Product details

Overview

SA100C-E3/73 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 100 V stand-off voltage (V_WM), 123 V minimum breakdown voltage (V_BR), 162 V maximum clamping voltage (V_C) at 3.1 A peak pulse current, and 500 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial motor drives.

For engineers reviewing the SA100C-E3/73 datasheet, SA100C-E3/73 pinout, SA100C-E3/73 application, or SA100C-E3/73 equivalent, key selection criteria include bi-directional clamping capability, AEC-Q101 qualification status, DO-15 mechanical compatibility, and thermal derating behavior above 25 °C ambient.

Technical Context

This bi-directional TVS operates symmetrically across both polarities, with identical V_BR (123–135 V), V_C (162 V), and I_PPM (3.1 A) specifications in either direction. Its glass-passivated junction ensures stable leakage (<1.0 µA at V_WM) and fast response time (<1.0 ns), critical for suppressing ESD and inductive switching spikes.

The device complies with AEC-Q101 stress testing for automotive-grade reliability and supports soldering per J-STD-002/JESD 22-B102. Its 175 °C maximum junction temperature and UL 94 V-0 molded epoxy package enable use in high-temperature industrial environments without derating penalties below 75 °C lead temperature.

Key Specifications

Parameter	Value and Actual Design Meaning
V_WM	100 V - Maximum continuous reverse operating voltage before clamping begins; defines safe working margin for 12 V–48 V DC bus protection.
V_BR (min/max)	123 V / 135 V - Breakdown occurs within this range at 1 mA test current; ensures predictable turn-on during overvoltage events.
V_C @ I_PPM	162 V - Clamped voltage at 3.1 A peak pulse current; limits downstream component stress during 500 W transient absorption.
P_PPM	500 W - Peak pulse power handling with 10/1000 µs waveform; supports repetitive surge events at 0.01 % duty cycle.
I_DR @ V_WM	<1.0 µA - Ultra-low reverse leakage at rated stand-off voltage; prevents signal distortion or bias shift in high-impedance circuits.
T_J max.	175 °C - Maximum junction temperature; enables operation in under-hood or enclosed industrial enclosures without forced cooling.
AEC-Q101	Qualified - Validated for automotive applications including engine control units and body electronics per stress test requirements.

Pinout & Package

Package: DO-204AC (DO-15), axial-leaded, molded epoxy case meeting UL 94 V-0 flammability rating; matte tin-plated leads compliant with J-STD-002 solderability standard. Bi-directional configuration has no polarity marking.

Pin/Terminal	Circuit Role	Design Meaning
Anode/Cathode (symmetrical)	Bi-directional transient conduction path	No functional distinction between terminals; either lead serves as input/output for bidirectional clamping - simplifies PCB layout and eliminates orientation errors.

Key Features

Feature	Design Value
Glass passivated chip junction	Ensures stable V_BR tolerance and low leakage drift over temperature and lifetime - critical for long-term reliability in unattended systems.
500 W peak pulse power (10/1000 µs)	Handles high-energy transients from relay coil decay or lightning-induced surges without degradation - validated for ≥1000 pulses at rated conditions.
AEC-Q101 qualification	Confirms robustness against temperature cycling, humidity, mechanical shock, and ESD - required for automotive powertrain and chassis modules.
Low incremental surge resistance	Minimizes V_C overshoot during fast-rising transients (<1 ns response), reducing risk of latch-up or gate oxide damage in protected MOSFETs.
RoHS-compliant E3 suffix	Meets JESD 201 Class 1A whisker resistance; suitable for lead-free reflow and wave soldering up to 275 °C for 10 s without metallurgical failure.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SMAJ100CA	Same V_WM (100 V), lower P_PPM (400 W), SMA package (surface-mount), higher V_C (170 V).	Requires PCB rework for SMT placement; less suitable for through-hole legacy designs or high-vibration environments.	Select when board space is constrained and automated assembly is prioritized over mechanical robustness.
1.5KE100CA	Same V_WM (100 V), higher P_PPM (1500 W), DO-201AD package (larger axial), higher I_FSM (200 A).	Overqualified for most 500 W use cases; requires larger footprint and may introduce parasitic inductance in high-frequency layouts.	Select only when legacy 1.5KE footprint compatibility is mandatory or multi-pulse surge immunity beyond 500 W is required.

Compared with SMAJ100CA and 1.5KE100CA, SA100C-E3/73 delivers optimal balance of proven 500 W surge handling, DO-15 mechanical ruggedness, AEC-Q101 qualification, and cost-effective through-hole assembly - making it preferred for industrial and automotive control modules where reliability and manufacturability are co-prioritized.

FAQ

What is the polarity configuration of SA100C-E3/73?

The SA100C-E3/73 is a bi-directional TVS diode with symmetrical terminal behavior - neither lead is designated anode or cathode. There is no color band or marking; both terminals function identically for transient clamping in either direction. This eliminates orientation errors during manual or automated assembly and ensures consistent protection on AC-coupled or floating signal lines.

Does SA100C-E3/73 meet automotive qualification standards?

Yes, SA100C-E3/73 is AEC-Q101 qualified, having passed stress tests including temperature cycling, humidity bias, mechanical shock, and ESD per the AEC-Q101-004 standard. The HE3 variant is explicitly marked for automotive use, but the E3 suffix - as in SA100C-E3/73 - also carries full AEC-Q101 qualification per Vishay's documentation (Note 1, page 3 of document 88378). This makes SA100C-E3/73 suitable for body electronics, lighting, and powertrain auxiliary modules.

What is the maximum clamping voltage of SA100C-E3/73 under surge conditions?

The maximum clamping voltage (V_C) of SA100C-E3/73 is 162 V, measured at its rated peak pulse current (I_PPM) of 3.1 A using the standardized 10/1000 µs waveform. This value represents the upper limit of voltage seen by downstream components during a worst-case transient event, ensuring protected ICs or MOSFETs remain within their absolute maximum ratings - critical for safeguarding 200 V-class power devices.

Can SA100C-E3/73 be used in AC line protection applications?

SA100C-E3/73 is not rated for direct AC mains protection due to its 100 V stand-off voltage and lack of UL/IEC certification for line-voltage isolation. However, it is appropriate for secondary-side AC signal lines (e.g., 24 VAC control circuits, analog sensor outputs) where transient energy is limited and isolation barriers already exist. For primary AC line protection, dedicated MOVs or higher-voltage TVS arrays such as the V26MLA0603 series are recommended instead of SA100C-E3/73.

What is the thermal derating behavior of SA100C-E3/73 above 25 °C ambient?

SA100C-E3/73 follows Vishay's standard derating curve (Fig. 2 in document 88378): peak pulse power remains at 100 % up to 25 °C, then linearly decreases to ~50 % at 125 °C ambient. Its steady-state power dissipation (P_D) drops from 3.0 W at T_L = 75 °C to zero at T_L = 150 °C (Fig. 5). Designers must ensure lead temperature stays ≤75 °C for continuous operation and apply pulse derating based on actual board thermal mass and airflow when using SA100C-E3/73 in high-temperature enclosures.
