Product details
Overview
1.5SMC11AHM3/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 11 V breakdown voltage (VBR), 9.4 V stand-off voltage (VWM), 1500 W peak pulse power rating (10/1000 μs), 96.2 A maximum peak pulse current (IPPM), and clamps to 15.6 V at rated surge. It is used in automotive sensor interfaces, industrial I/O protection, and DC power rail surge suppression.
For engineers reviewing the 1.5SMC11AHM3/H datasheet, 1.5SMC11AHM3/H pinout, 1.5SMC11AHM3/H application, or 1.5SMC11AHM3/H equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, SMC (DO-214AB) package details, thermal resistance data, and real-world design context for transient protection layout and reliability validation.
Technical Context
This TVS diode operates as a unidirectional clamping device with a glass-passivated junction and low incremental surge resistance, enabling fast response (<1 ns) to ESD and lightning-induced transients. Its 1500 W peak pulse power capability is specified under standardized 10/1000 μs waveform conditions with 0.01% duty cycle.
The device is rated for -65 °C to +150 °C operating junction temperature, exhibits 0.075 %/°C temperature coefficient of VBR, and meets J-STD-020 MSL Level 1 with 260 °C reflow peak. The HM3 suffix confirms halogen-free, RoHS-compliant, and AEC-Q101 qualified construction for automotive-grade reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 10.5 V / 11.6 V at 1 mA test current - defines precise clamping onset threshold for circuit-level overvoltage detection |
| VWM | 9.4 V - maximum continuous reverse working voltage before leakage exceeds 5 μA; sets safe DC bias margin |
| IPPM | 96.2 A - peak surge current it safely shunts during 10/1000 μs transient without failure |
| VC | 15.6 V - clamped voltage across device at IPPM; determines protected IC's maximum stress level |
| PPPM | 1500 W - peak pulse power dissipation capability under standardized surge waveform |
| TJ max | +150 °C - maximum junction temperature; enables operation in under-hood automotive environments |
| RθJA | 75 °C/W - thermal resistance from junction to ambient on standard 8 mm × 8 mm copper pads; informs board-level thermal design |

Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting analog output lines of pressure/temperature sensors in engine bay environments exposed to ISO 7637-2 transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between sensor signal line and chassis ground to clamp induced surges before reaching ADC input. Use Value: Maintains signal integrity by limiting transient voltage to ≤15.6 V, preventing ADC saturation or latch-up in microcontroller-based sensor nodes. |
Use Scenario: Safeguarding 24 V digital input channels on programmable logic controller (PLC) modules against field-wiring faults and inductive kickback. IC Role / Device Role / Timing Role: Standoff-rated TVS connected across input terminals to absorb repetitive 1500 W surges without derating. Use Value: Enables reliable operation over 100,000+ surge events while maintaining <5 μA leakage at 9.4 V, preserving input logic thresholds. |
| DC Power Rail Surge Suppression | Automotive Body Control Module (BCM) |
Use Scenario: Secondary protection on 12 V supply rails feeding infotainment head units, following primary fuse and choke filtering. IC Role / Device Role / Timing Role: Fast-clamping TVS absorbing residual transients that pass through front-end filters during load dump events. Use Value: Clamps 96.2 A surge within nanoseconds, limiting rail overshoot to 15.6 V and preventing brownout or reset in sensitive SoCs. |
Use Scenario: Protecting LIN bus transceivers and window motor drivers in BCMs subjected to battery reversal and jump-start conditions. IC Role / Device Role / Timing Role: Unidirectional TVS on VCC pins of LIN ICs, referenced to ground, with cathode tied to supply rail. Use Value: AEC-Q101 qualification ensures long-term reliability under thermal cycling (-40 °C to +125 °C) and vibration, meeting OEM lifetime requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ11A | Lower peak pulse power (600 W), same VBR range, SMB (DO-214AA) package (smaller footprint, higher RθJA) | Not suitable for ISO 7637-2 Pulse 5a; limited to lower-energy transients like ESD or capacitive coupling | Select when board space is constrained and surge energy is ≤600 W; verify thermal margin with RθJA = 100 °C/W |
| 1.5KE11A | Through-hole TO-204AE (DO-41) package, identical electrical specs but no AEC-Q101 qualification or MSL Level 1 rating | Excludes automotive under-hood use; restricted to industrial or consumer PCBs with wave-solder assembly | Choose only for non-automotive designs where automated SMT placement is not required and reflow compatibility is irrelevant |
Compared with SMBJ11A and 1.5KE11A, the 1.5SMC11AHM3/H uniquely combines 1500 W surge handling, AEC-Q101 qualification, MSL Level 1 reflow compatibility, and halogen-free compliance-making it the sole option for production automotive electronics requiring full ISO/IEC 61000-4-5 and AEC reliability validation.

FAQ
What is the clamping voltage of the 1.5SMC11AHM3/H at its rated peak pulse current?
The 1.5SMC11AHM3/H clamps to a maximum of 15.6 V at its rated peak pulse current (IPPM) of 96.2 A under the standardized 10/1000 μs waveform. This value is measured per JEDEC standards and guarantees the protected circuit sees no more than 15.6 V during worst-case surge events, ensuring compatibility with 12 V system ICs rated for ≤16 V absolute maximum.
Is the 1.5SMC11AHM3/H qualified for automotive applications?
Yes, the 1.5SMC11AHM3/H carries the HM3 suffix, confirming it is halogen-free, RoHS-compliant, and AEC-Q101 qualified. This certification validates its reliability for automotive use cases including engine control units, body control modules, and ADAS sensor interfaces under temperature cycling, humidity, and mechanical shock per AEC test protocols.
What does the "H" in the 1.5SMC11AHM3/H ordering code indicate?
The "H" in 1.5SMC11AHM3/H denotes the packaging format: 7-inch diameter plastic tape and reel, with 850 units per reel. This format supports high-speed automated pick-and-place assembly and is compatible with standard SMT feeders used in automotive and industrial manufacturing lines.
How does the 1.5SMC11AHM3/H differ from the 1.5SMC11A-E3/57T variant?
The 1.5SMC11AHM3/H uses halogen-free molding compound and is AEC-Q101 qualified, whereas the 1.5SMC11A-E3/57T is RoHS-compliant but commercial-grade only (no automotive qualification). Both share identical electrical specs and SMC package, but only the HM3/H variant meets OEM requirements for under-hood deployment and long-term reliability validation.
What is the maximum reverse leakage current of the 1.5SMC11AHM3/H at its stand-off voltage?
At its 9.4 V stand-off voltage (VWM), the 1.5SMC11AHM3/H exhibits a maximum reverse leakage current (ID) of 5.0 μA at 25 °C. This low leakage preserves signal integrity in high-impedance sensor interfaces and prevents unnecessary power drain in always-on automotive modules.
