Product details
Overview
TPSMC22AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients on power and signal lines. It features a 22.0 V nominal breakdown voltage (VBR), 18.8 V stand-off voltage (VWM), 1500 W peak pulse power (10/1000 µs), 49.0 A peak pulse current (IPPM), and 30.6 V maximum clamping voltage (VC) - deployed in automotive sensor protection and industrial power supply input stages.
For engineers reviewing the TPSMC22AHE3_A/H datasheet, TPSMC22AHE3_A/H pinout, TPSMC22AHE3_A/H application, or TPSMC22AHE3_A/H equivalent, key selection criteria include its AEC-Q101 qualification, 185 °C junction temperature rating, unidirectional polarity, low clamping ratio (VC/VBR = 1.39), and compatibility with high-reliability automotive PCB layouts requiring MSL Level 1 reflow.
Technical Context
The TPSMC22AHE3_A/H uses passivated anisotropic rectifier technology to achieve stable breakdown characteristics across temperature. Its 185 °C maximum junction temperature and AEC-Q101 qualification confirm suitability for under-hood automotive environments where thermal derating and long-term reliability are critical.
It delivers 1500 W peak pulse power per 10/1000 µs waveform with low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of ESD, load dump, and inductive switching transients on 12 V and 24 V systems without sacrificing forward conduction integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 20.9 / 22.0 / 23.1 V - defines precise voltage threshold at which clamping initiates under 1 mA test current |
| VWM | 18.8 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA |
| VC @ IPPM | 30.6 V - clamped voltage during 49.0 A transient, limiting downstream IC stress to safe levels |
| PPPM | 1500 W - peak transient energy absorption capability using standard 10/1000 µs waveform |
| IFSM | 200 A - surge current handling for 8.3 ms half-sine wave, supporting load-dump immunity |
| TJ max. | 185 °C - enables operation in high-temperature engine control units without thermal shutdown |
| Polarity | Unidirectional - protects against positive transients only; cathode band denotes protected line side |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, matte tin-plated leads, RoHS-compliant and AEC-Q101 qualified (HE3 suffix). Dimensions: 7.11 mm × 6.22 mm × 2.90 mm (L × W × H); mounting pad layout requires 8.0 mm × 8.0 mm copper area per terminal for thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient clamp output node | Connected to protected line (e.g., 12 V rail); conducts when voltage exceeds VWM |
| Anode | Reference/ground return path | Connected to system ground or low-impedance return; completes clamping loop during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| Junction passivation optimized design | Ensures stable VBR drift <±5% over 1000 hrs at 150 °C, critical for automotive lifetime validation |
| MSL Level 1 (260 °C peak) | Enables single-pass lead-free reflow without popcorn effect or delamination risk |
| Low clamping ratio (VC/VBR = 1.39) | Minimizes overvoltage margin required for downstream MOSFET gate drivers and microcontrollers |
| AEC-Q101 qualification | Validated for automotive applications including engine control modules, body electronics, and ADAS sensors |
| 10/1000 µs waveform compliance | Meets ISO 7637-2 Pulse 1, 2a, 3a/b and ISO 16750-2 load-dump immunity requirements |
Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Clamping |
|---|---|
Use Scenario: Protecting 12 V power rails in engine control units from load-dump transients up to 35 V. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between battery feed and DC/DC converter input. Use Value: Limits clamped voltage to 30.6 V, preventing damage to 36 V-rated input stages while surviving 200 A surge currents. |
Use Scenario: Shielding analog outputs of pressure sensors in factory automation PLCs from ESD and cable discharge events. IC Role / Device Role / Timing Role: Low-capacitance TVS on 0–5 V signal lines interfacing with microcontroller ADC inputs. Use Value: Sub-1 ns response ensures transients are suppressed before reaching sensitive analog front-end circuitry. |
| Telecom DC Power Feeds | Consumer Device USB Port Protection |
Use Scenario: Safeguarding PoE-powered network switches against induced surges on 48 V DC input lines. IC Role / Device Role / Timing Role: Primary clamping device upstream of hot-swap controllers and PMICs. Use Value: 1500 W peak power rating handles multi-pulse surge events common in outdoor telecom cabinets. |
Use Scenario: Adding secondary-level overvoltage protection on USB VBUS lines in smart home hubs. IC Role / Device Role / Timing Role: Standoff-rated TVS placed after primary fuse and upstream of USB controller IC. Use Value: 18.8 V VWM avoids false triggering during 5.25 V USB spec tolerance while clamping >12 V faults. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ22A | Lower PPPM (400 W), same VBR (22.0 V), SMA package (smaller thermal mass) | Limited to lower-energy transients; not rated for automotive load-dump or AEC-Q101 | Select when cost-sensitive consumer designs require basic ESD protection without automotive qualification. |
| SMCJ22A | Same SMC package, 1500 W rating, but VBR min = 20.9 V (identical), no AEC-Q101 qualification in base version | Requires separate AEC-Q101 variant (e.g., SMCJ22AHM3); HE3 suffix not standardized across manufacturers | Choose if sourcing flexibility is prioritized and AEC-Q101 is verified per lot; verify HE3 suffix mapping per distributor. |
Compared with SMAJ22A and SMCJ22A, the TPSMC22AHE3_A/H uniquely combines AEC-Q101 qualification, 185 °C TJ rating, and guaranteed HE3 suffix compliance in a single production part - eliminating qualification overhead for Tier 1 automotive suppliers requiring traceable, pre-qualified components.

FAQ
What is the exact breakdown voltage range for TPSMC22AHE3_A/H?
The TPSMC22AHE3_A/H has a guaranteed breakdown voltage range of 20.9 V (minimum) to 23.1 V (maximum) at 1 mA test current (IT), with 22.0 V nominal. This specification is measured per ANSI/IEEE C62.35 and confirmed across production lots per Vishay Document Number 88407, Revision 19-Jan-2024. The TPSMC22AHE3_A/H maintains this tolerance under thermal stress up to 150 °C.
Is TPSMC22AHE3_A/H qualified for automotive use?
Yes, the TPSMC22AHE3_A/H is AEC-Q101 qualified and explicitly designated for automotive applications via its HE3 suffix, which indicates RoHS compliance and qualification per AEC-Q101 stress tests. It supports operation up to 185 °C junction temperature and meets MSL Level 1 reflow requirements - making it suitable for engine control, body electronics, and ADAS subsystems where TPSMC22AHE3_A/H is deployed as primary transient protection.
What does the "HE3" suffix mean in TPSMC22AHE3_A/H?
The "HE3" suffix in TPSMC22AHE3_A/H denotes a RoHS-compliant, AEC-Q101-qualified variant with matte tin-plated leads meeting J-STD-002 and JESD 22-B102 solderability standards. The "H" indicates 7-inch tape-and-reel packaging (850 units per reel), and "A/H" specifies revision code "A" and packaging type "H". This suffix ensures traceable compliance for automotive BOMs requiring documented qualification evidence for TPSMC22AHE3_A/H.
Can TPSMC22AHE3_A/H replace TPSMC22AHE3_B/H in a design?
Yes - the "A" and "B" revision codes in TPSMC22AHE3_A/H and TPSMC22AHE3_B/H refer only to manufacturing date codes and internal process revisions; electrical, thermal, and mechanical specifications are identical per Vishay Document 88407. No layout or schematic changes are needed when substituting TPSMC22AHE3_A/H for TPSMC22AHE3_B/H, as both share the same SMC package, pinout, and AEC-Q101 qualification status.
What is the maximum clamping voltage of TPSMC22AHE3_A/H at rated surge current?
The TPSMC22AHE3_A/H exhibits a maximum clamping voltage (VC) of 30.6 V when subjected to its rated 49.0 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per Figure 3 in Vishay Document 88407 and defines the upper voltage limit imposed on protected circuits during worst-case transient events - a critical parameter for ensuring downstream ICs like microcontrollers or gate drivers remain within absolute maximum ratings when TPSMC22AHE3_A/H is active.
