Product details
Overview
1.5SMC160CAHM3/I from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It delivers 1500 W peak pulse power (10/1000 μs), clamps at 219 V under 6.8 A peak pulse current, and features a 136 V standoff voltage with ≤1 μA leakage at 25 °C - deployed in automotive sensor interfaces, industrial I/O modules, and telecom line protection.
For engineers reviewing the 1.5SMC160CAHM3/I datasheet, 1.5SMC160CAHM3/I pinout, 1.5SMC160CAHM3/I application, or 1.5SMC160CAHM3/I equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, SMC (DO-214AB) package compatibility, and thermal resistance of 75 °C/W for board-level surge resilience.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, enabling protection against voltage transients from either direction without polarity sensitivity. Its glass-passivated junction ensures stable breakdown behavior and low incremental surge resistance, critical for fast response to ESD and lightning-induced surges.
The device is rated for 150 °C maximum junction temperature and meets J-STD-020 MSL Level 1, supporting lead-free reflow up to 260 °C. Its halogen-free, RoHS-compliant construction (HM3 suffix) and AEC-Q101 qualification confirm suitability for automotive-grade production environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 μs) | 1500 W - sustains high-energy transients without failure in automotive load-dump or lightning surge events |
| Standoff Voltage (VWM) | 136 V - defines maximum continuous operating voltage before clamping initiates |
| Clamping Voltage (VC @ IPPM) | 219 V @ 6.8 A - limits downstream voltage stress during surge, protecting 200 V-rated components |
| Breakdown Voltage (VBR min/max) | 152 V / 168 V @ 1 mA - ensures predictable, repeatable avalanche onset within tight tolerance |
| Leakage Current (ID @ VWM) | ≤1 μA @ 25 °C - negligible standby power loss and no signal integrity impact in high-impedance circuits |
| Junction Temperature Range | –65 °C to +150 °C - supports operation in under-hood automotive and industrial ambient conditions |
| Thermal Resistance (RθJA) | 75 °C/W - enables thermal design on standard PCB copper pads (8.0 mm × 8.0 mm per terminal) |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, bidirectional - no polarity marking; symmetrical two-terminal configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| MSL Level 1 moisture sensitivity | Enables direct placement without baking; compatible with standard SMT reflow profiles up to 260 °C |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/FlexRay transceiver inputs and analog sensor feeds (e.g., pressure, temperature) from load dump and ESD in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional clamping element placed directly at connector entry point to shunt surge energy before reaching signal conditioning ICs. Use Value: Prevents latch-up or permanent damage to 3.3 V/5 V interface ICs by limiting transient voltage to ≤219 V while maintaining <1 μA leakage at 136 V nominal bus voltage. |
Use Scenario: Safeguarding 24 V DC digital input modules in programmable logic controllers against field-wiring induced surges and inductive kickback. IC Role / Device Role / Timing Role: Primary overvoltage clamp on each isolated input channel, mounted adjacent to terminal block entry. Use Value: Enables reliable operation under IEC 61000-4-4 (EFT) and IEC 61000-4-5 (surge) immunity testing up to 2 kV/1 kA due to 1500 W pulse handling and low Rdyn. |
| Telecom Line Interface Protection | Power Supply Input Stage Clamping |
Use Scenario: Shielding RS-485/RS-232 transceivers and Ethernet PHYs in base station backhaul equipment from lightning-induced common-mode surges. IC Role / Device Role / Timing Role: Differential- or common-mode TVS pair installed at board edge before isolation transformers or signal conditioners. Use Value: Symmetric clamping ensures equal protection for both signal polarities, preserving signal integrity while meeting Telcordia GR-1089-CORE Level 3 surge requirements. |
Use Scenario: Secondary clamping stage after primary MOV or fuse, protecting DC-DC converter inputs in 48 V telecom rectifiers and industrial SMPS units. IC Role / Device Role / Timing Role: Fast-response backup suppressor that activates after slower primary protection, limiting residual voltage spikes to safe levels. Use Value: Reduces risk of MOSFET gate oxide rupture or controller IC latch-up by clamping 48 V rail transients to ≤219 V with sub-nanosecond response. |
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 peak power (600 W), same 136 V VWM and bidirectional SOD-123FL package | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5a or IEC 61000-4-5 Level 4 | Select when space-constrained layouts require smaller SMB package and surge energy is ≤600 W |
| 1.5KE160CA | Higher leakage (5 μA), axial-leaded DO-201AD package, non-AEC-Q101 | Not suitable for automated SMT assembly or automotive under-hood use; requires through-hole mounting | Choose only for legacy through-hole designs where rework flexibility outweighs AEC-Q101 and SMT requirements |
Compared with SMBJ160CA and 1.5KE160CA, the 1.5SMC160CAHM3/I provides 2.5× higher pulse power in an AEC-Q101-qualified SMT package with halogen-free compliance - making it the preferred choice for new automotive and industrial designs requiring robust, automated, and environmentally compliant surge protection.

FAQ
What is the clamping voltage of the 1.5SMC160CAHM3/I under peak pulse conditions?
The 1.5SMC160CAHM3/I clamps at 219 V when subjected to its rated peak pulse current of 6.8 A using the standard 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88303 and reflects the maximum voltage seen across the device during surge events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is the 1.5SMC160CAHM3/I suitable for automotive applications?
Yes, the 1.5SMC160CAHM3/I is AEC-Q101 qualified (indicated by the HM3 suffix) and specifically designed for automotive use, including engine control units, body electronics, and ADAS sensor interfaces. Its halogen-free construction, MSL Level 1 rating, and operation up to +150 °C junction temperature meet stringent automotive reliability and manufacturing requirements.
What does the "CA" suffix mean in 1.5SMC160CAHM3/I?
The "CA" suffix in 1.5SMC160CAHM3/I denotes a bidirectional configuration - meaning the device provides symmetrical transient voltage suppression in both forward and reverse directions. Unlike unidirectional variants (e.g., 1.5SMC160AHM3/I), it has no cathode band marking and functions identically regardless of applied polarity.
What is the standoff voltage (VWM) of the 1.5SMC160CAHM3/I?
The standoff voltage (VWM) of the 1.5SMC160CAHM3/I is 136 V - the maximum DC or RMS voltage the device can withstand continuously without entering avalanche conduction. This parameter ensures minimal leakage (<1 μA at 25 °C) during normal operation while allowing rapid transition into clamping mode during overvoltage events.
How does the 1.5SMC160CAHM3/I differ from the 1.5SMC160AHM3/I?
The 1.5SMC160CAHM3/I is bidirectional (CA), whereas the 1.5SMC160AHM3/I is unidirectional (A). The CA version clamps symmetrically in both directions with no polarity marking; the A version has a cathode band and only clamps in reverse bias. Their VWM, VBR, and VC values differ accordingly - the unidirectional variant has a lower VWM (136 V vs. 136 V is coincidentally same here, but breakdown asymmetry applies).
