Product details
Overview
SAC8.0-E3/54 from Vishay General Semiconductor is a unidirectional low-capacitance TRANSZORB® transient voltage suppressor in DO-15 package, rated for 500 W peak pulse power (10/1000 μs), 8 V stand-off voltage (VWM), and 13.4 V clamping voltage at 5.0 A. It protects MOSFETs and signal lines in industrial sensor interfaces against inductive switching transients.
For engineers reviewing the SAC8.0-E3/54 datasheet, SAC8.0-E3/54 pinout, SAC8.0-E3/54 application, or SAC8.0-E3/54 equivalent, key selection criteria include clamping performance at 5 A, unidirectional polarity, DO-15 mechanical compatibility, and 100 μA max reverse leakage at VWM.
Technical Context
This device operates as a unidirectional avalanche diode with glass-passivated junction, designed to clamp transient overvoltages before they damage downstream ICs or power switches. Its 13.4 V clamping voltage at 5.0 A and 8.89 V minimum breakdown voltage ensure robust protection margin for 5 V rail systems.
It features low incremental surge resistance and fast response time-critical for suppressing sub-microsecond transients from relay coils or motor commutation. The DO-15 package supports manual or automated through-hole assembly and meets UL 94 V-0 flammability rating.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0A | DO-214AA package; 8.0 V VWM, 12.7 V VC @ 5 A; 600 W PPPM | Surface-mount footprint; lower clamping voltage but higher capacitance (~100 pF vs. ~50 pF) | Preferred for space-constrained PCBs where SMT assembly is used and lower clamping is critical |
| P6KE8.2A | DO-15 package; 8.2 V VWM, 13.4 V VC @ 5.0 A; 600 W PPPM; higher leakage (500 μA) | Same through-hole form factor; higher surge rating but less precise VWM tolerance | Used where higher pulse power margin is needed and leakage sensitivity is low |
Compared with SMBJ8.0A and P6KE8.2A, SAC8.0-E3/54 offers tighter VWM tolerance (8.0 V exact), lower leakage (100 μA), and optimized DO-15 mechanical fit for legacy through-hole designs requiring proven field reliability.

FAQ
What is the maximum clamping voltage of SAC8.0-E3/54 at 5.0 A?
The SAC8.0-E3/54 has a maximum clamping voltage (VC) of 13.4 V when subjected to a 10/1000 μs peak pulse current of 5.0 A. This value is measured per the test conditions specified in the Vishay datasheet document 88379 and defines the upper voltage limit imposed on protected circuitry during transient events. Maintaining VC below downstream IC absolute maximum ratings is essential for reliable operation.
Is SAC8.0-E3/54 suitable for bidirectional signal line protection?
No, SAC8.0-E3/54 is a unidirectional transient voltage suppressor and must not be used alone for AC or bidirectional signal lines. For such applications, two SAC8.0-E3/54 devices are required in series opposition (anode-to-anode or cathode-to-cathode), as explicitly shown in the Vishay application schematic for AC line protection. Using a single unidirectional device on AC signals risks forward conduction and failure.
What is the junction temperature rating for SAC8.0-E3/54?
The SAC8.0-E3/54 is rated for an operating junction temperature range of –55 °C to +175 °C. This wide range supports deployment in demanding environments such as industrial motor controls, outdoor telecom enclosures, and under-hood automotive subsystems. Derating of peak pulse power applies above 25 °C ambient, per Figure 2 in the Vishay datasheet 88379.
Does SAC8.0-E3/54 meet RoHS requirements?
Yes, the "E3" suffix in SAC8.0-E3/54 indicates full compliance with RoHS Directive 2011/65/EU and JESD 201 Class 1A whisker testing. The matte tin-plated leads are solderable per J-STD-002 and JESD 22-B102, and the molded epoxy compound meets UL 94 V-0 flammability standards. Full material declarations are available via Vishay's compliance portal.
How does SAC8.0-E3/54 differ from SAC8.5-E3/54?
SAC8.0-E3/54 has a 8.0 V stand-off voltage (VWM) and minimum breakdown voltage of 8.89 V, whereas SAC8.5-E3/54 specifies 8.5 V VWM and 9.44 V VBR(min). Both share identical DO-15 packaging, 500 W PPPM, and 13.4 V / 14.0 V clamping voltages respectively at 5.0 A. Selection depends on required margin between system operating voltage and VWM-SAC8.0-E3/54 suits tighter 5 V rail tolerances.
