to 175 °C junction temperature, and serves as a freewheeling or secondary rectifier in high-frequency DC/DC converters under automotive thermal stress.
For engineers reviewing the ESH1DHE3_A/H datasheet, ESH1DHE3_A/H pinout, ESH1DHE3_A/H application, or ESH1DHE3_A/H equivalent, key selection criteria include its AEC-Q101 qualification, 25 ns trr performance at 100 °C, TJ = 175 °C rating, RoHS-compliant matte tin terminals, and compatibility with automated SMT placement on PCBs with 5.0 mm × 5.0 mm copper pads.
Technical Context
The ESH1DHE3_A/H is a single-die, single-anode/cathode ultrafast recovery rectifier optimized for high-efficiency switching power supplies. Its glass-passivated junction ensures stable leakage behavior up to 125 °C (IR = 25 µA), while its 25 pF junction capacitance at 4.0 V supports high-frequency operation without excessive capacitive loading.
Designed for automotive-grade reliability, the device meets MSL Level 1 per J-STD-020 with 260 °C lead-free reflow peak, and its thermal resistance RθJL = 30 °C/W enables robust thermal management when mounted on standard PCB land patterns. The cathode band marking provides unambiguous polarity identification during assembly.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R02UF | Same SMA package, 200 V VRRM, but trr = 35 ns (typ) at 100 °C; VF = 0.95 V @ 1 A; not AEC-Q101 qualified. | Suitable for industrial/commercial DC/DC where automotive qualification is unnecessary; higher trr increases switching loss at >150 kHz. | Select when cost sensitivity outweighs AEC-Q101 requirement and switching frequency remains ≤120 kHz. |
| ON Semi MUR120E | SMA package, 200 V VRRM, trr = 35 ns (max), VF = 0.97 V @ 1 A, TJ max = 175 °C, but no AEC-Q101 certification or MSL Level 1 data published. | Acceptable for non-automotive consumer power supplies; lacks documented reflow robustness and automotive stress validation. | Choose only for cost-driven commercial designs where full automotive qualification and lead-free process assurance are not mandated. |
Compared with STTH1R02UF and MUR120E, the ESH1DHE3_A/H uniquely combines AEC-Q101 qualification, 25 ns trr at 100 °C, and MSL Level 1 compliance-making it the only option among the three validated for under-hood automotive use with verified 260 °C reflow survivability and zero-defect field reliability targets.

FAQ
What is the maximum junction temperature rating for ESH1DHE3_A/H?
The ESH1DHE3_A/H has a maximum junction temperature (TJ max.) of 175 °C, enabling operation in high-ambient environments such as automotive engine compartments or sealed industrial enclosures. This rating is validated per the Vishay datasheet revision 08-Apr-2020 and applies under specified thermal conditions with appropriate PCB copper area. The ESH1DHE3_A/H maintains electrical integrity and reliability up to this limit without parameter degradation.
Is ESH1DHE3_A/H compatible with lead-free reflow soldering processes?
Yes, the ESH1DHE3_A/H meets MSL Level 1 per J-STD-020 and is qualified for peak reflow temperatures up to 260 °C, making it fully compatible with standard lead-free soldering profiles. Its matte tin-plated leads comply with JESD 22-B102 whisker testing (Class 2), and the package withstands thermal shock without delamination. This ensures reliable assembly for ESH1DHE3_A/H in high-volume SMT lines without preconditioning.
Does ESH1DHE3_A/H have AEC-Q101 qualification, and what does that cover?
Yes, ESH1DHE3_A/H is explicitly AEC-Q101 qualified, as confirmed by the "HE3" suffix and documentation in Vishay's 88890 datasheet. This qualification covers stress tests including temperature cycling, high-temperature operating life, unbiased highly accelerated stress test (uHAST), and mechanical shock-validating suitability for automotive powertrain and body electronics. The ESH1DHE3_A/H is certified for zero-defect field reliability in automotive applications.
What is the reverse recovery time (trr) of ESH1DHE3_A/H, and how is it measured?
The ESH1DHE3_A/H has a maximum reverse recovery time (trr) of 25 ns, measured under JEDEC conditions: IF = 0.5 A, IR = 1 A, and Irr = 0.25 A. Typical trr remains 25 ns at 25 °C and rises to 35 ns at 100 °C. This value is critical for minimizing switching losses in high-frequency DC/DC converters. The ESH1DHE3_A/H achieves this performance via optimized carrier lifetime control in its ultrafast silicon junction.
What packaging and reel options are available for ESH1DHE3_A/H?
ESH1DHE3_A/H is supplied in 7" diameter plastic tape and reel with 1800 units per reel (package code H).
