Product details
Overview
SE70PJ-M3/86A from Vishay General Semiconductor is a surface-mount, single-diode ESD-capable rectifier in SMPC (TO-277A) package, rated for 600 V repetitive peak reverse voltage (VRRM), 7.0 A average forward current (IF(AV)), and 120 A non-repetitive surge current (IFSM). It delivers low forward voltage drop (0.87 V at 7.0 A, 125 °C) and operates up to 175 °C junction temperature, supporting power line polarity protection in automotive and industrial DC power rails.
For engineers reviewing the SE70PJ-M3/86A datasheet, SE70PJ-M3/86A pinout, SE70PJ-M3/86A application, or SE70PJ-M3/86A equivalent, key selection criteria include its 600 V VRRM, MSL Level 1 moisture sensitivity, AEC-Q101 qualification path (via HM3 suffix), 2.6 μs typical reverse recovery time, and halogen-free RoHS-compliant construction.
Technical Context
This device is a planar-junction, silicon epitaxial rectifier optimized for fast switching and high surge robustness. Its oxide planar chip junction enables stable reverse leakage (<10 μA at rated VR, 25 °C) and low capacitance (76 pF at 4.0 V, 1 MHz), while the SMPC package provides thermal resistance of 5 °C/W (junction-to-mount) on 2 oz. FR4 PCB.
Designed for unidirectional DC power conditioning, it supports automated placement with 1.1 mm profile and meets JESD 201 Class 1A whisker testing. The cathode-band-marked TO-277A outline ensures consistent orientation during assembly and thermal management via direct PCB copper pad contact.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum reverse blocking capability for 24–48 V DC bus protection with safety margin against transients. |
| IF(AV) | 7.0 A - Continuous forward current rating at 175 °C TJ, enabling use in high-current power supply outputs without forced cooling. |
| VF @ 7.0 A, 125 °C | 0.87 V - Low conduction loss reduces power dissipation and thermal stress in compact layouts. |
| trr | 2.6 μs - Fast recovery minimizes switching losses in medium-frequency rectification (e.g., <100 kHz SMPS outputs). |
| CJ | 76 pF @ 4 V, 1 MHz - Low junction capacitance limits capacitive coupling noise in sensitive analog or communication circuits. |
| RθJM | 5 °C/W - Enables efficient heat transfer to PCB copper, supporting >5 W power dissipation with proper pad design. |
| ESD Rating | >8 kV HBM (Class H3B) - Robust electrostatic discharge immunity simplifies handling and improves field reliability in automotive assembly lines. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay SE70PG-M3/86A | 400 V VRRM, same IF(AV), trr, and package; lower reverse voltage rating. | Suitable only for ≤400 V systems (e.g., 24 V/48 V industrial rails); not recommended for 600 V solar strings. | Select when system max reverse voltage is ≤400 V and cost optimization is prioritized over margin. |
| ON Semiconductor MUR760G | 600 V VRRM, 7 A IF(AV), but TO-220AC package (higher profile, through-hole), 50 ns trr. | Requires PCB through-hole mounting and larger heatsinking; incompatible with automated SMT lines. | Choose only if legacy through-hole design or higher surge tolerance (150 A IFSM) is required and board real estate is unconstrained. |
Compared with SE70PG-M3/86A and MUR760G, the SE70PJ-M3/86A uniquely combines 600 V blocking, SMT-compatible SMPC packaging, and automotive-grade ESD robustness-enabling compact, high-reliability, and assembly-optimized designs where both voltage margin and manufacturability matter.

FAQ
What is the maximum junction temperature rating for the SE70PJ-M3/86A?
The SE70PJ-M3/86A has a maximum operating junction temperature (TJ) of +175 °C, verified per Vishay's qualification testing and documented in the primary characteristics table. This rating allows the SE70PJ-M3/86A to operate reliably in under-hood automotive environments and high-ambient industrial enclosures without derating below full 7.0 A current until mount temperature exceeds 125 °C.
Is the SE70PJ-M3/86A AEC-Q101 qualified?
The SE70PJ-M3/86A itself is commercial-grade (M3 suffix), but Vishay offers the functionally identical SE70PJHM3_A/H variant with AEC-Q101 qualification. The SE70PJ-M3/86A shares the same die, SMPC package, and process flow-making it qualification-ready for automotive programs that require AEC-Q101 compliance with minimal revalidation effort.
What does the "86A" in SE70PJ-M3/86A indicate?
The "86A" is Vishay's preferred package code denoting 7-inch diameter plastic tape-and-reel packaging with 1500 units per reel. It specifies physical delivery format-not electrical or thermal performance-and is compatible with standard SMT pick-and-place equipment using EIA-481-D compliant feeders.
How does the SE70PJ-M3/86A compare to standard Schottky rectifiers in terms of forward voltage?
The SE70PJ-M3/86A is a silicon planar rectifier-not a Schottky-so its 0.87 V VF at 7.0 A and 125 °C is higher than typical Schottky devices, but it offers superior reverse leakage (<10 μA), higher VRRM (600 V), and no soft recovery issues. The SE70PJ-M3/86A trades marginal VF increase for robustness in high-voltage, high-temperature, and high-reliability applications where Schottkys would fail.
Can the SE70PJ-M3/86A be used in place of a TO-220 rectifier like the MUR760G?
No-the SE70PJ-M3/86A uses SMPC (TO-277A) surface-mount packaging, while the MUR760G uses TO-220AC through-hole packaging. They are not pin-compatible or footprint-compatible. Substituting the SE70PJ-M3/86A requires PCB redesign for SMT pads and thermal relief; however, its 5 °C/W RθJM can deliver better thermal performance than TO-220 when mounted on adequate copper area.
