1. Automotive Chip DPPM Target Numbers
Here’s a list of typical numeric DPPM targets for automotive-grade semiconductor chips (such as MCU, SoC, sensor IC, power IC), based on industry standards and major automotive OEM/ Tier 1 supplier expectations:
1.1. Automotive Chip DPPM Target Numbers
| Category | Typical DPPM Target |
| General automotive-grade IC | ≤ 10 – 100 DPPM |
| Safety-critical IC (ASIL D) | ≤ 1 – 10 DPPM |
| AEC-Q100 Grade 1/0 devices | ≤ 10 DPPM |
| Mature high-volume products | ≤ 5 DPPM |
| New product introduction (NPI) | ≤ 100 – 500 DPPM (early phase, ramp down after maturity) |
| Tier 1 supplier requirements | Often <10 DPPM, depending on agreement |
| OEM premium segment (luxury brands, EVs) | Targeting zero defect, practically <1 DPPM |
1.2. Field Return DPPM Expectation
| Stage | Typical Field DPPM |
| Initial warranty period | <1 – 5 DPPM |
| Over full product life | <1 DPPM (especially for safety components) |
2. Reference Standards
- AEC-Q100: Defines qualification requirements but doesn’t set DPPM numerically; OEM/Tier1 usually set the numeric targets.
- IATF 16949: Requires zero defect mindset and continuous improvement, driving DPPM targets as low as possible.
- ISO 26262 (ASIL D): Requires ultra-low DPPM for safety-relevant failures, typically pushing for below 1 DPPM.
3. Automotive Chip DPPM Targets (By Type)
Here’s a detailed DPPM target table specifically for automotive power IC, MCU, and radar sensor products:
| Chip Type | Typical DPPM Target (Production) | Field Return DPPM (Warranty Period) | Notes |
| Power IC (e.g., PMIC, LDO, power switches) | 10 – 50 DPPM | <1 – 5 DPPM | Power stages are sensitive to overcurrent/overvoltage; high reliability needed |
| MCU (Microcontroller Unit) | 1 – 10 DPPM | <1 – 2 DPPM | Often ASIL B/C; very mature MCU families aim for <5 DPPM |
| Radar Sensor IC (including RF front-end + DSP) | 1 – 10 DPPM (ASIL B/C); 0.5 – 5 DPPM (ASIL D) | <1 DPPM, sometimes <0.5 DPPM | Safety-critical applications (ADAS); very strict standards |
3.1. Breakdown Context
3.1.1. Power IC
-
-
- Higher initial DPPM acceptable during ramp (<100 DPPM), but mature products must meet <10–50 DPPM.
- OEMs especially strict for power stages used in safety systems (e.g., EPS, braking).
-
3.1.2. MCU
-
-
- High maturity, widely used, so extremely tight DPPM expected; some Tier 1s and OEMs demand <5 DPPM.
- Functional safety (ASIL B/C/D) adds further pressure on safe failure rates.
-
3.1.3. Radar Sensor IC
-
-
- Extremely sensitive; part of ADAS/Autonomous stack, so OEMs push for <1 DPPM, especially under ISO 26262 ASIL D.
- Includes failures from both RF front-end and processing sections.
-
3.1.4. Reference Points
-
-
- Tier 1 suppliers like Bosch, Denso, Continental often demand <10 DPPM at mass production.
- OEMs (e.g., VW, BMW, Toyota) demand near-zero defect for safety components.
- ISO 26262 functional safety may set single-digit or sub-DPPM levels as design targets, especially for latent faults.
