Product details
Overview
SAC6.0-E3/54 from Vishay General Semiconductor is a unidirectional low-capacitance TRANSZORB® transient voltage suppressor (TVS) diode in DO-15 package, designed for clamping fast-rising ESD and surge transients on signal lines. It features 6.0 V stand-off voltage (VWM), 7.90 V minimum breakdown voltage (VBR) at 1.0 mA, 11.2 V maximum clamping voltage (VC) at 5.0 A IPP, 500 W peak pulse power (10/1000 μs), and 175 °C max junction temperature - deployed in sensor interface protection for industrial automation systems.
For engineers reviewing the SAC6.0-E3/54 datasheet, SAC6.0-E3/54 pinout, SAC6.0-E3/54 application, or SAC6.0-E3/54 equivalent, key selection criteria include clamping voltage margin vs. IC I/O rail, unidirectional polarity alignment with DC-biased lines, DO-15 thermal derating above 25 °C, and 300 μA max reverse leakage at VWM - critical for low-power sensor nodes and battery-operated edge devices.
Technical Context
This TVS diode operates as a shunt-clamping device triggered by overvoltage events exceeding its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance and low incremental surge resistance, enabling consistent clamping performance across repetitive 10/1000 μs transients at 0.01 % duty cycle.
The SAC6.0-E3/54 is optimized for unidirectional protection of DC-coupled signal paths where reverse polarity is fixed. Its 50 pF junction capacitance (at 0 V) and 3.0 W steady-state power dissipation support high-speed analog and digital interfaces without signal integrity degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse working voltage before clamping begins; sets upper limit for protected line's normal operating range. |
| VBR (min) | 7.90 V at IT = 1.0 mA - Ensures reliable triggering above VWM with margin to avoid false trips during supply ripple or noise. |
| VC (max) | 11.2 V at IPP = 5.0 A - Defines worst-case voltage seen by downstream IC during surge; must stay below IC absolute maximum rating. |
| PPPM | 500 W (10/1000 μs) - Peak energy-handling capability for lightning-induced surges per IEC 61000-4-5 Level 3. |
| ID (max) | 300 μA at VWM - Low leakage preserves battery life and avoids loading of high-impedance sensor outputs. |
| TJ max | +175 °C - Enables operation in under-hood automotive or industrial enclosures without thermal shutdown. |
| Capacitance | 50 pF at 0 V - Minimizes signal distortion on lines up to ~10 MHz; suitable for UART, I²C, and analog sensor inputs. |
Pinout & Package
DO-15 (DO-204AC) molded epoxy package with matte tin-plated leads; cathode indicated by color band; compliant with J-STD-002 solderability and JESD 201 Class 1A whisker testing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Ground-reference terminal | Connected to system ground or low-side return; completes clamping path during positive transients. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A-E3/57 | Same DO-214AC package; 6.0 V VWM, 10.5 V VC at 5.0 A; 600 W PPPM; higher clamping ratio but larger footprint. | Preferred where PCB space allows SMA package and higher surge margin is needed. | Select SMAJ6.0A-E3/57 if layout supports surface-mount and 600 W rating is required for IEC 61000-4-5 Level 4 compliance. |
| P6KE6.8A | DO-15 package; 6.8 V VWM, 11.5 V VC at 5.0 A; 600 W PPPM; wider VWM/VBR spread increases false-trigger risk on noisy 5 V rails. | Better suited for legacy designs using P6KE series; less precise clamping than SAC6.0-E3/54. | Choose P6KE6.8A only for drop-in replacement in existing DO-15 footprints where VWM tolerance ≥6.8 V is acceptable. |
Compared with SMAJ6.0A-E3/57 and P6KE6.8A, the SAC6.0-E3/54 delivers tighter VBR tolerance (7.90 V min), lower clamping voltage (11.2 V), and optimized DO-15 thermal profile for through-hole industrial assemblies - making it ideal for cost-sensitive, high-reliability wired sensor nodes requiring precise 6 V rail protection.

FAQ
What is the maximum clamping voltage of the SAC6.0-E3/54 at 5.0 A peak pulse current?
The SAC6.0-E3/54 has a maximum clamping voltage (VC) of 11.2 V when subjected to a 5.0 A peak pulse current with a 10/1000 μs waveform. This value is measured under standard test conditions (TA = 25 °C) and defines the upper voltage limit imposed on the protected circuit during transient events. Designers must ensure this clamping level remains safely below the absolute maximum ratings of downstream components such as microcontrollers or analog front-ends. The SAC6.0-E3/54 achieves this with low incremental surge resistance and a tightly controlled breakdown characteristic.
Is the SAC6.0-E3/54 suitable for bidirectional signal line protection?
No, the SAC6.0-E3/54 is a unidirectional TVS diode and is not suitable for bidirectional AC or differential signal lines without external configuration. It conducts only when the cathode voltage exceeds the anode by ≥7.90 V, making it appropriate for DC-biased lines like sensor outputs or LIN bus signals referenced to ground. For bidirectional protection, two SAC6.0-E3/54 devices must be connected in series opposition - a configuration explicitly recommended in Vishay's application note for AC line protection. Using a single SAC6.0-E3/54 on a truly bidirectional line risks failure during negative transients.
What is the junction capacitance of the SAC6.0-E3/54 and how does it affect high-speed interfaces?
The SAC6.0-E3/54 exhibits 50 pF of junction capacitance at 0 V bias, a value confirmed in Vishay's electrical characteristics table. This low capacitance minimizes signal loading on data lines, preserving rise/fall times and reducing jitter - critical for interfaces such as I²C (up to 400 kHz), UART (up to 2 Mbps), and analog sensor outputs. At higher frequencies (>10 MHz), designers should verify eye diagram integrity, as even 50 pF can interact with trace impedance. The SAC6.0-E3/54's capacitance is significantly lower than standard TVS diodes (often >100 pF), supporting its use in bandwidth-sensitive applications without requiring additional buffering.
How does the SAC6.0-E3/54 handle thermal derating above 25 °C ambient temperature?
The SAC6.0-E3/54 follows a linear power derating curve starting at 25 °C, with its 3.0 W steady-state power dissipation reduced by 24 mW/°C above that point - reaching zero at +158 °C. This behavior is defined in Figure 2 of the Vishay datasheet (Doc. #88379). In practice, designers must calculate board-level thermal resistance to ensure junction temperature stays within the −55 °C to +175 °C operating range. For example, at 75 °C ambient, the allowable continuous power drops to 1.8 W. The DO-15 package's lead-frame construction provides predictable conduction paths, enabling accurate thermal modeling in industrial PCB layouts.
Does the SAC6.0-E3/54 meet RoHS and lead-free soldering requirements?
Yes, the SAC6.0-E3/54 carries the E3 suffix, indicating full compliance with RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level (MSL) requirements. Its matte tin-plated leads are rated for soldering at 275 °C for up to 10 seconds per JESD 22-B106, supporting both wave and reflow processes. The E3 designation also confirms qualification to JESD 201 Class 1A whisker testing, ensuring long-term reliability in vibration-prone environments such as automotive and industrial control systems. No lead-free exemption or special handling is required for SAC6.0-E3/54 integration.
