Product details
Overview
SMA5J36CHE3/5A from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, designed for high-energy surge protection on signal and power lines. It features a 36 V stand-off voltage (VWM), 40.0–44.2 V breakdown voltage (VBR), 500 W peak pulse power (PPPM), and clamps transients to ≤58.1 V at 8.6 A IPPM - used in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMA5J36CHE3/5A datasheet, SMA5J36CHE3/5A pinout, SMA5J36CHE3/5A application, or SMA5J36CHE3/5A equivalent, key selection criteria include bi-directional clamping capability, AEC-Q101 qualification, 150 °C junction rating, low incremental surge resistance, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates symmetrically in both directions, enabling protection of AC-coupled or floating signal paths without polarity concerns. Its glass-passivated junction ensures stable VBR tolerance and long-term reliability under repetitive surge stress.
Designed for 10/1000 μs waveform compliance, it delivers 500 W peak pulse power dissipation with thermal resistance RθJA = 80 °C/W and RθJL = 25 °C/W - supporting robust thermal performance when mounted per recommended pad layout.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J36CA-E3/5A | Same VWM/VBR/PPPM specs; identical DO-214AC package; HE3 suffix denotes AEC-Q101 qualification, E3 is commercial grade | No functional difference in circuit protection; differs only in qualification scope and whisker test class (HE3 = JESD 201 Class 2) | Select SMA5J36CHE3/5A for automotive OEM programs requiring full AEC-Q101 traceability and Class 2 whisker resistance |
| SMCJ36CA | Higher PPPM (1500 W), larger DO-214AB (SMC) package, same VWM/VBR range, also AEC-Q101 qualified | Used where higher surge energy handling is needed; requires PCB area increase and layout revision | Choose SMCJ36CA only if system-level testing shows 500 W insufficient - not a drop-in replacement due to footprint mismatch |
Compared with SMA5J36CA-E3/5A, the SMA5J36CHE3/5A provides identical electrical protection with enhanced reliability validation; versus SMCJ36CA, it trades surge capacity for compactness and direct compatibility with space-constrained SMA layouts.

FAQ
What is the polarity configuration of SMA5J36CHE3/5A?
The SMA5J36CHE3/5A is a bi-directional TVS diode with no polarity marking - its terminals are functionally identical in both directions. This eliminates orientation concerns during placement and enables protection of AC-coupled or floating signal paths. The device meets all electrical characteristics symmetrically, as confirmed in the Vishay datasheet Document Number 88875.
Does SMA5J36CHE3/5A meet automotive qualification standards?
Yes, SMA5J36CHE3/5A is AEC-Q101 qualified, as indicated by the "HE3" suffix. This certification validates its reliability for automotive applications including under-hood environments, with testing covering temperature cycling, humidity bias, mechanical shock, and surge endurance. The qualification applies specifically to the SMA5J36CHE3/5A variant, not just the family.
What is the maximum clamping voltage for SMA5J36CHE3/5A at rated surge current?
The maximum clamping voltage (VC) for SMA5J36CHE3/5A is 58.1 V at 8.6 A peak pulse current (IPPM), measured under the standard 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuits during surge events and is guaranteed across the full operating temperature range per the Vishay datasheet.
Is SMA5J36CHE3/5A RoHS compliant and lead-free?
Yes, SMA5J36CHE3/5A is RoHS compliant and lead-free, as confirmed by the "E3" and "HE3" suffixes per Vishay's material categorization policy (Document Number 99912). The matte tin-plated leads meet J-STD-002 and JESD 22-B102 solderability standards, and the molding compound complies with UL 94 V-0 flammability requirements.
What is the thermal resistance specification for SMA5J36CHE3/5A?
SMA5J36CHE3/5A has a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W and junction-to-lead resistance (RθJL) of 25 °C/W, measured under standard conditions (TA = 25 °C, mounted on 0.2" × 0.2" copper pads). These values inform thermal design margins when deploying the device in high-power or high-temperature environments.
