Product details

Overview

SMA5J36-E3/5A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, designed for robust overvoltage protection of DC power rails and signal lines. It features a 36 V stand-off voltage (V_WM), 40.0–44.2 V breakdown voltage (V_BR at 1 mA), 500 W peak pulse power (10/1000 µs), clamping voltage of 58.1 V at 8.6 A, and operates from –55 °C to +150 °C junction temperature.

For engineers reviewing the SMA5J36-E3/5A datasheet, SMA5J36-E3/5A pinout, SMA5J36-E3/5A application, or SMA5J36-E3/5A equivalent, key selection criteria include clamping performance under 10/1000 µs surge, thermal resistance (R_θJA = 80 °C/W), AEC-Q101 qualification status, RoHS compliance (E3 suffix), and compatibility with automated SMT placement on standard 5.0 mm × 5.0 mm copper pads.

Technical Context

This TVS diode functions as a voltage-clamped shunt protector, conducting only when reverse voltage exceeds V_BR, thereby diverting transient energy away from downstream ICs or MOSFETs. Its glass-passivated junction ensures stable leakage (<1.0 µA at V_WM) and fast response time (<1 ns), critical for protecting sensitive inputs against ESD and inductive switching spikes.

The device is rated for non-repetitive 8.3 ms half-sine surge current up to 40 A (I_FSM) and exhibits low incremental surge resistance, enabling effective clamping even during high-current transients. Its DO-214AC package supports surface-mount assembly and meets MSL level 1 (260 °C reflow peak).

Key Specifications

Parameter	Value and Actual Design Meaning
V_WM	36 V - Maximum continuous reverse operating voltage before conduction begins; defines safe DC rail margin.
V_BR (min/max)	40.0 V / 44.2 V at 1 mA - Ensures reliable triggering above system nominal voltage while avoiding false trips.
V_C @ I_PPM	58.1 V at 8.6 A - Clamping voltage during 10/1000 µs surge; determines maximum stress on protected circuitry.
P_PPM	500 W - Peak pulse power handling capability; defines survivability under standardized lightning/surge waveforms.
I_FSM	40 A - Single half-sine surge current rating (8.3 ms); validates robustness against motor-switching or relay-bounce events.
T_J max	+150 °C - Maximum junction temperature; enables use in under-hood automotive or industrial environments.
R_θJA	80 °C/W - Thermal resistance junction-to-ambient; informs PCB pad design and derating above 25 °C ambient.

Equivalent & Alternatives

The following parts are listed as comparable options for similar transient suppression applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SMA5J36AHE3/5A	AEC-Q101 qualified (HE3 suffix); identical electrical specs and package.	Required for automotive-grade designs requiring full qualification documentation and traceability.	Select HE3 version when automotive PPAP or qualification reporting is mandated.
SMCJ36A-E3/57T	DO-214AB (SMC) package; higher P_PPM = 1500 W; same V_WM/V_BR/V_C ratings.	Better suited for higher-energy transients where board space allows larger footprint.	Choose SMCJ36A-E3/57T when surge energy exceeds 500 W but V_C and layout constraints permit larger package.

Compared with SMA5J36-E3/5A, the HE3 variant adds formal AEC-Q101 certification without electrical change, while SMCJ36A-E3/57T trades smaller size for 3× higher surge capacity-enabling design flexibility across cost, space, and ruggedness requirements.

FAQ

What is the clamping voltage of the SMA5J36-E3/5A under a 10/1000 µs surge?

The SMA5J36-E3/5A has a maximum clamping voltage (V_C) of 58.1 V at 8.6 A peak pulse current (I_PPM) under a 10/1000 µs waveform. This value is measured per JEDEC/ANSI standards and defines the upper voltage limit imposed on protected circuitry during standardized surge events. The SMA5J36-E3/5A maintains this clamping performance across its specified operating temperature range.

Is the SMA5J36-E3/5A AEC-Q101 qualified?

No, the SMA5J36-E3/5A is not AEC-Q101 qualified. It carries the E3 suffix, indicating RoHS compliance and commercial-grade qualification. For AEC-Q101 compliance, the correct part is SMA5J36AHE3/5A (HE3 suffix). Both share identical electrical parameters and DO-214AC packaging, but only the HE3 version undergoes full automotive qualification testing and reporting.

What is the standoff voltage and breakdown voltage range for the SMA5J36-E3/5A?

The SMA5J36-E3/5A has a standoff voltage (V_WM) of 36 V and a breakdown voltage (V_BR) range of 40.0 V to 44.2 V at 1 mA test current. This V_BR window ensures reliable turn-on above normal operating voltage while maintaining margin against nuisance conduction due to ripple or tolerance stack-up. The SMA5J36-E3/5A datasheet specifies these values at T_A = 25 °C with derating above ambient.

What package type does the SMA5J36-E3/5A use, and what are its mounting requirements?

The SMA5J36-E3/5A uses the DO-214AC (SMA) surface-mount package with matte tin-plated leads. It requires mounting on minimum recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal for thermal and surge performance. The SMA5J36-E3/5A is MSL Level 1 and supports standard 260 °C reflow profiles without pre-baking.

How does the SMA5J36-E3/5A compare to the SMA5J36AHE3/5A in terms of electrical performance?

The SMA5J36-E3/5A and SMA5J36AHE3/5A are electrically identical: same V_WM (36 V), V_BR (40.0–44.2 V), V_C (58.1 V), P_PPM (500 W), and thermal characteristics. The sole difference is qualification-E3 is commercial grade, HE3 is AEC-Q101 qualified. No electrical parameter deviation exists between the two; the SMA5J36-E3/5A delivers full spec performance without automotive certification overhead.
