Product details
Overview
1.5SMC160CAHM3/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 at 219 V (VC) under 6.8 A peak pulse current - deployed for lightning and inductive-switching surge protection on automotive sensor signal lines and industrial I/O interfaces.
For engineers reviewing the 1.5SMC160CAHM3/H datasheet, 1.5SMC160CAHM3/H pinout, 1.5SMC160CAHM3/H application, or 1.5SMC160CAHM3/H equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), halogen-free RoHS compliance, and real-world clamping behavior for ESD/surge co-design in safety-critical embedded systems.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with breakdown voltage (VBR) specified at 152–168 V (min/max) under 1 mA test current, enabling robust overvoltage clamping during AC transients or reverse-polarity events. Its glass-passivated junction ensures stable leakage (<1 μA at VWM) and fast response (<1 ns), critical for protecting high-speed analog inputs and CAN/LIN bus receivers.
The device is qualified to AEC-Q101, features MSL Level 1 moisture sensitivity, and uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. Thermal performance is defined by RθJL = 15 °C/W (junction-to-leads), supporting reliable operation up to TJ = +150 °C in compact PCB layouts with minimal copper pad area (8.0 mm × 8.0 mm per terminal).
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160CA | Lower PPPM (600 W), same VWM/VC, SMB package (smaller footprint, higher RθJA = 110 °C/W) | Limited to lower-energy surges (IEC 61000-4-5 Level 2); unsuitable for under-hood automotive where ambient exceeds 105 °C | Select when board space is constrained and surge threat level is ≤2 kV; verify thermal margin with reduced copper area. |
| 1.5KE160CA | Through-hole DO-201 package, identical VWM/VC/PPPM, but slower response (>5 ns) and no AEC-Q101 qualification | Not suitable for automated SMT lines or automotive production; requires wave soldering and manual inspection | Choose only for legacy through-hole designs or prototyping where reflow compatibility and automotive qualification are not required. |

FAQ
What is the clamping voltage of the 1.5SMC160CAHM3/H under a 10/1000 μs surge?
The 1.5SMC160CAHM3/H clamps at 219 V when subjected to its rated peak pulse current of 6.8 A with a 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88303 and represents the maximum voltage imposed on the protected circuit during worst-case transient conditions - critical for ensuring downstream ICs remain within their absolute maximum ratings.
Is the 1.5SMC160CAHM3/H qualified for automotive applications?
Yes, the 1.5SMC160CAHM3/H carries the HM3 suffix, indicating it is halogen-free, RoHS-compliant, and AEC-Q101 qualified. It has passed stress tests including temperature cycling, highly accelerated life testing (HALT), and ESD per AEC-Q101 Rev D - making it suitable for use in engine control units, ADAS camera modules, and body electronics where automotive-grade reliability is mandated.
What does the "CA" suffix mean in 1.5SMC160CAHM3/H?
The "CA" suffix in 1.5SMC160CAHM3/H denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression in both polarities, with identical VBR, VWM, and VC characteristics regardless of voltage polarity. This is essential for protecting AC-coupled or differential signal lines such as RS-485, CAN FD, or audio interfaces where polarity reversal may occur.
What is the thermal resistance of the 1.5SMC160CAHM3/H?
The 1.5SMC160CAHM3/H has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 8.0 mm × 8.0 mm copper pads per terminal, and a junction-to-leads resistance (RθJL) of 15 °C/W. These values are specified in the Thermal Characteristics section of Vishay document 88303 and inform thermal design for repetitive surge duty cycles and sustained power dissipation.
How does the 1.5SMC160CAHM3/H differ from unidirectional variants like 1.5SMC160AHM3/H?
The 1.5SMC160CAHM3/H is bidirectional with symmetrical clamping behavior, while 1.5SMC160AHM3/H is unidirectional and features a cathode band marking. The unidirectional version exhibits forward conduction below ~1.2 V and is intended for DC-biased rails; the CA variant avoids forward conduction entirely and protects AC or floating lines - selecting between them depends strictly on circuit polarity architecture and grounding scheme.
