Product details
Overview
SMA5J36A-E3/61 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for high-energy surge protection on power and signal lines. It features a 36 V stand-off voltage (VWM), 40.0–44.2 V breakdown voltage (VBR) at 1 mA, 500 W peak pulse power (10/1000 μs), 8.6 A peak pulse current (IPPM), and clamps transients to ≤58.1 V. It is widely used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the SMA5J36A-E3/61 datasheet, SMA5J36A-E3/61 pinout, SMA5J36A-E3/61 application, or SMA5J36A-E3/61 equivalent, key selection criteria include unidirectional polarity, 500 W surge rating, 36 V working voltage, RoHS-compliant matte tin plating, and AEC-Q101 qualification availability via HE3 suffix variants.
Technical Context
This TVS diode operates as a clamping device that enters avalanche conduction when reverse voltage exceeds its breakdown threshold (40.0–44.2 V), limiting transient energy to protected downstream circuitry. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time (<1.0 ps), critical for suppressing ESD and inductive switching spikes.
Thermal performance is defined by RθJA = 80 °C/W and RθJL = 25 °C/W, with maximum junction temperature of +150 °C. It is rated for non-repetitive 8.3 ms half-sine surge current up to 40 A (IFSM) and meets J-STD-020 MSL Level 1 (260 °C reflow peak).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC bias range. |
| VBR min/max | 40.0 V / 44.2 V at IT = 1 mA - Confirmed breakdown window ensures reliable turn-on without premature conduction. |
| VC @ IPPM | ≤58.1 V at 8.6 A - Clamping voltage under 10/1000 μs surge; determines maximum stress on protected IC or MOSFET. |
| PPPM | 500 W - Peak pulse power handling capability; enables robust protection against IEC 61000-4-5 Level 4 surges. |
| ID @ VWM | ≤1.0 μA - Ultra-low reverse leakage preserves efficiency in low-power sensor or battery-backed circuits. |
| TJ max | +150 °C - Enables operation in under-hood automotive or industrial environments without thermal derating. |
| Package | SMA (DO-214AC) - Surface-mount footprint compatible with automated assembly; 0.208" × 0.157" body with cathode band marking. |
Pinout & Package
SMA5J36A-E3/61 uses the standard SMA (DO-214AC) surface-mount package: two-terminal, unidirectional configuration with cathode indicated by a visible band on the case. The device has no internal pins-terminals are the anode and cathode leads formed from the molded leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; connected to ground or low-side reference in typical TVS placement. | Provides return path during clamping; must be routed with low-inductance trace to minimize overshoot. |
| Cathode (banded end) | Protected line connection point; reverse-biased during normal operation. | Connected to the line being protected (e.g., 36 V rail or sensor input); clamps to anode when overvoltage occurs. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling and humidity exposure. |
| Low incremental surge resistance | Minimizes clamping voltage rise under high di/dt events, improving protection margin for sensitive gate drivers. |
| MSL Level 1 (260 °C) | Enables single-reflow assembly without moisture-related popcorning; eliminates pre-bake requirement. |
| RoHS-compliant matte tin plating | Meets J-STD-002 and JESD 22-B102 solderability standards; supports lead-free reflow and whisker resistance Class 2. |
| 500 W peak pulse rating | Supports IEC 61000-4-5 surge immunity up to 4 kV (line-earth) in properly designed PCB layouts. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |

IC Role / Device Role / Timing Role: Primary clamping device on DC input side, upstream of DC-DC converters and hot-swap controllers. Use Value: 500 W rating handles repetitive 10/1000 μs surges per IEC 61000-4-5; 80 °C/W RθJA allows thermal design within 75 °C ambient. |
Use Scenario: Protecting USB-C PD power delivery paths in portable medical monitors and handheld test equipment. IC Role / Device Role / Timing Role: Unidirectional TVS on VBUS line to suppress ESD (IEC 61000-4-2 ±15 kV contact) and hot-plug transients. Use Value: 36 V VWM avoids false triggering during 20 V PD negotiation; 58.1 V VC ensures safe clamp below 60 V absolute maximum ratings of PD controllers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J36A-M3/61 | Halogen-free, RoHS-compliant variant with identical electrical specs and SMA package; same 36 V VWM and 500 W PPPM. | No functional difference; selected where halogen-free compliance is mandated by OEM or regional environmental policy. | Choose SMA5J36A-M3/61 when halogen-free material declaration is required for final product certification. |
| SMA5J36CA-E3/61 | Bidirectional version with same VWM (36 V), VBR (40.0–44.2 V), and PPPM (500 W), but symmetrical clamping in both polarities. | Required only for AC-coupled or floating signal lines subject to bipolar transients (e.g., RS-485, CAN FD differential pairs). | Select SMA5J36CA-E3/61 only if bidirectional protection is needed; SMA5J36A-E3/61 is optimal for DC rails with defined polarity. |
Compared with SMA5J36A-M3/61, the -E3/61 offers standard RoHS compliance without halogen-free constraint; compared with SMA5J36CA-E3/61, it provides lower capacitance and tighter leakage in unidirectional DC applications, improving efficiency and noise margin.
