Product details
Overview
SUM85N15-19-E3 from Vishay Siliconix is an N-channel TrenchFET power MOSFET rated for 150 V drain-source breakdown, 85 A continuous drain current at TC = 25 °C, and 0.019 Ω rDS(on) at VGS = 10 V - deployed as a primary-side switch in automotive EPS/ABS systems and high-efficiency DC/DC converters.
For engineers reviewing the SUM85N15-19-E3 datasheet, SUM85N15-19-E3 pinout, SUM85N15-19-E3 application, or SUM85N15-19-E3 equivalent, key selection criteria include its 175 °C junction rating, 0.4 °C/W junction-to-case thermal resistance, 100% Rg-tested gate robustness, TO-263 package footprint, and avalanche energy capability of 125 mJ (repetitive).
Technical Context
This device uses trench-gate silicon technology to achieve low on-resistance with high voltage blocking. Its SOA curve supports single-pulse operation up to 150 V and 85 A, and it features a built-in source-drain diode with 1.0–1.5 V forward voltage at 85 A and 130–200 ns reverse recovery time.
The MOSFET operates with a gate-threshold voltage of 2–4 V and exhibits 4750 pF input capacitance, 530 pF output capacitance, and 220 pF reverse transfer capacitance at VGS = 0 V and VDS = 25 V - enabling fast switching in hard-switched topologies while maintaining EMI control via controlled Qgd (26 nC) and Qgs (21 nC).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| V(BR)DSS | 150 V - supports primary-side switching in 48 V–100 V bus DC/DC and motor drive inverters without derating. |
| rDS(on) | 0.019 Ω @ VGS = 10 V, ID = 30 A - delivers ≤1.5 W conduction loss at 85 A, enabling compact thermal design. |
| ID (continuous) | 85 A @ TC = 25 °C - package-limited current suitable for high-power automotive loads like EPS actuators. |
| RthJC | 0.4 °C/W - enables direct heatsink mounting for efficient power dissipation in space-constrained modules. |
| EAS (repetitive) | 125 mJ @ L = 0.1 mH - sustains unclamped inductive switching stress in motor drive freewheeling paths. |
| Qg / Qgd | 76–110 nC total gate charge, 26 nC gate-drain charge - balances switching speed and gate drive loss in 100–500 kHz converters. |
| TJ range | −55 to +175 °C - qualified for under-hood automotive environments per AEC-Q101 requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP85NF15 | Same V(BR)DSS (150 V), higher rDS(on) = 0.022 Ω, lower ID = 80 A, TO-220 package | Lacks TO-263 thermal performance; unsuitable for high-density automotive modules | Choose when board-level heatsinking is available and leaded through-hole assembly is preferred. |
| IRFP4668PBF | Higher V(BR)DSS = 170 V, rDS(on) = 0.018 Ω, same TO-263, but no 100% Rg test or AEC-Q101 qualification | Not automotive-qualified; used in industrial UPS and solar inverters where extended voltage margin is critical | Choose when 170 V blocking is required and automotive temperature cycling validation is not mandated. |
Compared with STP85NF15 and IRFP4668PBF, the SUM85N15-19-E3 uniquely combines AEC-Q101 qualification, 100% Rg testing, and 0.4 °C/W RthJC in a lead-free TO-263 - making it the only option validated for under-hood EPS/ABS deployment with minimal thermal margin.

FAQ
What is the maximum continuous drain current rating for SUM85N15-19-E3 at 125 °C case temperature?
The SUM85N15-19-E3 supports 50 A continuous drain current at TC = 125 °C, as specified in the Absolute Maximum Ratings table. This derated value reflects thermal limitations of the TO-263 package under elevated ambient conditions and must be verified against actual PCB layout and heatsinking in the final design. The SUM85N15-19-E3 datasheet confirms this limit applies to steady-state operation with proper thermal management.
Does SUM85N15-19-E3 have AEC-Q101 qualification for automotive use?
Yes, the SUM85N15-19-E3 is AEC-Q101 qualified for automotive applications, including Electric Power Steering and Anti-lock Braking Systems. Its −55 to +175 °C operating junction temperature range, 100% Rg testing, and repetitive avalanche rating align with AEC-Q101 stress test requirements. The SUM85N15-19-E3 product summary explicitly cites automotive use in its Applications section.
What is the gate threshold voltage range for SUM85N15-19-E3?
The gate-threshold voltage (VGS(th)) for SUM85N15-19-E3 is specified as 2–4 V at VDS = VGS and ID = 250 µA. This range ensures reliable turn-on with standard 5 V or 10 V gate drivers while maintaining noise immunity in noisy automotive environments. The SUM85N15-19-E3 datasheet lists this parameter in the Static Characteristics table under Specifications.
Can SUM85N15-19-E3 replace older Vishay SUM85N15-19 in existing designs?
Yes, SUM85N15-19-E3 is a direct lead-free replacement for SUM85N15-19, sharing identical electrical specifications, TO-263 package dimensions, and pinout. The "E3" suffix denotes matte tin lead-free termination compatible with Pb-free reflow profiles. No layout or schematic changes are needed when migrating from SUM85N15-19 to SUM85N15-19-E3.
What is the typical reverse recovery charge (Qrr) of the intrinsic body diode in SUM85N15-19-E3?
The SUM85N15-19-E3 body diode has a reverse recovery charge (Qrr) of 0.52–1.2 µC, measured at IF = 50 A, di/dt = 100 A/µs, and TJ = 25 °C. This value impacts commutation losses in synchronous rectification and freewheeling applications. The SUM85N15-19-E3 datasheet specifies Qrr in the Source-Drain Diode Characteristics table.
