Product details
Overview
1.5SMC160AHE3_A/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. 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, and 1500 W peak pulse power capability with a 10/1000 μs waveform - deployed in automotive sensor interfaces, industrial motor drives, and telecom line protection.
For engineers reviewing the 1.5SMC160AHE3_A/I datasheet, 1.5SMC160AHE3_A/I pinout, 1.5SMC160AHE3_A/I application, or 1.5SMC160AHE3_A/I equivalent, key selection criteria include clamping performance under 10/1000 μs surges, AEC-Q101 qualification status, SMC (DO-214AB) package thermal resistance, and unidirectional polarity marking for correct PCB orientation.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR (179–189 V), it avalanches to divert surge current away from downstream circuitry. Its glass-passivated junction ensures stable leakage (<1 μA at 136 V) and fast response (<1 ns), critical for protecting MOSFET gates and microcontroller I/O pins.
Thermally, it uses an SMC package with RθJA = 75 °C/W and RθJL = 15 °C/W, enabling reliable operation up to TJ = 150 °C. The AEC-Q101 qualification (indicated by HE3 suffix) confirms suitability for automotive environments including engine control units and ADAS sensor modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 136 V - Maximum continuous reverse operating voltage before conduction begins; defines safe operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 179–189 V at 1 mA - Voltage at which avalanche conduction initiates; ensures precise triggering during transients. |
| VC (Clamping Voltage) | 219 V at IPPM = 6.8 A - Maximum voltage seen by protected circuit during 10/1000 μs surge; determines stress on downstream components. |
| PPPM (Peak Pulse Power) | 1500 W - Surge energy handling capacity per single 10/1000 μs event; supports lightning and inductive switching immunity. |
| ID (Reverse Leakage) | <1 μA at VWM - Minimal standby power loss and signal integrity impact in high-impedance circuits. |
| TJ max. | 150 °C - Maximum junction temperature; enables use in under-hood automotive and industrial ambient conditions. |
| AEC-Q101 Qualified | Yes - Validated for automotive reliability including temperature cycling, HTRB, and ESD; required for ECUs and body electronics. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002. Cathode indicated by band; anode is unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Surge current sink node | Connected to protected line; conducts avalanche current to ground during overvoltage events. |
| Anode (unbanded end) | Reference / return path | Typically tied to system ground or low-impedance return; completes clamping current path. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power (10/1000 μs) | Enables protection against IEC 61000-4-5 Level 4 surges (4 kV line-to-ground) without derating in standard layouts. |
| Glass passivated junction | Ensures long-term stability of VBR and leakage across temperature and humidity; eliminates risk of junction corrosion. |
| MSL Level 1 (260 °C reflow) | Supports lead-free assembly without popcorn cracking or delamination; no pre-baking required. |
| AEC-Q101 qualified (HE3 suffix) | Validated for automotive under-hood applications including temperature cycling (-40 °C to +125 °C) and mechanical shock. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ISO 7637-2 pulse 1/2a), improving protection fidelity. |
Applications
| Automotive Sensor Protection | Industrial Motor Drive Inputs |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from load dump and alternator ripple. IC Role / Device Role: Unidirectional shunt clamp placed between signal line and chassis ground. Use Value: Limits transient voltage to ≤219 V during 12 V system load dump (ISO 16750-2), preventing damage to 3.3 V/5 V interface ICs. |

IC Role / Device Role: Primary overvoltage clamp on input terminal block before optocoupler or Schmitt trigger. Use Value: Clamps 1 kV/500 A surges (IEC 61000-4-4) within 1 ns, maintaining signal integrity and eliminating false triggering. |
| Telecom Line Interface | Power Supply Input Stage |
Use Scenario: Shielding Ethernet PHYs and PoE injectors from induced lightning surges on outdoor cabling (EN 61000-4-5). IC Role / Device Role: First-stage protection device on RJ45 line side, upstream of common-mode chokes. Use Value: Withstands 6 kV line-to-ground surges while holding clamping voltage below 220 V, preserving PHY ESD tolerance. |
Use Scenario: Secondary surge suppression on 12–48 V DC input rails of embedded controllers after primary MOV stage. IC Role / Device Role: Precision clamping element that activates only above VWM, avoiding leakage-induced efficiency loss. Use Value: Adds <1 μA leakage at 136 V, enabling >95% efficiency in always-on systems while blocking residual 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 |
|---|---|---|---|
| SMAJ160A-E3/57T | Same VWM (136 V) and VC (219 V), but lower PPPM (400 W); SOD-123FL package (smaller, higher RθJA). | Limited to low-energy surges (IEC 61000-4-2 ESD only); unsuitable for IEC 61000-4-5 or load dump. | Select only for space-constrained consumer-grade designs where 1500 W rating is unnecessary. |
| 1.5KE160A | Through-hole DO-201 package; identical electrical specs but higher thermal resistance (RθJA ≈ 100 °C/W) and no AEC-Q101 qualification. | Not suitable for automated SMT production or automotive under-hood use; requires wave soldering. | Choose only for legacy through-hole boards or non-automotive industrial prototypes requiring manual assembly. |
Compared with SMAJ160A-E3/57T and 1.5KE160A, the 1.5SMC160AHE3_A/I delivers full 1500 W surge immunity in an AEC-Q101-qualified SMT package - making it the only option among the three validated for automotive powertrain and ADAS signal protection.

FAQ
What is the clamping voltage of the 1.5SMC160AHE3_A/I under a 10/1000 μs surge?
The 1.5SMC160AHE3_A/I has a maximum clamping voltage (VC) of 219 V at a peak pulse current (IPPM) of 6.8 A with 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 standardized surge events.
Is the 1.5SMC160AHE3_A/I AEC-Q101 qualified?
Yes, the 1.5SMC160AHE3_A/I is AEC-Q101 qualified, as confirmed by the "HE3" suffix in its ordering code and documented in Vishay's 1.5SMC Series datasheet revision 09-Mar-2026. This qualification covers temperature cycling, high-temperature reverse bias, and mechanical shock testing required for automotive under-hood applications.
What does the "_A/I" suffix mean in 1.5SMC160AHE3_A/I?
The "_A/I" suffix in 1.5SMC160AHE3_A/I indicates the packaging configuration: "A" denotes AEC-Q101 qualification level for the 1.5SMC6.8A to 1.5SMC220A range, and "I" specifies 3500-unit quantity on 13-inch plastic tape and reel - per Vishay's Ordering Information table in document 88303.
Can the 1.5SMC160AHE3_A/I be used in bidirectional configurations?
No, the 1.5SMC160AHE3_A/I is a unidirectional TVS diode, as indicated by the "A" (not "CA") suffix and cathode band marking. For bidirectional operation, Vishay offers the 1.5SMC160CA variant, which provides symmetrical clamping in both polarities and no polarity marking.
What is the thermal resistance of the 1.5SMC160AHE3_A/I?
The 1.5SMC160AHE3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-leads resistance (RθJL) of 15 °C/W, measured on the recommended 0.31" × 0.31" copper pad layout. These values are critical for calculating safe power dissipation in thermally constrained PCB designs.
