Product details

Overview

SA36C-E3/54 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for clamping voltage transients on signal or power lines. It features a 36 V stand-off voltage (V_WM), 40.0–44.2 V breakdown voltage (V_BR) at 1.0 mA, 58.1 V maximum clamping voltage (V_C) at 8.6 A peak pulse current, and 500 W peak pulse power rating with 10/1000 µs waveform - used in automotive sensor interface protection and industrial I/O line surge suppression.

For engineers reviewing the SA36C-E3/54 datasheet, SA36C-E3/54 pinout, SA36C-E3/54 application, or SA36C-E3/54 equivalent, key selection criteria include bi-directional clamping capability, AEC-Q101 qualification, DO-15 mechanical compatibility, and verified 175 °C junction temperature rating for under-hood automotive environments.

Technical Context

The SA36C-E3/54 operates as a bi-directional avalanche diode, leveraging glass-passivated junction technology to deliver symmetrical clamping in both polarities. Its electrical characteristics - including V_WM = 36 V, V_BR = 40.0–44.2 V, and V_C = 58.1 V at I_PPM = 8.6 A - are specified per ANSI/IEEE C62.35 and validated under 10/1000 µs surge conditions.

It meets AEC-Q101 stress test requirements for automotive applications and exhibits low incremental surge resistance with fast response time (<1 ns), enabling effective suppression of ESD, lightning-induced surges, and inductive switching transients on bidirectional data or supply rails without polarity constraints.

Key Specifications

Parameter	Value and Actual Design Meaning
V_WM	36 V - maximum continuous reverse working voltage before clamping begins; defines safe operating margin for 24 V nominal systems.
V_BR (min/max)	40.0 V / 44.2 V at I_T = 1.0 mA - guaranteed avalanche onset range; ensures predictable turn-on across temperature and unit variation.
V_C @ I_PPM	58.1 V at 8.6 A - clamped voltage during 10/1000 µs transient; limits downstream IC stress to sub-60 V during 500 W surge events.
P_PPM	500 W - peak pulse power handling with 0.01 % duty cycle; supports repetitive surge immunity in industrial control interfaces.
T_J max.	175 °C - maximum junction temperature; enables placement near heat sources in engine control units and motor drives.
Package	DO-204AC (DO-15) - industry-standard axial leaded package with UL 94 V-0 molded epoxy; compatible with legacy through-hole assembly and automated taping.
AEC-Q101	Qualified - validated for automotive-grade reliability including HTSL, TCT, and HTRB testing; suitable for non-safety-critical vehicle subsystems.

Pinout & Package

SA36C-E3/54 is a two-terminal bi-directional TVS diode in DO-204AC (DO-15) package; no polarity marking is applied, and both leads serve as symmetrical surge conduction paths. The device uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards.

Pin/Terminal	Circuit Role	Design Meaning
Anode/Cathode (bidirectional)	Surge conduction path	Either terminal conducts avalanche current during overvoltage in either polarity; no cathode band marking required.
Leads (both)	PCB interconnect and thermal path	Matte tin plating ensures reliable solder joint formation; 0.375" (9.5 mm) lead length supports standard lead-forming and heatsinking.

Key Features

Feature	Design Value
Glass passivated chip junction	Enables stable, repeatable avalanche behavior and long-term reliability under repeated surge stress without parameter drift.
500 W peak pulse power (10/1000 µs)	Provides robust protection against ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 Level 3 surges in 24 V vehicle networks.
Bi-directional configuration	Eliminates need for polarity-aware layout; protects AC-coupled lines, differential buses (e.g., RS-485), and floating sensors without external diode pairing.
AEC-Q101 qualification	Confirms suitability for automotive environments including under-hood ECUs, body control modules, and ADAS sensor interfaces.
UL 94 V-0 molding compound	Ensures flame-retardant enclosure integrity during fault conditions, meeting automotive and industrial safety compliance requirements.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SMBJ36CA	Same V_WM (36 V) and bi-directional configuration, but SMB package (surface-mount); lower I_PPM (12.3 A) and higher V_C (58.1 V same, but derated at higher currents).	Requires PCB redesign for SMT placement; better suited for space-constrained designs where reflow compatibility is prioritized over through-hole serviceability.	Select SMBJ36CA when board real estate is limited and automated assembly is mandatory; verify thermal relief pad design for 3.0 W steady-state dissipation.
1.5KE36CA	Higher P_PPM (1500 W), larger DO-201 package; identical V_WM/V_BR specs but slower response due to higher junction capacitance (~150 pF vs. ~50 pF for SA36C).	Better for high-energy utility-grade surges; less suitable for high-speed data lines due to increased capacitive loading and longer recovery time.	Choose 1.5KE36CA for primary AC mains or DC bus protection where energy absorption dominates over signal integrity.

Compared with SMBJ36CA and 1.5KE36CA, SA36C-E3/54 delivers optimal balance of automotive qualification, through-hole manufacturability, and low-capacitance clamping - making it preferred for cost-sensitive, medium-energy automotive and industrial I/O protection where DO-15 footprint and AEC-Q101 compliance are mandatory.

FAQ

What is the polarity configuration of SA36C-E3/54?

The SA36C-E3/54 is a bi-directional Transient Voltage Suppressor, meaning it provides symmetrical clamping in both forward and reverse directions. Unlike uni-directional variants (e.g., SA36A-E3/54), it has no cathode marking and functions identically regardless of terminal orientation - ideal for protecting AC-coupled or floating signal paths where polarity cannot be guaranteed.

Does SA36C-E3/54 meet automotive reliability standards?

Yes, SA36C-E3/54 is AEC-Q101 qualified, having passed stress tests including high-temperature operating life (HTOL), temperature cycling (TCT), and highly accelerated stress testing (HAST). This qualification confirms its suitability for non-safety-critical automotive applications such as body electronics, infotainment interfaces, and sensor signal conditioning circuits.

What is the maximum clamping voltage of SA36C-E3/54 under surge conditions?

The SA36C-E3/54 has a maximum clamping voltage (V_C) of 58.1 V at 8.6 A peak pulse current (I_PPM) with a 10/1000 µs waveform. This value is measured per standardized test conditions and represents the upper bound of voltage seen by protected circuitry during a 500 W transient event - critical for ensuring downstream ICs remain within their absolute maximum voltage ratings.

Can SA36C-E3/54 be used in place of a uni-directional TVS like SA36A-E3/54?

No - SA36C-E3/54 is not a direct replacement for SA36A-E3/54 due to fundamental polarity differences. While both share identical V_WM, V_BR, and V_C values, the uni-directional SA36A-E3/54 requires correct cathode orientation and blocks reverse current, whereas SA36C-E3/54 conducts in both directions. Substitution requires schematic and layout review to confirm bi-directional operation is acceptable in the target circuit.

What is the package type and lead finish of SA36C-E3/54?

SA36C-E3/54 uses the DO-204AC (DO-15) axial-leaded package with matte tin-plated leads. The finish complies with J-STD-002 and JESD 22-B102 for solderability, and the E3 suffix indicates compliance with JESD 201 Class 1A whisker testing - ensuring long-term reliability in high-vibration or thermally cycled environments.
