Product details
Overview
1.5SMC160CA-E3/9AT from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMC (DO-214AB) package, designed for high-energy surge protection. It features a 160 V standoff voltage (VWM), 179 V minimum breakdown voltage (VBR), 219 V maximum clamping voltage (VC) at 6.8 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM) with 10/1000 μs waveform - deployed to safeguard signal lines and power rails in automotive sensor interfaces and industrial I/O modules.
For engineers reviewing the 1.5SMC160CA-E3/9AT datasheet, 1.5SMC160CA-E3/9AT pinout, 1.5SMC160CA-E3/9AT application, or 1.5SMC160CA-E3/9AT equivalent, key selection criteria include bidirectional clamping symmetry, low clamping ratio (VC/VBR ≈ 1.22), MSL Level 1 moisture sensitivity, RoHS-compliant matte tin terminations, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, delivering identical clamping performance regardless of transient polarity - critical for protecting AC-coupled or differential signal paths. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time (<1.0 ps), while the low incremental surge resistance supports robust energy absorption without thermal runaway.
The device is rated for 150 °C maximum junction temperature and derates linearly above 25 °C ambient per Fig. 2, with thermal resistance RθJA = 75 °C/W (on recommended pad layout) and RθJL = 15 °C/W. It meets UL 497B recognition (QVGQ2) and is AEC-Q101 qualified when ordered with HE3/HM3 suffixes - though 1.5SMC160CA-E3/9AT itself is commercial-grade RoHS-compliant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 160 V - maximum continuous reverse voltage before conduction begins; defines operating margin below clamping threshold |
| VBR (Breakdown min) | 179 V at 1.0 mA - guaranteed turn-on voltage under DC test; ensures predictable activation during transients |
| VC (Clamping max) | 219 V at IPPM = 6.8 A - peak voltage seen by protected circuit during 10/1000 μs surge; determines stress on downstream ICs |
| PPPM | 1500 W - peak pulse power handling with 10/1000 μs waveform; enables protection against lightning-induced surges per IEC 61000-4-5 |
| ID (Leakage) | <1.0 μA at VWM - ultra-low reverse leakage preserves signal integrity and minimizes standby power loss |

| Telecom Line Card Protection | Consumer USB Port ESD Suppression |
Use Scenario: Secondary protection on xDSL or Ethernet PHY lines exposed to lightning-induced common-mode surges in outdoor cabinets. IC Role / Device Role / Timing Role: Coordinated clamp stage following gas discharge tube (GDT) primary protection to handle residual energy and fast-rising edges. Use Value: Absorbs up to 1500 W of residual surge energy after GDT crowbarring, reducing let-through voltage to sub-250 V levels compatible with PHY IC absolute max ratings. |
Use Scenario: Board-level ESD protection for USB 2.0 data lines (D+/D−) in portable media players and docking stations. IC Role / Device Role / Timing Role: Low-capacitance bidirectional TVS placed adjacent to USB connector to divert ±15 kV contact ESD per IEC 61000-4-2. Use Value: Adds only ~15 pF junction capacitance at 0 V bias - preserves signal rise/fall times and eye diagram integrity at 480 Mbps full-speed USB. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160CA | Same VWM (160 V) and bidirectional configuration, but lower PPPM (600 W); SMB package (smaller footprint, higher RθJA = 85 °C/W) | Limited to lower-energy transients (e.g., IEC 61000-4-2 ESD only); unsuitable for IEC 61000-4-5 lightning surges | Select when board space is constrained and surge threat level is limited to ESD or capacitive coupling events |
| 1.5KE160CA | Same electrical specs (VWM, VBR, VC), but through-hole DO-201AE package; higher thermal mass but incompatible with SMT automation | Used in legacy designs or prototyping where manual assembly or socketing is acceptable; lacks MSL Level 1 compliance | Choose only for repair, replacement, or non-automated production - not for new SMT-based designs |
Compared with SMBJ160CA and 1.5KE160CA, the 1.5SMC160CA-E3/9AT uniquely delivers 1500 W surge capability in an MSL Level 1 SMT package, enabling direct integration into high-volume automotive and industrial PCBs without reflow constraints or layout compromise.

FAQ
What is the clamping voltage of the 1.5SMC160CA-E3/9AT at its rated peak pulse current?
The 1.5SMC160CA-E3/9AT has a maximum clamping voltage (VC) of 219 V when subjected to its specified peak pulse current (IPPM) of 6.8 A using a 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet 88303 and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring downstream ICs remain within their absolute maximum ratings.
Is the 1.5SMC160CA-E3/9AT suitable for automotive applications requiring AEC-Q101 qualification?
The 1.5SMC160CA-E3/9AT is RoHS-compliant and commercial-grade but not AEC-Q101 qualified. For automotive use, Vishay offers the 1.5SMC160CAHE3_A variant (with HE3 suffix), which carries full AEC-Q101 qualification. Engineers must select the HE3 or HM3 version if compliance with AEC-Q101 is required - the -E3/9AT suffix alone does not imply automotive qualification.
What is the junction-to-ambient thermal resistance (RθJA) for the 1.5SMC160CA-E3/9AT under standard mounting conditions?
The 1.5SMC160CA-E3/9AT has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on the minimum recommended pad layout: 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. This value assumes still air convection and is used to calculate junction temperature rise under steady-state power dissipation (PD = 6.5 W) or repetitive surge conditions.
Does the 1.5SMC160CA-E3/9AT have polarity markings on its package?
No, the 1.5SMC160CA-E3/9AT does not have polarity markings because it is a bidirectional TVS diode. Unlike unidirectional variants (e.g., 1.5SMC160A), bidirectional types such as the 1.5SMC160CA-E3/9AT feature symmetrical conduction in both directions and carry no cathode band or other orientation indicator - enabling zero-orientation placement in automated SMT processes.
What is the maximum peak pulse current (IPPM) rating for the 1.5SMC160CA-E3/9AT, and how is it defined?
The 1.5SMC160CA-E3/9AT is rated for a maximum peak pulse current (IPPM) of 6.8 A, defined using the standardized 10/1000 μs double-exponential waveform per REA and IEC 61000-4-5. This current corresponds to the 1500 W peak pulse power rating and is measured under non-repetitive, single-pulse conditions with device junction temperature held at 25 °C - derating applies above ambient temperatures per Figure 2 in the datasheet.
