Product details
Overview
SA5.0-E3/1 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for primary overvoltage protection of sensitive electronics. It features a 5.0 V stand-off voltage (VWM), 6.4–7.07 V breakdown voltage (VBR) at 10 mA, 500 W peak pulse power (10/1000 μs), clamping voltage of 9.2 V at 54.3 A, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SA5.0-E3/1 datasheet, SA5.0-E3/1 pinout, SA5.0-E3/1 application, or SA5.0-E3/1 equivalent, key selection criteria include unidirectional clamping behavior, low VWM/VBR ratio for early turn-on, robust 70 A IFSM surge rating, RoHS-compliant matte tin leads, and compatibility with J-STD-002 solderability standards.
Technical Context
This TVS diode operates as a shunt-type transient protector, leveraging avalanche breakdown to clamp voltage spikes before they reach downstream ICs or MOSFETs. Its glass-passivated junction ensures stable leakage (<600 μA at VWM) and fast response time (<1 ns), critical for protecting signal lines and power rails against ESD, inductive switching transients, and lightning surges.
The device is rated for continuous operation from –55 °C to +175 °C junction temperature, with thermal derating above 25 °C ambient. Its 3.0 W steady-state power dissipation (at TL = 75 °C) and low incremental surge resistance support reliable performance under repetitive surge conditions in automotive and industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum reverse working voltage before conduction; sets upper limit for normal circuit operation without leakage-induced stress. |
| VBR (min/max) | 6.4 V / 7.07 V at 10 mA - Confirmed avalanche onset range; ensures predictable clamping initiation across production lot. |
| IPPM | 54.3 A (10/1000 μs) - Peak surge current it safely diverts; defines minimum PCB trace width and fuse coordination requirements. |
| VC | 9.2 V at IPPM - Clamped voltage seen by protected circuit; must be below absolute maximum ratings of downstream components. |
| IFSM | 70 A (8.3 ms half-sine) - Non-repetitive forward surge capability; supports protection during high-energy inrush or fault events. |
| TJ max. | +175 °C - Enables use in under-hood automotive modules and high-temperature industrial enclosures without thermal shutdown. |
| Leakage (ID) | ≤600 μA at VWM - Low standby current avoids battery drain in always-on systems and signal integrity degradation. |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, molded epoxy case meeting UL 94 V-0 flammability rating. Matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards. Cathode indicated by color band on unidirectional devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point during surge conduction | Connected to protected line (e.g., power rail or signal); must withstand 70 A surge without bond wire failure. |
| Cathode | Avalanche conduction terminal (marked with band) | Connected to ground reference; low-inductance path required to minimize clamping overshoot during fast transients. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated chip junction | Enables stable, low-noise avalanche characteristics and long-term reliability under thermal cycling and humidity exposure. |
| 500 W peak pulse power (10/1000 μs) | Supports protection against ISO 7637-2 Pulse 1/2a/3a and IEC 61000-4-5 Level 3 surges without degradation. |
| AEC-Q101 qualified | Validated for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. |
| Low incremental clamping resistance | Minimizes voltage overshoot during high-di/dt events; critical for safeguarding 3.3 V and 5 V logic-level interfaces. |
| RoHS-compliant E3 suffix | Meets JESD 201 Class 1A whisker resistance; suitable for lead-free reflow and wave soldering processes. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | Same VWM (5.0 V), identical DO-214AC package, but lower PPPM (400 W) and higher VC (9.6 V at 43.4 A). | Less robust for high-energy automotive load dump; better suited for space-constrained consumer PCBs. | Select SMAJ5.0A only if board layout restricts DO-15 footprint and surge energy is limited to ≤400 W. |
| P6SMB5.0A | Same VWM and VBR, DO-214AA package, 600 W PPPM, but higher VC (10.8 V at 55.6 A) and no AEC-Q101 qualification. | Higher clamping voltage risks overstressing 5 V logic; lacks automotive qualification for under-hood use. | Prefer P6SMB5.0A for cost-sensitive industrial controls where AEC-Q101 is not mandated. |
Compared with SMAJ5.0A and P6SMB5.0A, SA5.0-E3/1 delivers superior automotive-grade reliability (AEC-Q101), tighter VC (9.2 V), and optimal balance of surge capacity and clamping precision for 5 V system protection-making it the preferred choice when design assurance and repeatable performance are critical.

FAQ
What is the polarity configuration of SA5.0-E3/1?
SA5.0-E3/1 is a unidirectional TVS diode, meaning it conducts only in reverse bias during overvoltage events. The cathode is marked with a color band on the DO-204AC package. This configuration provides asymmetric clamping ideal for DC power rail protection where forward conduction is not required, unlike bi-directional variants such as SA5.0CA.
Does SA5.0-E3/1 meet automotive qualification standards?
Yes, SA5.0-E3/1 is AEC-Q101 qualified, confirming its suitability for automotive applications including engine control units, body electronics, and infotainment systems. This qualification covers stress tests for temperature cycling, humidity, mechanical shock, and surge endurance-ensuring SA5.0-E3/1 maintains specified VWM, VBR, and clamping performance throughout vehicle lifetime.
What is the maximum clamping voltage of SA5.0-E3/1 under surge conditions?
The maximum clamping voltage (VC) of SA5.0-E3/1 is 9.2 V at a peak pulse current (IPPM) of 54.3 A with a 10/1000 μs waveform. This value is measured per standard test conditions and defines the highest voltage transient that will appear across protected circuitry when SA5.0-E3/1 is activated-critical for ensuring downstream 5 V ICs remain within absolute maximum ratings.
Can SA5.0-E3/1 be used in surface-mount designs?
No, SA5.0-E3/1 uses the axial-leaded DO-204AC (DO-15) package and is intended for through-hole mounting. For surface-mount alternatives with similar electrical specs, consider SMAJ5.0A (DO-214AC) or SMCJ5.0A (DO-214AB), though these differ in power rating, clamping voltage, and qualification status compared to SA5.0-E3/1.
What soldering process is recommended for SA5.0-E3/1?
SA5.0-E3/1 features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, supporting both wave and reflow soldering. Maximum solder dip temperature is 275 °C for 10 seconds per JESD 22-B106. Lead-free reflow profiles must stay within peak temperatures ≤260 °C and time above liquidus ≤60 seconds to avoid package delamination or junction damage.
