Product details
Overview
1.5SMC180A-E3/57T from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode designed for high-energy surge protection in power and signal lines. It features a 180 V standoff voltage (VWM), 246 V clamping voltage at 6.1 A peak pulse current, and 1500 W peak pulse power capability with a 10/1000 μs waveform - deployed in automotive power supplies, industrial motor controllers, and telecom DC input stages.
For engineers reviewing the 1.5SMC180A-E3/57T datasheet, 1.5SMC180A-E3/57T pinout, 1.5SMC180A-E3/57T application, or 1.5SMC180A-E3/57T equivalent, key selection criteria include unidirectional polarity, SMC (DO-214AB) package compatibility, clamping performance under repetitive transients, and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds its breakdown threshold (171–189 V at 1 mA), it rapidly avalanches to divert surge current away from downstream circuitry. Its glass-passivated junction ensures stable leakage and low capacitance (<50 pF typical at 1 MHz), critical for protecting high-speed analog or power rails without signal distortion.
Thermal design relies on its 75 °C/W junction-to-ambient thermal resistance and 15 °C/W junction-to-lead resistance, requiring minimum 8.0 mm × 8.0 mm copper pads per terminal for rated 1500 W pulse handling. It supports repetitive surges at 0.01% duty cycle and meets J-STD-020 MSL Level 1 with 260 °C reflow peak temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 154 V - maximum continuous reverse operating voltage before conduction begins; defines safe DC/AC operating margin. |
| VBR (Breakdown Voltage) | 171–189 V at 1 mA - precise avalanche initiation range; ensures consistent turn-on across temperature and unit variation. |
| VC (Clamping Voltage) | 246 V at IPPM = 6.1 A - maximum voltage seen by protected circuit during full-rated 10/1000 μs surge; determines stress on downstream components. |
| PPPM (Peak Pulse Power) | 1500 W - energy-handling capacity for standardized lightning/surge transients; validated per IEC 61000-4-5 and ISO 7637-2. |
| ID (Reverse Leakage) | 1.0 μA max at VWM - ultra-low leakage preserves efficiency in high-impedance bias networks and battery-powered systems. |
| TJ max | 150 °C - maximum junction temperature; enables operation in under-hood automotive or enclosed industrial enclosures. |
| Package | SMC (DO-214AB) - industry-standard surface-mount outline with cathode band marking; compatible with automated pick-and-place and reflow. |
Pinout & Package
Package: SMC (DO-214AB), molded plastic case with matte tin-plated leads, UL 94 V-0 rated, MSL Level 1 compliant. Cathode identified by black band on body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; connected to ground or low-side reference in unidirectional TVS configuration. | Provides low-forward-voltage path during positive transients; must be routed to lowest-impedance ground plane. |
| Cathode | Current exit point in reverse bias; connected to protected line (e.g., 24 V rail, CAN bus, sensor supply). | Defines clamping node - all protected circuitry referenced to this terminal; band-marked for orientation verification during assembly. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power (10/1000 μs) | Enables robust protection against IEC 61000-4-5 Level 4 surges (4 kV line-earth) without derating in standard PCB layouts. |
| Glass-passivated junction | Ensures stable VBR over lifetime and temperature; eliminates parameter drift due to moisture or contamination in harsh environments. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (<1 ns response), critical for safeguarding MOSFET gates and microcontroller I/O. |
| AEC-Q101 qualified (HE3/HM3 variants) | Validated for automotive powertrain and chassis applications; includes extended temperature cycling, HTRB, and ESD testing beyond commercial grade. |
| MSL Level 1, 260 °C peak reflow | Supports single-pass lead-free reflow without popcorn cracking or delamination; eliminates pre-bake requirements in high-volume manufacturing. |
Applications
| Automotive Power Supply Protection | Industrial Motor Drive DC Bus |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ180A | Same VWM (154 V) and VC (246 V), but lower PPPM (600 W); SMB package (DO-214AA), smaller footprint and thermal mass. | Limited to lower-energy transients (e.g., IEC 61000-4-2 ESD, not full lightning); unsuitable for ISO 7637-2 load dump. | Select SMBJ180A only when board space is constrained and surge threat level is Class 2 or lower. |
| 1.5KE180A | Through-hole TO-204AE (DO-201AE) package; identical electrical specs (VWM, VBR, VC, PPPM), but higher RθJA (100 °C/W) and no MSL rating. | Requires wave soldering; incompatible with automated SMT lines; not qualified for automotive reflow profiles. | Choose 1.5KE180A only for prototyping or legacy through-hole designs where SMT is unavailable. |
Compared with SMBJ180A and 1.5KE180A, the 1.5SMC180A-E3/57T uniquely combines 1500 W surge capability, SMC surface-mount compatibility, MSL Level 1 reflow support, and AEC-Q101 qualification - making it the only option suitable for volume production of automotive and industrial SMT assemblies requiring full IEC/ISO compliance.

FAQ
What is the clamping voltage of the 1.5SMC180A-E3/57T under full-rated surge conditions?
The 1.5SMC180A-E3/57T clamps to a maximum of 246 V when subjected to its rated 6.1 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88303 and represents the worst-case voltage imposed on protected circuitry during standardized surge events - critical for verifying margin against downstream component absolute maximum ratings.
Is the 1.5SMC180A-E3/57T RoHS-compliant and halogen-free?
Yes, the 1.5SMC180A-E3/57T carries the "E3" suffix, indicating it is RoHS-compliant and manufactured to commercial-grade specifications per Vishay's material categorization (www.vishay.com/doc?99912). It is not halogen-free; for halogen-free compliance, the "M3" variant (e.g., 1.5SMC180A-M3/57T) must be selected.
Does the 1.5SMC180A-E3/57T meet AEC-Q101 requirements?
No - the 1.5SMC180A-E3/57T is commercial-grade. AEC-Q101 qualification applies only to variants with "HE3" or "HM3" suffixes (e.g., 1.5SMC180AHE3_A). The "E3" suffix denotes RoHS compliance and commercial reliability screening, not automotive qualification. For automotive use, specify the HE3 version explicitly.
What is the maximum reverse leakage current for the 1.5SMC180A-E3/57T at its standoff voltage?
The 1.5SMC180A-E3/57T exhibits a maximum reverse leakage current (ID) of 1.0 μA at its rated standoff voltage of 154 V, measured at TA = 25 °C. This ultra-low leakage ensures minimal power loss in always-on circuits and avoids false triggering in high-impedance sensing nodes downstream of the device.
Can the 1.5SMC180A-E3/57T be used in bidirectional configurations?
No - the "A" suffix in 1.5SMC180A-E3/57T designates a unidirectional device. Bidirectional variants use the "CA" suffix (e.g., 1.5SMC180CA). Using a unidirectional TVS in a bidirectional application risks catastrophic failure during negative-going transients, as it conducts freely in forward bias but offers no clamping in reverse polarity.
