Product details
Overview
1.5SMC160CAHM3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, rated for 1500 W peak pulse power (10/1000 μs), 136 V standoff voltage (VWM), and clamping to ≤219 V at 6.8 A peak pulse current. It protects automotive-grade sensor signal lines and MOSFET gate drivers against lightning-induced transients and inductive switching surges.
For engineers reviewing the 1.5SMC160CAHM3_A/H datasheet, 1.5SMC160CAHM3_A/H pinout, 1.5SMC160CAHM3_A/H application, or 1.5SMC160CAHM3_A/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, halogen-free RoHS compliance, and thermal resistance (RθJA = 75 °C/W) under standard PCB pad layout.
Technical Context
This device operates as a voltage-clamped surge protector with symmetrical breakdown behavior in both polarities due to its bidirectional construction. It features glass-passivated junctions for stable leakage performance and low incremental surge resistance to minimize clamping overshoot during fast transients.
Designed for automated SMT assembly, it meets J-STD-020 MSL Level 1 (260 °C peak reflow) and JESD201 Class 2 whisker resistance. Its 150 °C maximum junction temperature and 6.5 W steady-state power dissipation support operation in high-temperature automotive engine-bay environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 136 V - Maximum continuous reverse voltage before conduction begins; defines operating margin below clamping threshold. |
| VBR (Breakdown, min/max) | 152 V / 168 V at 1 mA - Confirmed breakdown range ensures reliable triggering across process variation and temperature. |
| VC (Clamping, at IPPM) | 219 V at 6.8 A (10/1000 μs) - Peak voltage seen by protected circuit during worst-case transient; determines downstream component stress. |
| PPPM | 1500 W - Surge energy handling capacity per single transient event; enables protection against IEC 61000-4-5 Level 4 surges. |
| IPPM | 6.8 A - Peak current delivered during 10/1000 μs waveform; used with VC to compute transient power dissipation. |
| RθJA | 75 °C/W - Thermal resistance from junction to ambient on standard 8 mm × 8 mm copper pads; informs derating above 25 °C ambient. |
| TJ max | +150 °C - Maximum allowable junction temperature; supports under-hood automotive deployment without forced cooling. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, bidirectional configuration with no polarity marking. Dimensions: 7.11 mm × 6.22 mm × 2.62 mm (L × W × H); cathode band absent per bidirectional design.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Terminal 1 | One side of symmetrical PN junction; connects to line being protected (e.g., CAN_H or LIN bus). |
| Anode | Terminal 2 | Second terminal of bidirectional structure; forms common node with Terminal 1 for differential or single-ended clamp. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements including HTOL, TCT, and ESD; supports PPAP documentation. |
| Halogen-free & RoHS-compliant | Meets EU Directive 2011/65/EU and JEDEC JS709C; eliminates brominated flame retardants for safer end-of-life processing. |
| 1500 W peak pulse rating | Withstands 10/1000 μs surges up to 6.8 A without degradation; exceeds IEC 61000-4-5 Level 4 (4 kV, 2 Ω source impedance). |
| Low clamping ratio (VC/VBR ≈ 1.36) | Minimizes overvoltage stress on downstream ICs; enables use with 24 V automotive systems where 36 V-rated components are cost-sensitive. |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard reflow profile (peak 260 °C); eliminates baking requirement prior to assembly. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160CA | Lower peak power (600 W), same VWM (136 V), SMB package (smaller footprint, higher RθJA = 100 °C/W) | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 or automotive load-dump scenarios. | Select when board space is constrained and surge threat level is limited to IEC 61000-4-4 EFT only. |
| 1.5KE160CA | Through-hole TO-204AA (DO-41), identical electrical specs but incompatible with SMT assembly and higher RθJA (120 °C/W) | Requires manual or wave soldering; not viable for high-volume automated production or thermally dense layouts. | Choose only for legacy repair, prototyping, or non-automated low-volume builds where reflow compatibility is not required. |
Compared with SMBJ160CA and 1.5KE160CA, the 1.5SMC160CAHM3_A/H delivers full 1500 W surge immunity in an AEC-Q101-qualified SMT package with superior thermal performance-enabling robust, high-reliability protection in automotive and industrial designs without layout or process compromise.

FAQ
What is the clamping voltage of the 1.5SMC160CAHM3_A/H at its rated peak pulse current?
The 1.5SMC160CAHM3_A/H clamps to a maximum of 219 V when subjected to its specified peak pulse current of 6.8 A under the 10/1000 μs waveform condition. This value is measured per Figure 1 in the Vishay datasheet 88303 and represents the upper limit of voltage seen by protected circuitry during worst-case transient events.
Is the 1.5SMC160CAHM3_A/H suitable for automotive applications?
Yes, the 1.5SMC160CAHM3_A/H is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant, and automotive-grade construction. It is explicitly intended for use in automotive sensor units, ECUs, and infotainment systems where reliability under temperature cycling and vibration is critical.
Does the 1.5SMC160CAHM3_A/H have polarity markings on the package?
No, the 1.5SMC160CAHM3_A/H is a bidirectional TVS diode and carries no polarity marking such as a cathode band. Its symmetrical construction means either terminal may be connected to the line or ground side of the protected circuit without functional impact.
What is the thermal resistance of the 1.5SMC160CAHM3_A/H under standard mounting conditions?
The 1.5SMC160CAHM3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on the recommended 8.0 mm × 8.0 mm copper pad per terminal. This value assumes natural convection and is used to calculate safe operating area derating above 25 °C ambient temperature.
How does the 1.5SMC160CAHM3_A/H differ from unidirectional variants like 1.5SMC160A?
The 1.5SMC160CAHM3_A/H is bidirectional with symmetrical clamping in both directions, while 1.5SMC160A is unidirectional and conducts only in reverse bias. The "CA" suffix denotes bidirectionality, making 1.5SMC160CAHM3_A/H appropriate for AC-coupled or differential signal lines where polarity reversal occurs, unlike DC power rails.
